Unicompartmental Knee Replacement Post Surgery Information

The following is what can be expected after having Unicompartmental Knee Replacement:  

Immediately after surgery you will be taken to the recovery room where you will be motioned. Once stable you will then be transfered to the ward.

Following unicompartmental knee replacement surgery, you will be set up with a button to press to administer pain relief through a machine called a PCA machine (Patient Controlled Analgesia).

The post-op protocol will vary slightly from patient to patient, but generally you can expect your drain to be removed after 24 hours. Once this is removed you can sit out of bed and start moving your knee and walking on it within a day or two of surgery. The dressing will be reduced usually on the second day post-op in order to make movement easier. You will be visited by a physiotherapist who will prescribe exercises and assist you with your rehabilitation and mobilisation.

It is expected you will remain in hospital for three to five days post-surgery. Depending on your needs and situation you will either be discharged home or transferred to a rehabilitation hospital. Either way you will need to do physio exercises on your knee following surgery. A large amount of the long-term results and success of knee replacement surgery depends on how much work you as the patient put in following your operation so it is important to continue with the physio exercises prescribed. 

Once discharged you will be expected to walk with a walker or crutches for six weeks at which stage you can progress to a walking stick. Also at the six-week point, once you feel you have confidently regained control of your leg, you can return to driving.

Knee flexion (bend) will vary from patient to patient but it is expected that by six weeks the knee should be able to bend to 90 degrees. The goal post surgery is to obtain 110-115 degrees of movement.

Upon return home post-surgery special precautions will be needed to be taken around the house. An occupational therapist will assess the home and assist you with this. For example you may need rails in the bathroom or if there are a lot of stairs in your home you may need to modify sleeping arrangements temporarily. 

You should be walking reasonably comfortably by six weeks. More physically demanding activities, such as sports may take three months to be able to do comfortably.  

Concerns: Please contact the office if post-surgery you are worried about your level of pain, have significant bleeding, or have fever or redness around the surgical site.

If you require assistance after hours, please contact the hospital where the surgery was performed and they will contact A/Prof Munjed Al Muderis on your behalf.
