Fabella syndrome is a relatively rare but potentially debilitating condition that causes posterolateral knee pain and swelling, as well as issues with flexion and/or extension of the knee. Irritation, pain, and cartilage damage ensue as the capsule and fabella make contact with the posterior lateral femoral condyle. This condition should be considered in cases of posterolateral knee pain in which other more common pathologies are not readily identified and when patients present with a positive finding of tenderness on examination at the fabella. Initial treatment consists of activity modification and rest, physical therapy, and potentially cortisone injections. When these fail, surgical excision of the fabella should be considered. Surgery in the posterolateral knee, however, requires careful consideration of the immediate and surrounding anatomic structures and arthroscopy, which can be technically challenging. The objective of this technical note is to describe our open technique for symptomatic fabella excision that is easily reproducible, with pearls to minimize risk to the posterolateral structures of the knee.
腓肠豆综合征是一种相对罕见但可能使人衰弱的病症，会导致膝关节后外侧疼痛和肿胀，以及膝关节屈伸问题。当关节囊和腓肠豆与股骨外侧髁后部接触时，会引发刺激、疼痛和软骨损伤。在膝关节后外侧疼痛且未轻易发现其他更常见病变，以及患者在检查时腓肠豆处有压痛阳性发现的情况下，应考虑这种病症。初始治疗包括调整活动量和休息、物理治疗以及可能的皮质醇注射。当这些方法无效时，应考虑手术切除腓肠豆。然而，膝关节后外侧的手术需要仔细考虑直接和周围的解剖结构以及关节镜检查，这在技术上可能具有挑战性。本技术说明的目的是描述我们用于有症状的腓肠豆切除的开放技术，该技术易于复制，并提供一些技巧以尽量减少对膝关节后外侧结构的风险。
