Abstract
The aim of this retrospective study was to assess the long-term results (minimum ten years) following treatment of medial compartment osteoarthrosis of the knee with high tibial osteotomy using a simple, reproducible technique with minimal internal fixation and early mobilisation.
Between 1980 and 1993, seventy-five lateral, closing wedge osteotomies were performed in sixty-five patients by a single surgeon (ALP). A lateral approach was utilised, with stabilisation achieved using two staples and no use of external splints. Twenty-three patients had died prior to this review (twenty-six knees) and the remaining forty-two patients were invited to attend for independent review. The patients were assessed using the Knee Society Knee Score, Tegner and Lysholm activity score, a patient self-assessment questionnaire and radiological review.
The average age of the patients at surgery was sixty-two years (range twenty-six to seventy-seven years), reviewed between ten and twenty-three years (average seventeen years) following the procedure. Results will be presented with end-points of conversion to arthroplasty and patient dissatisfaction and complications discussed. There were no major complications observed during conversion to total knee joint replacement.
The current role of high tibial osteotomy for the treatment of medial compartment osteoarthrosis will be discussed.
