During the period from January 1990 to December 1998 65 patients were operated upon for a Baker's cyst. 41 patients (43 operations) were subjected to a clinical and sonographical follow-up examination and interrogation. In 11 cases, the cysts were merely removed, while an open synovectomy was carried out four times (rheumatics) in addition to the removal of the cysts, and arthroscopy with exstirpation was performed in 28 cases. The total recurrence rate was 14 % (6/43). Any significant differences between the groups were not found (p = 0.291). The overall complication rate was 18.6 %. In case of recurrence, the clinical results were significantly worse (p = 0.036). Apart from technical aspects of operation, the not quantifiable correlation between grade of chondromalacia and the formation of effusions following joint degeneration has to be discussed as a cause for recurrences. If both interventions are carried out in one course, there is no increased operative risk. Especially in cases with intraarticular pathological symptoms arthroscopy should precede each cyst exstirpation. With regard to the frequency of recurrence, the patients' expectation should be preoperatively objectified.
1990年1月至1998年12月期间，65例患者接受了腘窝囊肿手术。41例患者（43次手术）接受了临床和超声随访检查及问诊。11例患者仅切除囊肿，4例（类风湿患者）除切除囊肿外还进行了开放性滑膜切除术，28例患者进行了关节镜下囊肿切除术。总复发率为14%（6/43）。未发现各治疗组之间存在显著差异（p = 0.291）。总体并发症发生率为18.6%。复发时，临床结果明显更差（p = 0.036）。除手术技术方面外，软骨软化程度与关节退变后积液形成之间不可量化的相关性也应作为复发原因进行讨论。如果在一个疗程中同时进行这两种干预措施，手术风险不会增加。特别是对于存在关节内病理症状的病例，关节镜检查应在每次囊肿切除术前进行。关于复发频率，术前应客观评估患者的期望。
