胫骨干骨折髓内钉治疗后膝关节痛的临床研究

目的 通过对胫骨干骨折髓内钉内固定治疗后膝关节痛的临床观察，探讨膝关节痛的发生和病因。方法 回顾性研究我院1997年1月～2002年12月应用髓内钉内固定治疗胫骨干骨折的1332例病例。所有病例在骨折愈合后均有一次以上随访，平均随访时间为27个月。结果 共有409例胫骨干骨折术后发生患侧膝关节痛；经髌韧带入路组膝关节痛发生率为31.9％，髌韧带旁入路组为28.9％。结论 髌韧带旁入路不能减少胫骨干骨折髓内钉治疗术后膝关节痛的发生。

A clinical study on postoperative knee pain following treatment of tibial shaft fracture by intramedullary nailing

Objective To study the incidence and etiology of knee pain in patients with tibial shaft fracture after intramedullary nailing treatment. Methods From Jan 1997 to Dec 2002, 1332 patients with tibial shaft fracture were treated with intramedullary nailing in our hospital. Their clinical data were retrospectively studied. All the patients were followed up at least once after fracture healing, and the average clinical follow up duration was 27 months. Results 409 of the 1332 cases experienced knee pain. 31.9 percent of the patients treated with transtendinous nailing reported anterior knee pain, and 28.9 percent of the patients treated with paratendinous nailing reported knee pain. Conclusion Compared with the transpatellar tendon approach, the paratendinous approach for nail insertion does not reduce the incidence of anterior knee pain.
