Total Knee Replacement (TKR)

A total knee replacement (TKR) or total knee arthroplasty is a surgery that resurfaces an arthritic knee joint with an artificial metal or plastic replacement parts called the ‘prostheses'.

Knee Arthroscopy

Arthroscopy is a surgical procedure in which an arthroscope (camera) is inserted into a joint. The benefits of arthroscopy involve smaller incisions, faster healing, a more rapid recovery, and less scarring. Arthroscopic surgical procedures are often performed on an outpatient basis and the patient is able to return home on the same day.

Conditions treated by Arthroscopy

  • Meniscus Tear
  • ACL/PCL injury
  • Synovitis
  • Chondral flap
  • OCD lesion
  • Knee cap release
  • Loose bodies

Patient Presentation

Patients usually present following an acute injury to their knee. Pain is the most common presenting symptom. Some patients may experience clicking, catching, locking, giving way or knee swelling. As part of the diagnosis and work up, patients often require a plain xray and MRI scan.

Surgical Risks

Knee arthroscopy is generally regarded as a safe procedure with minimal patient risk. Some of the rare risks associated with this procedure include:

  • Bleeding into the joint (haemarthrosis) - 1 in 100
  • Infection - 1 in 1000
  • Damage to the cartilage or meniscus
  • Failure of the surgery to relieve symptoms
  • Knee stiffness
  • Scaring of the skin or lump under the wound
  • Deep Vein Thrombosis (DVT) - 1 in 750
  • Pulmonary embolus (PE) - risk 1 in 3000
  • Severe pain (Complex Regional Pain Syndrome) - rare

Post Operative

Following surgery you will go to the recovery room for a short period and then back to the Day Admissions ward. You will be allowed home once you have eaten something and also have mobilized safely. Occasionally some patients require crutches. You will have small waterproof dressings on the wounds with a large dressing which can be removed the day following surgery. You will also have an ice pack and we encourage regular icing over the first week. Patients are discharged with a prescription for pain killers and may also need anti-inflammatories. All patients will be reviewed by your surgeon prior to discharge and will be seen again in rooms 10-14 days post surgery.

Anterior Cruciate Ligament Reconstruction

The anterior cruciate ligament is one of the major stabilizing ligaments in the knee. It is a strong rope like structure located in the centre of the knee running from the femur to the tibia. When this ligament tears unfortunately it doesn't heal and often leads to the feeling of instability in the knee.

ACL reconstruction is a commonly performed surgical procedure and with recent advances in arthroscopic surgery can now be performed with minimal incisions and low complication rates.

History and Examination

Patients often give a classic history of their injury. It usually occurs following a non contact pivot injury to the knee however can also occur during contact sports. Classic features of the history include:

  • Twisting knee injury
  • Heard a pop
  • Felt a clunk
  • Could not play on
  • Knee swelling within 4 hours if injury
  • Severe Pain
  • Knee gives way

As part of the work up, patients require a plain xray and MRI of the knee.

Do I need an ACL reconstruction?

The ACL does not tend to heal itself. It is within the knee joint and the joint fluid prevents healing. A new ligament must be reconstructed using another tendon. If you play pivoting sports or have symptoms of instability in daily life consider ACL reconstruction. I would recommend surgery in most patients who wish to continue participation in sport or physical work.

There are definite benefits to surgery. It provides knee stabilization and prevents further damage to structures inside the knee particularly the meniscus and cartilage surfaces of the femur and tibia.

Timing of Surgery

Timing of surgery varies between patients. It is generally recommended that patients have surgery within 6-8 weeks post injury. You must have regained a full range of motion of the knee joint and most of the swelling must be resolved prior to surgery. Some patients have an injury to the medial collateral ligament (MCL) as well as the ACL tear and require a period of knee bracing pre-operatively to allow the MCL to heal. I do not perform the surgery until stiffness is fully resolved.

Graft Types

Many graft types are available to use. These include:

  • Hamstring tendons
  • Patella Tendon
  • Quads tendon
  • Allograft
  • Artificial graft (LARS)

Most surgeons in Australia perform a 4-strand hamstring graft which is stronger than the native ACL. I prefer to use a 5-strand hamstring graft which allows for larger bone tunnels for the graft and indeed a stronger graft. I also regularly use a middle third patellar tendon graft. The long term results and survival of both these grafts in the literature are similar.

The LARS ligament has received a lot of media publicity following its use in some high profile athletes. Only short-term outcomes were available. There are surprisingly few studies reporting on LARS ligament outcomes. Only short term outcomes are available. We do know that shedding of synthetic debris from this ligament inside the knee can cause synovitis and predispose to early arthritis. It is my preference to not use the LARS ligament for primary ACL reconstruction.

Specific Risks of surgery: are all relatively small

  • Infection
  • Deep Vein Thrombosis
  • Excessive bruising and swelling
  • Joint stiffness
  • Graft Failure 5-10%
  • Numbness
  • Nerve or vessel damage
  • Donor site problems
  • Hardware Problems
  • Residual Pain and swelling

Recovery

Following surgery the patient will remain in hospital for one night and will have three doses of post operative antibiotics. The majority of patients will not require a brace and will be bearing full weight as tolerated with crutches upon discharge. I advise early involvement with physiotherapy to for swelling control and knee range of motion. As a rough guideline, patients will be on crutches for 2 weeks, jogging in a straight line by 3 months and running with pivoting by 7 months. A return to competitive or contact sport will be 9-12 months.

Physiotherapy is an extremely important part of recovery. The time commitment to this part of the overall treatment is approximately 9-12 months however your physiotherapist will be your guide.

Patellar (Knee Cap) Problems & Instability

Overview

Knee cap (patellofemoral) instability occurs when the knee cap does not slide centrally within the grove of the thigh bone (Trochlea). The knee cap can partially come out of the groove (subluxation) or completely come out of the groove (dislocation).

Our assessment of patients with patellofemoral instability has improved recently as our knowledge of patello-femoral joint anatomy and its stabilizing factors has increased.

Accurate assessment of the underlying abnormailities in the unstable joint enables formulation of appropriate management plans.

Patellar pain is common in both athletic and nonathletic individuals. Among athletes, men tend to present with more patellofemoral injuries, including traumatic dislocations, than women. In the nonathletic population, women present more commonly with patellar disorders. The three most common causes for patellar dislocation remain: traumatic dislocation, trochlear dysplasia (flattening) and maltracking secondary to bone malalignment. It is essential to understand the underlying cause in order to direct appropriate treatment.

Patellofemoral problems are mainly diagnosed by obtaining a thorough history and performing a physical examination. Imaging studies help confirm the diagnosis. Plain radiography is not as sensitive as magnetic resonance imaging (MRI), but it is the least expensive and most readily available modality.

In general, surgery is more effective in preventing recurrences of dislocation because skeletal and muscular components of the patellofemoral joint and extensor mechanism are realigned; however, surgery also has risks. In a patient with normal anatomy, surgery should be considered an option after all conservative treatment modalities are unsuccessful. Patients with anatomic abnormalities may benefit from earlier surgical consideration.

Clinical History

Facts about recurrent instability include

  • Female teenagers are the most common first time dislocators
  • After a first time dislocation there approximately 17% will have further problems
  • If previous subluxation or dislocation, 50% will have further episodes of instability
  • The younger the age at first dislocation, the higher the risk of subsequent dislocation
  • More severe initial dislocation = higher risk of recurrent dislocation
  • Further risk factors are a family history of patella instability and the risk factors for developmental dysplasia of the hip (first born girl, high birth weight, breech delivery, Caesarian)

Imaging of the Knee with Chronic Instability

These are the imaging techniques and measurements I use for reliability and simplicity and the benefit they provide in decision making.

  • X-rays These can show, Patella alta, Trochlea dysplasia
  • CT scans – CT scans have been widely used in the assessment of chronic instability. I mainly use CT scan to assess complex rotational alignment deformity
  • Magnetic Resonance Imaging (MRI) – MRI scans will reliably demonstrate

Bone abnormalities – Trochlea and patella dysplasia

Large cartilage injuries to the patellofemoral region

Patella tilt any abnormalities to the static constraints e.g. medial patellofemoral ligament rupture and patella alta

Bone bruising of a recent dislocation will be seen on these images

Although far more expensive, MRI is more effective than CT scanning in determining if patellar chondral lesions are present and for determining cartilage thickness and volume. Assessment of patellar cartilage thickness and volume is important to evaluate for osteoarthritis.

Axial views on MRI or CT scans may be used to evaluate the trochlea-tubercle (TTTG) distance. This is the horizontal distance in a vertical plane between the intercondylar notch and the tibial tubercle. Similar to the Q-angle, this evaluates the potential laterally directed vectors on the patella. Some authors suggest that a distance of 2 cm is specific, but not sensitive, for maltracking.

Physiotherapy

During the acute phase of a patellar injury or dislocation, the immediate goals are to reduce inflammation, relieve pain, and stop activities that place excessive loads on the patellofemoral joint. Physiotherapy is an essential component of treatment.

Quadriceps strengthening is initiated during the acute phase. In the event of acute patella dislocation, these should be static exercises initiated during the period of immobilization. Reduction of swelling and regaining knee range of motion are also primary goals. Therapy should also include a protocol for hamstring muscle stretching. Tight hamstring muscles functionally counteract their agonist group, the quadriceps.

Patellar taping (McConnell method)

  • The goals of McConnell taping are to restore proper alignment and control pain

With proper alignment, VMO (quadriceps muscle) retraining is initiated. Once taped, patients should note decreased pain when performing painful activities. The goal of taping is to optimize patellar positioning and facilitate better activation of the medial (inner) patellar stabilizers, particularly the VMO. The technique can be taught to patients to perform themselves. This method was described by a Sydney based physiotherapist and is now used in practice worldwide.

Formulating a Surgical Management Plan

Surgery is only considered if non-operative treatment has failed and the recurrent nature of the disease has resulted in functional impairment.

Surgery may be directed toward either bone or soft tissue components.

I believe the surgical strategy should, wherever possible, aim to restore normal anatomy to the joint, rather than introduce new abnormalities. I will discuss what I believe will be the best option for you.

Bone Procedures

  • Rotational Oteotomy – Breaking the bone and fixing it in a new position to get the knee cap to track better
  • Tibial Tubercle Osteotomy – Moving the bony attachment of the patella
  • Soft Tissue procedure
  • Medial patellofemoral ligament reconstruction – Using the hamstrings tendon to reconstruct the MPFL
  • Lateral release – Releasing tight tissues on the outside of the patella
  • Medial imbrication – Moving the muscle acting on the patella

Presence of Arthritic Change in the Patellofemoral Joint

In the presence of degenerative joint disease (cartilage damage), surgical treatment becomes difficult with a guarded outcome. If the articular lesion is localized to only one side of the joint then cartilage healing (micro fracture) or cartilage restorative (eg MACI or OATS) procedures can be used.

If degeneration is present on both joint surfaces, salvage surgery will be required.

Options include chondroplasty(shaving loose cartilage), lateral release (releasing tight tissue on the side of the knee cap) and tibial tubercle elevation (reseting the position of where the patella tendon attaches).

With failed surgery or advanced arthritis (wear and tear), partial knee replacement or total knee replacement are the only options.

Dr Solomon's Knee Arthritis information:

There are many misleading statements in the media , on the internet as well as claims made by providers who claim that certain tablets, injections or even stem cells can reverse the arthritis process. Unfortunately most of these claims are completely false. There is NO scientific literature evidence that proves that by taking a certain tablet or having an injection into your knee, you arthritis will resolve. There is nothing that can stop a knee joint that has started to wear out from continuing to wear out. There are measures however that can assist with pain management before surgery is indicated.

Stem Cells:

Is this stem cells or stem “sells “ !

We all would like to believe that stem cells would cure our arthritis. Unfortunately this is not the case and NO controlled scientific study has shown this. There are ongoing studies looking at how an injection of stem cells may affect the knee. We are still awaiting the outcome of studies that prove one way or another that stem cells will be a useful addition to the treatment of knee arthritis. Stem cell injections cost close to $9000 and personally I would not be spending that type of money when there is no proof that it will fix my knee pain and reverse my arthritis.

I am all for ongoing research into this area however I would caution patients when deciding whether to spend a fortune on something that is still experimental.

Knee Replacement Surgery

Similar to hip replacement surgery, a knee replacement is indicated when you have advanced osteoarthritis of the knee joint and non-operative measures (eg. Weight loss, anti-inflamatories , physiotherapy etc) are no longer controlling your pain.

Modern day knee replacements are a successful way to treat end stage arthritic knee pain and immobility. It is never really too late to replace the knee so if you can manage with your current arthritic knee……………. keep going until such time as it becomes too uncomfortable and is interfering with your quality of life.

Types of Replacement:

Arthritic knees that require surgery usually require a Total Knee Replacement. A unicompartmental or “half knee” replacement is reserved for a select few patients who have knee arthritis isolated to one area of the knee joint and who satisfy other preoperative criteria. The revision rate of a unicompartmental knee replacement is significantly higher that a total knee replacement (16% vs 6% at 11 yrs) and therefore there are strict requirements in patient selection.

The 2012 Australian National Joint Registry shows that successful knee replacements have an average of 6% revision rate at 11 years following surgery and that if you are over the age of 65 your revision rate is less than 5% and over the age of 75 your revision rate is less than 3%. Younger patients have higher rates of revision.

A total knee replacement is designed to resurface the femur, tibia and patella and in-between the femur and tibia is a layer of polyethelene. The polyethelene (plastic shock absorber) is the bearing surface which ALL knee replacements use. Unlike in hip replacement surgery there is no ceramic on ceramic knee replacement bearing. There is also NO metal on metal bearing so the problem that happened with some metal on metal hip replacements does not exist in knee replacements.

It is anticipated (laboratory studies) that a well aligned and functioning knee replacement should last around 25-30 years before the plastic wears out.

You may have heard about computer navigation , patient specific instruments etc. These are simply tools that some surgeons use to align the replacement during surgery. There are no scientific studies that have proven that a standard surgical technique using instrumentation is any better than computer navigation or patient matched blocks PROVIDED the surgeon doing the surgery is a competent surgeon who aligns the implants correctly and balances the knee joint appropriately.

In other words choose a surgeon who is skilled at would he does using ANY method and you should have a good long term outcome.

Cement or no cement:

Knee replacements may either be cemented onto the bone or used in an uncemented fashion where the bone grows onto the prosthesis. There is no scientific evidence that one method is better than the other. My preference has always been to use cement, as patients tend to recover a little quicker in terms of pain and comfort.

The final word on knee replacement.

Surgery is indicated when non-operative measures no longer control the pain and your quality of life is significantly affected. Over 85% of knee replacements will achieve a good pain free functional result however there are some patients (around 5%) that may still have a niggling ache in the replaced knee joint.

Patients are able to play sport including golf, ski, tennis, bowls, cycle, swimming etc HOWEVER a knee replacement is not designed for impact sports such as running, contact sports, basketball, squash and any sport that results in constant and significant impact on the knee.

We tend to ignore our knees until something happens to them that causes pain. If we take good care of our knees now, before there is a problem, we can really help ourselves. In addition, if some problems with the knees develop, an exercise program can be extremely beneficial. To understand the functions, conditions, surgeries & procedures of the knee better, we have included an interactive animated presentation.

Additional Information on Hip and Knee Surgery
 
This website and the general handout I provide in the office will outline all the general principles of hip and knee replacement surgery, the  realistic outcomes and things you need to be aware of. This handout provides extra information that you may find useful. 
BEFORE SURGERY

Before surgery you will need to attend a pre-admission clinic at the hospital where you will meet a clinical nurse who will go over the basic admission process and post operative course. In addition there are routine pre-operative blood tests and an ECG that are performed. Occasionally a chest X-ray is needed. 
If any significant abnormality is detected in your pre-operative visit, the appropriate action/referral will occur to investigate and treat any issue needing attention. 
If you see a cardiologist routinely and are on a regular blood thinner, please advise your cardiologist you are having a joint replacement and that you need to stop blood thinners such as warfarin, plavix/clopidigrol and aspirin. I am happy to perform the replacement under low dose aspirin (100mg) if your cardiologist insists. 

MEDICATION YOU NEED TO STOP

Please stop all anti-inflamatories (mobic, celebrex, nurofen, voltaren etc ) 1 week before surgery. 
Herbal medication (fish oils, garlic, echinacea, kava, glucosamine etc ) need to be stopped 1 week before surgery as they can cause excessive bleeding. 
 
If you are diabetic it is important that your diabetes is under proper control. Your GP will usually see to this. 
Dental issues. If you have any major dental issues requiring attention please get this done before your joint replacement. 
If you have any prostate issues (Males), please inform me as every patient needs a urinary catheter for 24-48 hrs and prostate problems can result in a difficult catheterisation therefore it is best to have a urologist consult if need be. 

ANTISEPTIC SHOWER SOAP

You will be given an antiseptic soap at the pre-admission clinic that you need to shower with for the 2 days prior to surgery. This will reduce the risk of a skin infection after surgery. 
Please DO NOT shave hair around the hip or knee before surgery. The hospital nursing staff will shave the area if needed using special clippers that do not cut the skin. 

THE SURGERY

The surgery is usually carried out under a combined spinal anaesthetic and light general / sedation. Spinal anaesthesia is safe and has been shown to assist in reducing complications during joint replacement surgery. It provides excellent post operative pain relief. The Anaesthetist will discuss this with you in detail. 
A urinary catheter is used in all cases. Patients with a spinal as well as those who don't have a spinal but get morphine for pain relief, will invariably have difficulty passing urine for 12-18 hrs and hence the need for a catheter. It is much easier to pass a urinary catheter when you are sedated just before surgery than to pass a catheter when you are awake on the ward with a full bladder. 
Removing a catheter is a very easy process done by the ward nurses and is not painful at all. 
Antibiotics are given intravenously for 24-36 hrs and your IV cannula will remain in your arm for this period. The cannula is also often attached to a PCA machine which allows you to administer pain killers when needed. I do not use a PCA in all patients as often (such as in the minimally invasive hip approach) the local anaesthetic and oral pain tablets are sufficient. 
You will be given the appropriate pain relief regime that the anaesthetist will order. This regime is tailored to each individual's needs. 

EARLY MOBILISATION 

The key to preventing thrombosis is mobilisation and exercise . Every patient is fitted with a calf compressor after surgery. This machine compresses the calf intermittently which promotes venous blood flow back to the heart and prevents clots. The compressors are used whilst in bed for the first 48 hrs. The sooner you get out of bed and walk the less the risk of a thrombosis. 
In addition to early mobilisation and calf compressors you will either be given oral aspirin or clexane injections to assist in reducing the incidence of thrombosis. 
I encourage 2 walks a day whilst in hospital. The more you can manage the better but don't overdo things. 
Whilst the risk of a thrombosis is low despite all preventative measures they can still occur and are treated accordingly. I do not perform a routine Doppler scan to check for thrombosis as all studies have shown that routine scanning is a waist of time. 

ANTIBIOTIC POLICY FOR PROCEDURES FOLLOWING JOINT REPLACEMENT

The risk of getting an infection in your replaced joint is extremely rare following routine procedures such as dental work and colonoscopies. 
DENTAL procedures:
For routine dental cleaning after joint replacement surgery there is no need to take antibiotic prophylaxis. For major dental work after a joint replacement ( such as root canal etc) I recommend a single dose of 2gm amoxicillin 1 hour before provided you are not allergic to amoxil. 
COLONOSCOPY, Prostate, Bladder or Gynaecological procedures after joint replacement :
Routine colonoscopy without any major biopsies or risk of bleeding do not require prophylactic antibiotic cover. 
Surgery to the bladder, bowel, gynaecological and prostate surgery require a single intravenous antibiotic dose that is administered by the surgeon at the time of the procedure. Please advise them that you have a joint replacement. 

Some other things about replacements:

All knee replacements have some numbness on the outer side of the wound. This is unavoidable as there is a skin nerve that goes directly across the skin incision and hence is purposefully cut in order to open up the knee joint. It is a minor nerve and the numbness will tend to lighten up over time but is never completely eliminated. 
All knee replacements click. This is normal. It is simply the metal and polyethylene parts touching each other and is no cause for alarm. It is how the joint functions. The clicking noise will tend to get quieter over time. 
Hip Replacements can occasionally click at the extreme of motion. No cause for alarm. Some ceramic on ceramic hip bearings can squeak (rare) again no cause for alarm. 
Intraoperative stability is important in hip replacements. Rarely one may need to tension the hip which can lead to a leg length discrepancy. Various techniques are used to minimise this possibility. 
The key to a successful recovery is motivation to mobilise and to do the exercises the physiotherapist will show you. Hip and Knee replacement surgeries have excellent outcomes provided the patients assist in a motivated recovery.

Arthroscopy of the Knee Joint

Arthroscopy is a surgical procedure in which an arthroscope is inserted into a joint. Arthroscopy is a term that comes from two Greek words, arthro-, meaning joint, and -skopein, meaning to examine.

The benefits of arthroscopy involve smaller incisions, faster healing, a more rapid recovery, and less scarring. Arthroscopic surgical procedures are often performed on an outpatient basis and the patient is able to return home on the same day.

Uni Condylar Knee Replacement

This simply means that only a part of the knee joint is replaced through a smaller incision than would normally be used for a total knee replacement. The knee joint is made up of 3 compartments, the patellofemoral and medial and lateral compartments between the femur and tibia (i.e. the long bones of the leg). Often only one of these compartments wears out, usually the medial one. If you have symptoms and X-ray findings suggestive of this then you may be suitable for this procedure.

Revision Knee Replacement

This means that part or all of your previous knee replacement needs to be revised. This operation varies from very minor adjustments to massive operations replacing significant amounts of bone and hence is difficult to describe in full.

Patellar (Knee Cap)

Knee cap (patellofemoral) instability occurs when the knee cap does not slide centrally within the grove of the thigh bone (Trochlea). The knee cap can partially come out of the groove (subluxation) or completely come out of the groove (dislocation).

Posterior Cruciate Ligament (PCL)

Posterior cruciate ligament (PCL), one of four major ligaments of the knee, is situated at the back of the knee. It connects the thighbone (femur) to the shinbone (tibia). The PCL limits the backward movement of the shinbone. The posterior cruciate ligament is usually injured by a direct impact, such as a motor vehicle accident when the knee forcefully strikes against the dashboard or during sports participation when a twisting injury or overextension of the knee can also cause PCL injury.
