Treatment
Knee Replacement
Knee replacement resurfaces the worn surfaces of the joint to relieve arthritic pain and restore function. Where only part of the knee is affected, a partial replacement can preserve more of your natural knee.
Total or partial replacement?
Where arthritis is confined to a single compartment of the knee, a partial (unicompartmental) replacement may be suitable, a smaller operation with a faster recovery and a more natural feeling knee. Where arthritis affects the whole joint, a total knee replacement gives the most reliable and durable pain relief. Paddy Subramanian will explain which is right for you using your x-rays and examination.
The procedure
The damaged surfaces of the thigh bone and shin bone are resurfaced with precision-fitted metal and a hard-wearing polyethylene bearing. Careful soft-tissue balancing is the key to a comfortable, stable knee, and robotic assistance is used where it adds accuracy. The operation usually takes 60 to 90 minutes.
Your recovery
Physiotherapy begins on the day of surgery. Most patients go home the same day or after an overnight stay. Most people still need a walking aid through to about six weeks, and drive from around six weeks. Knee replacement recovery is gradual. Swelling and stiffness settle over three to six months, and a full recovery commonly takes 12 to 18 months.
