Purpose: To evaluate the effectiveness of arthroscopic direct cystic removal of popliteal cyst using 70 degree arthroscopy and posteromedial portal. Materials and Methods: From January 2003 to January 2004, 21 patients(23 cases) with popliteal cyst have been treated by direct cystic decompression with arthroscopy. The average age of the 21 patients was 54 years(range 35 to 78 years). There were 5 males and 16 females. Of the 23 cases,8 cases were occured in right side and 11 cases were occured in left side. 4 cases were both sides. In all cases, preoperative MRI were performed to detect combined intraarticular pathology. At 6 months and 1 year postoperatively, follow-up ultrasonography were performed to detect recurrence of cyst. We used Rauschning and Lindgren criteria for clinical evaluation. Results: All cases had no recurrence and no complaints of pain, swelling, or functional impairment at 1 year after surgery. At ultrasonography, no recurrence were founded. One complication was occurred. Postoperatively, Rauschning and Lindgren criteria were more than grade 1. Conclusion: Arthroscopic direct cystic removal using arthroscopy and posteromedial portal is an effective method in popliteal cyst surgery.

Purpose: We evaluated the effectiveness of arthroscopic shaving cystectomy by using posteromedial portal for popliteal cyst with the correction of valvular mechanism. Materials and Methods: We had treated 15 cases of popliteal cyst with arthroscopic shaving cystectomy by using posteromedial portal from April 2004 to June 2005. The mean duration of follow up was 15 months (range: $12{\sim}28$). Functional results were based on the Rauschning and Lindgren criteria. We estimated operative time, time for regaining pain-free full range of motion and checked sonography for recurrence of the cyst at 12 months after the surgery. Results: The functional results by Rauschning and Lindgren criteria were rated Grade 0 or Grade 1 in all cases at last follow up. The average operation time was 45 minutes (range: $35{\sim}70$). All cases regained pain-free full range of motion within five days after surgery and range of motion was also normal at last follow up. There were no recurrence and no walking disturbance in all cases. Conclusion: Arthroscopic shaving cystectomy by using posteromedial portal is one of the effective alternative method of the treatment for popliteal cyst and it is also useful to correct the valvular mechanism.
