![]() ![]() It can be divided into two groups, namely Fatigue and Insufficiency fractures. Early detection and prompt intervention is necessary to prevent the progression to recalcitrant non-union or malunion.įractures occurring due to repeated micro trauma on the bone over a prolonged time period are called stress fractures. By restoring limb alignment and bypassing the fracture site, it facilitates fracture healing. One patient had infection and wound dehiscence at six months for which debridement done and had poor functional outcome.Ĭonclusion: TKA with long stem gives excellent outcome, irrespective of severity of arthritis associated with stress fracture. All fractures got united at the last follow-up. The mean Knee Society functional score improved from 15.5 (range, −10 to 40) to 76.8 (range, 10–100). The mean knee society score improved from 21.9 (range, −10 to 45) to 82.8 (range, 15–99). The mean tibiofemoral angle improved from 18.27° varus to 1.8° valgus. ![]() Results: The mean follow-up period was 28 (range, 6–60) months. Two patients had two level stress fracture of tibia in the same leg. ![]() All patients were treated with posterior stabilised TKA with long stem, of which, four patients had screw augmentation for medial tibial bone defect and two patients with malunited fracture at stress fracture site required osteotomy, plating and bone grafting. Previous surgery in the same limb, rheumatoid arthritis, valgus deformity were excluded. The mean age was 64 years (range, 52–78) which includes three men and 17 women. Out of 20 patients, five were acute fresh fractures. Methods: We analysed 20 patients from April 2012 to March 2017 with proximal tibia stress fractures associated with knee osteoarthritis of varied grades. We evaluated the radiological and functional outcome of one-stage total knee arthroplasty (TKA) and long stem for patients with varied grades of knee arthritis and proximal tibia stress fractures. Introduction: Proximal tibia stress fractures with knee osteoarthritis pose a challenging situation. ![]()
