Knee replacement surgery gives excellent pain reduction and improvement in function. It is only considered in those patients who have “bone on bone” arthritis on an x-ray. This represents severe arthritis. Patients would typically experience severe pain, stiffness and sleep disturbance. Their walking distance is also reduced.
Those patients who have arthritis, but still have some cartilage left in the knee (not bone on bone), may benefit from other forms of treatment. This may be injection of the joint or keyhole surgery. Arthroscopy (keyhole surgery) is especially useful if patients have mechanical symptoms from a torn meniscus or loose piece in the knee.
Total Knee Replacement
I use the PFC knee arthroplasty which has an excellent worldwide experience. 95% of patients should have a satisfactorily functioning knee at 10 years post operatively.
