Partial Knee Resurfacing

Let’s go in to detail of what having a partial Knee resurfacing means, and how the process of actually coming to hospital and having your surgery will work.

A partial replacement or resurfacing means we only deal with one specific worn out area of your Knee. This can be the medial surfaces between the femur (thigh) and tibia (shin) or the lateral side. We can also just resurface the area of the joint between your patella (kneecap) and the femoral trochlea (femoral groove). Your ligaments all remain intact and the feedback from them make a resurfacing feel much more natural and much like your original Knee.

When you arrive in to hospital you will be taken up to your room and checked in by one of the nursing staff. Mr Frame and the anaesthetic team will confirm what you are having done and answer any questions you might have. Then a mark will be drawn on to the Knee to be operated on to confirm and to be as safe as possible.

You will then be taken down to the theatre suite and further safety checks again will be made and you then go in to the anaesthetic room.

Once you are under anaesthetic be that a spinal or general we then apply a tourniquet to allow surgery to be blood free, and position the leg to help us carry out the surgery.

An incision is made and the old worn out joint surface is removed and shaped to allow us to inlay the new partial resurfacing to match your original joint. This new titanium and cobalt chrome partial resurfacing joint is cemented in place with PMMA (a special polymer glue). A gliding surface is the clipped in to the titanium part to allow almost frictionless movement. The joint is them washed with pulsed water jets and the knee closed with sutures. Mr Frame then closes the skin with absorbable sutures, glues the skin and places a special watertight transparent dressing. This keeps the wound sterile until healed.

You are then moved to recover to waken up under close one on one care. We then move you back up to your room. Keeping your pain controlled is very important and something we work hard to do.

You can begin moving, bending and walking as soon as a few hours after surgery.

An X-ray is taken the next day to confirm the position of the new implants. Once you are safe and pain controlled we get you up and home. To reduce your risk of deep vein thrombosis you have compression socks for 6 weeks and an oral anticoagulant for 2 weeks.

Physio will see you before you leave and as much as required on discharge.

At 2 weeks the wound is reviewed.

At 6 weeks we see you in clinic and most have a nicely healed wound, normal bend and are walking comfortably without aids.
