Tennis elbow is a common painful enthesopathy of the lateral elbow that limits upper limb function and frequently results in lost time at work. Surgeons often recommend surgery if symptoms persist despite nonsurgical management, but operations for tennis elbow are inconsistent in their efficacy, and what we know about those operations often derives from observational studies that assume the condition does not continue to improve over time. This assumption is largely untested, and it may not be true; meta-analyzing results from the control arms of tennis elbow studies can help us to evaluate this premise, but to our knowledge, this has not been done.

持续性网球肘症状几乎没有预后价值：系统回顾和荟萃分析。

网球肘是一种常见的肘外侧疼痛性附着点病，它会限制上肢功能并经常导致工作时间损失。如果非手术治疗后症状仍然存在，外科医生通常会建议进行手术，但网球肘手术的疗效并不一致，而且我们对这些手术的了解通常来自观察性研究，这些研究假设病情不会随着时间的推移而继续改善。这个假设很大程度上未经检验，而且可能不正确；网球肘研究控制臂的荟萃分析结果可以帮助我们评估这一前提，但据我们所知，这还没有完成。
