Abstract

PURPOSE: The authors tried to analyze the distribution of associated intra-articular lesions using the arthroscope in excision of popliteal cyst observed in adults.
MATERIALS AND METHODS
The authors examined intra-articular lesions identified by arthroscopic examination on 113 adult patients(117 cases) who were diagnosed as having popliteal cyst that didn't respond to the conservative treatment. And for the operation, intra-articular examination using arthroscope was performed in supine position and the authors performed one-stage excision of cyst without position change of patients.
RESULTS
In 104 cases(88.9%) of total 117 cases, combined intra-articular lesions were identified, Among these, most cases were 72 cases(69.2%) of degenerative chondral lesion and 31 cases(29.8%) of meniscus tear. Communication between cyst and joint was observed in 63 cases(53.8%). There was neither postoperative complication nor recurrence of cyst during out-patient follow-up periods.
CONCLUSIONs
In cases of adult patient who have popliteal cyst that doesn't respond to the conservative treatment, possible associated intra-articular lesions should be considered., and arthroscopic examination and proper treatment far those associated lesions are thought to lower the recurrence rate.
