【Abstract】 Objective To make the young patients with osteoarthritis and genu varum of knee delay total knee arthroplasty,to observe the cl inical effect of mosaicplasty of femoral medial condyle, patellar-plasty and high tibial osteotomy inthe treatment of osteoarthritis of knee with varum. Methods From June 2004 to February 2006, 8 patients with osteoarthritisof knee with varum(10 knees) were treated with combined operation such as mosaicplasty of femoral medial condyle, patellarplastyand high tibial osteotomy. There were 2 males with 3 knees, and 6 females with 7 knees,with an average age of 50 years(42-56 years). The left knees and right knees were involved in 3 cases respectively and bilateral knees in 2 cases. All patients hadknee ache after walk or long-time standing. The X-ray showed hyperosteogeny at peri-patella and circum ferential femur-tibialjoint，especially in the medial. The gap between patella and femur narrowed or disappeared，especially in the medial femurtibial
joint. The femoral tibial angel (FTA) was 185-200°(mean 190°). The HSS score of knee was 55-75(mean 60). The history ofknee ache was 1-12 years(mean 5 years). Results All patients were followed up for 7-24 months (mean 15 months). All theincisions healed by first intention, no early compl ication occurred. The cl inical bone heal ing time was 8-11 weeks(mean 9 weeks).Rectification of FTA was 15-30°(mean 20°). Normal weight-loading al ignment was recovered. The valgus angle of knee was 10°.The range of motion of knee was 100-120° after operation, increasing by 5-20° (mean 10°) when compared with preoperation.The X-ray of postoperation showed that genu varum was corrected obviously and that no displacement, loosening and breakageoccurred. The mean score of HSS was 80 (75-88), increasing by 20 when compared with preoperation. Conclusion Mosaicplastyof femoral medial condyle can make articular cartilage repair in certain degrees, patellar-plasty can rel ieve ache of fore region of knee effectively, and high tibial osteotomy can recover normal weight-loading al ignment. The curative effect is good with
the combined methods.
