Abstract:
Objective:To evaluate the safety and effectiveness of distal femoral osteotomy combined with arthroscopy in the treatment of valgus knee.Methods:A retrospective analysis was conducted on 24 patients (25 knees) with valgus knee osteoarthritis admitted to the First Hospital of Jiaxing from January 2017 to December 2020 who underwent distal femoral osteotomy combined with arthroscopic surgery and were fixed with domestically produced distal femoral locking plates. The changes in hip knee ankle angle (HKA), distal lateral femoral angle (LDFA), knee joint range of motion (ROM), and knee joint function score (HSS) of the American Special Surgery Hospital before and after surgery were statistically analyzed.Resultsl:A total of 24 patients (25 knees) were followed up for (15.6±2.3)months. HKA increased from (171.22±2.51)° before surgery to (179.24±1.86)° at the last follow-up; LDFA increased from (82.17±2.03)° before surgery to (88.57±1.53)° at the last follow-up; The differences were statistically significant ( P<0.05). The HSS score improved from preoperative (60.27±6.04) to the last follow-up (87.80±5.50), with a statistically significant difference (all P<0.05). One out of 25 knees experienced loss of osteotomy angle, without insufficient or excessive correction, infection, and non union of fractures. Conclusions:The use of distal femoral osteotomy combined with arthroscopic surgery for the treatment of valgus knee osteoarthritis is a safe and reliable method. Retaining the lateral bone hinge during osteotomy is an important factor in maintaining the osteotomy angle and fracture healing.
