Popliteal cyst: a surgical approach.

Twenty-nine adult patients (30 knees) who failed conservative treatment had surgical excision of a non-rheumatoid cyst. To determine the effectiveness of this surgical procedure, we reviewed the cases of 24 patients (25 knees) who were available for subjective and objective follow up. Twenty of the 25 knees (80%) were rated excellent or good. Three knees had fair results. Two knees continued to have problems and ultimately underwent total knee replacement for degenerative arthritis.
