Abstract:Objective To retrospective evaluate the clinical and radiologic results of double level osteotomy(DLO) for osteoarthritis knees with severe varus deformity and mid-term results.Methods The patients in Beijing Jishuitan Hospital between 2016-2018 who underwent DLO for osteoarthritis knees with severe varus deformity were retrospectively studied.21 patients,including 5 males and 16 females were ultimately enrolled.The age ranged form 25 to 68,with an average age of (47.7±11.8)years.All patients underwent radiological assessment.In the radiological assessment,the following parameters were measured on fulllength weightbearing radiographs both pre and postoperatively:femorotibial angle(FTA),lateral distal femoral angle(LDFA),medial proximal tibial angle(MPTA),and jointline convergence angle(JLCA).In addition,we shared the experience of preoperative planning using Miniacci methods and surgical strategy.We also analyzed the reasons and results of intro-operative and post-operative complications.Clinical results were evaluated using the Oxford knee score(OKS)e.Results The preoperative FTA,LDFA,MPTA,and JLCA values averaged (162.1±7.6)° varus,(79.5±6.2)°,(98.1±7.4)°,and (2.1±2.7)°,respectively.The postoperative FTA,LDFA,MPTA,and JLCA values averaged (178.2±5.6)° varus,(89.5±2.6)°,(90.8±5.2)°,and (1.5±1.3)°,respectively.All of the radiological parameters significantly improved and corrected to the values within normal range(P<0.05).All osteotomy sites were fixed with Tomofix plate,and healed well even with hinge fracture.All patients were followed up for (5±1)years.The OKS was (44±3) in the last phone interview.Conclusion The DLO technique is a valuable surgical technique accomplishing restoration of physiologic knee joint alignment and orientation with significant improvement.The bone healing rate was 100% even with hinge fracture using single plate fixation because all osteotomy sites were fixed with Tomofix locking plate system which is a rigid fixation.
