To evaluate the clinical efficacy of operation methods with or without a turned-over patella for treatment of C3-type patellar fractures.
A total of 68 patients with C3-type patellar fractures undergoing open reduction and internal fixation were retrospectively selected and treated with a turned-over patella surgery (turned-over patella group, n = 30) or conventional therapy without turning over the patella (conventional group, n = 38). The intraoperative and postoperative indicators of the two groups were assessed and comparatively analyzed.
The bedridden time was significantly shorter in the turned-over patella group than in the conventional group (P = 0.002), while the range of motion (ROM) of knee joint was significantly higher in the turned-over patella group (P = 0.044). The Lysholm score was slightly higher in the turned-over patella group than in the conventional group, but the difference was not statistically significant (P = 0.055). No significant difference was observed between the two groups in terms of the operation time (P = 0.096), intraoperative blood loss (P = 0.543), time of weight bearing (P = 0.312), fracture healing time (P = 0.272), or complications (P = 1).
The turned-over patella operation method exhibited some superiority to conventional reduction-fixation approach for treatment of C3-type patellar fractures in terms of efficacy and safety by enlarging the ROM of the knee joint and promoting functional recovery.
评估髌骨翻转与不翻转术式治疗 C3 型髌骨骨折的临床疗效。
回顾性选取 68 例行切开复位内固定术治疗的 C3 型髌骨骨折患者，其中采用髌骨翻转术（翻转髌骨组，n=30）或不翻转髌骨的常规治疗（常规组，n=38）。评估两组患者的术中、术后指标，并进行比较分析。
翻转髌骨组的卧床时间明显短于常规组（P=0.002），膝关节活动度（ROM）明显高于常规组（P=0.044）。翻转髌骨组的 Lysholm 评分略高于常规组，但差异无统计学意义（P=0.055）。两组的手术时间（P=0.096）、术中出血量（P=0.543）、负重时间（P=0.312）、骨折愈合时间（P=0.272）及并发症发生率（P=1）差异均无统计学意义。
与常规复位内固定术相比，髌骨翻转术治疗 C3 型髌骨骨折在扩大膝关节活动度、促进功能恢复方面具有一定优势，且安全有效。
