To evaluate the outcome of one stage long stem total knee arthroplasty (TKA) of patients with stress fracture of the proximal tibia of the knee joint. Record of 15 patients, 14 females and one male who underwent one stage long stem TKAfrom the year January 2008 till December 2014 were reviewed retrospectively. Outcome variable was fracture healing which was seen clinically (pain free and postop ambulation) as well as radiologically (union of three out of four cortices). Mean age of the patients were 65 years and the mean BMI was 31. Of the 15 knees 13 had varus malalignment and 2 had valgus malalignment. The mean duration of fracture healing was four and a half months and the mean duration of follow-up was 26 months. All the patients were ambulated full weight bearing with walker. One patient had non-union at fracture site which required bone grafting. Long stem TKA is an effective method of treating tibial stress fractures associated with advance osteoarthritis as it not only restores the normal mechanical alignment but also facilitates fracture healing.
评估膝关节胫骨近端应力性骨折患者一期长柄全膝关节置换术（TKA）的疗效。回顾性分析了2008年1月至2014年12月期间接受一期长柄TKA的15例患者的记录，其中14例女性，1例男性。观察指标为骨折愈合情况，通过临床（无痛及术后行走情况）及影像学（四皮质中三皮质愈合）进行判断。患者平均年龄65岁，平均体重指数为31。15例膝关节中，13例存在内翻畸形，2例存在外翻畸形。骨折愈合的平均时间为四个半月，平均随访时间为26个月。所有患者均使用助行器完全负重行走。1例患者骨折部位出现骨不连，需要进行植骨。长柄TKA是治疗与晚期骨关节炎相关的胫骨应力性骨折的有效方法，因为它不仅能恢复正常的力学对线，还能促进骨折愈合。
