Little information is available on the long-term outcome of jumper's knee, a common problem among athletes.
Our aim was to determine the 15-year prognosis of jumper's knee.
Prospective case control.
The prognosis for jumper's knee was studied using two groups: athletes with jumper's knee and nonsymptomatic control athletes. At baseline, all subjects participated in standardized clinical examinations and measurements, and 15 years later they were asked to respond to a questionnaire.
Twenty athletes with jumper's knee and 16 athlete control subjects responded (response rate 74% and 84%, respectively). The jumper's knee group reported significantly more knee symptoms according to their Kujala score and more knee pain after repeated squatting. Fifty-three percent of the subjects in the jumper's knee group (9 of 17) reported that they had quit their sports career because of their knee problem, compared with 7% of the control athletes (1 of 14). Patellar height was associated with knee symptoms at follow-up.
Jumper's knee causes mild but long-lasting symptoms after an athletic career.
关于运动员常见问题——跳跃膝的长期预后，可获取的信息较少。
我们的目的是确定跳跃膝的15年预后情况。
前瞻性病例对照研究。
采用两组对跳跃膝的预后进行研究：患有跳跃膝的运动员和无症状对照运动员。在基线时，所有受试者都参与了标准化临床检查和测量，15年后他们被要求回答一份问卷。
20名患有跳跃膝的运动员和16名运动员对照受试者做出了回应（回应率分别为74%和84%）。根据库贾拉评分，跳跃膝组报告的膝部症状明显更多，反复蹲起后膝部疼痛也更严重。跳跃膝组53%的受试者（17名中的9名）报告称，他们因膝部问题而放弃了运动生涯，而对照运动员中这一比例为7%（14名中的1名）。随访时髌腱长度与膝部症状相关。
跳跃膝在运动生涯结束后会导致轻微但持久的症状。
