Weight lifting is commonly associated with an increase in knee injury risk. Local steroid injection is thought to be associated with increased risk of spontaneous tendon rupture. The purpose of this report is to describe incidence of rupture of the patellar tendon after receiving multiple local steroid injections in weight lifters.
Seven weight lifters presented at the hospital with ruptured patellar tendon. All the patients had a history of multiple local steroid injections into the patellar tendon. Each patient received surgical treatment within 72 h after injury.
After an average follow-up time of 26 months, the mean postoperative Lysholm knee score was 94 and the mean Insall-Salvati measurement was 0.96. All seven athletes returned to weight lifting training at 1 year after the operation. They returned to full competition at 18 months after the surgery.
For physicians who treat patellar tendonitis, especially in weight lifters, it is important to recognize the contributing factors for tendon rupture especially in those who have had multiple steroid injections. The functional prognosis of the knee improves if the normal length and strength of the injured tendon have been properly restored.
举重通常与膝关节受伤风险增加有关。局部类固醇注射被认为与自发性肌腱断裂风险增加有关。本报告的目的是描述举重运动员接受多次局部类固醇注射后髌腱断裂的发生率。
七名举重运动员因髌腱断裂到医院就诊。所有患者均有多次向髌腱注射局部类固醇的病史。每位患者在受伤后72小时内接受了手术治疗。
平均随访26个月后，术后Lysholm膝关节评分平均为94分，Insall-Salvati测量值平均为0.96。所有七名运动员在术后1年恢复了举重训练。他们在术后18个月恢复了全面比赛。
对于治疗髌腱炎的医生，尤其是治疗举重运动员的医生，认识到肌腱断裂的促成因素非常重要，特别是对于那些接受过多次类固醇注射的患者。如果受伤肌腱的正常长度和强度得到适当恢复，膝关节的功能预后会改善。
