Sub-vastus approach versus the medial parapatellar approach in primary total knee: a randomised controlled trial ISRCTN44544446

摘要

BackgroundThirty thousand knee replacements are performed annually in the UK. There is uncertainty as to the best surgical approach to the knee joint for knee arthroplasty. We planned a randomised controlled trial to compare a standard medial parapatellar arthrotomy with sub-vastus arthrotomy for patients undergoing primary total knee arthroplasty in terms of short and long term knee function.
