Knee arthritis often involves more than one compartment in the knee and when this is the case a full knee replacement may be required. The damaged areas of the knee are removed and then replaced by metallic implants on the end of the femur and top of the thigh bone, with a very hard wearing polyethylene (plastic) insert in between which acts as a bearing surface. The back of the knee cap is resurfaced with plastic in approximately 50% of cases.
The surgery takes around 60 minutes to perform and most patients are in hospital for only 2 nights. Knee replacement is major surgery. The initial recovery takes at least 6-12 weeks and most patients are walking independently without crutches at 6 weeks. However, the full benefits of surgery may not be apparent until 12 months post operatively.
All Mr. Smith’s patients enter a unique enhanced recovery programme after surgery to improve patient satisfaction rates and reduce hospital length of stay. His surgery is performed in line with experience gained during specialist fellowship training with Mr. Tim Wilton, president of the British Orthopaedic Association (BOA). Mr. Smith’s choice of total knee replacement is based on evidence from the UK National Joint Registry since 2003. This device has excellent long term results in terms of implant survival and patient reported outcome measures.
