With the average Australian now living well into their 80s, the likelihood of seniors needing total knee replacement surgery is increasing.
If you have osteoarthritis (OA) in one or both of your knees, the time may come when a total knee replacement is the best solution.
This article will take you through some information about a total knee replacement (TKR) and how to best prepare for one..
What is a total knee replacement?
Simply put, total knee replacement surgery replaces the bony surfaces of the knee joint that have become damaged, with artificial ones. A TKR procedure aims to manage pain, swelling and disability to allow for a better quality of life.
It is always advised to consider conservative treatment such as physiotherapy before undergoing a TKR.
TKRs are usually considered after all other pain management and physical therapies have been exhausted.
The total knee replacement (TKR) journey
Preparation and “prehab”
For planned TKRs, the rehabilitation process should start before the surgery has even taken place (we call this “prehab”).
This prehab period usually lasts for 6-8 weeks. Depending on the individual’s ability to weight-bear, this period involves a progressive resistance training program with stretches and exercises, to take the joint through its desired ‘range of motion’. This might include pool workouts, recumbent bike exercises (whereby the rider is placed in a laid-back reclining position), strength training, and stretches.
Research has shown that pre-operative exercises reduce the need for post-operative care and reduce the length of stay in hospital.
The additional benefits of engaging in prehab include:
- improving pre-op pain,
- developing muscle memory and familiarity with post-op exercises, and
- improving overall strength, fitness and functional performance.
After your TKR
Immediately after the total knee replacement, the recovery process starts. Depending on your surgeon, you may get out of bed on the same day as the surgery, or the following day.
The physiotherapist in hospital will help you to move your knee joint and activate the muscles. They may also use ice to help manage pain and swelling associated with the operation.
Most people will be discharged from hospital three days after surgery.
Rehabilitation
Before returning home, some knee replacement clients head to another medical unit for rehabilitation.
At rehab you will be involved in more intense physio and, in some cases, hydrotherapy to get the knee moving and strong before you head home.
Exercises in this stage are similar to prehab exercises, but may also include a variety of other functional exercises, like step-ups and balance retraining exercises.
Whether you are sent to rehab after hospital or back home, you may still need some further physio in order to get the most out of your new knee.
Our physiotherapists at TPC can come to your home and help you with a strengthening program to get you back to all your pre-operation activities. We can also help you to get back out into the community.
The first three months after a TKR are important and it is during this period the greatest improvements can be made. Therefore, having some form of physical therapy is strongly advised.
An initial assessment with a TPC physio can help you determine what’s the best course of action for you. So if you are currently recovering from a TKR and feel like you could improve your strength and movement or you are planning to have one in the future, our physios can help guide you through a program to get the best outcome from your surgery.
