In General, popliteal cyst found in children does not present a symptom and also it rarely causes a complication. The researcher observed an entrapment of tibial nerve and popliteal artery in a child with popliteal cyst without intra-articular lesion, and treated it by using early decompression and prolotherapy, which is presented in this study with literature review.

Pigmented villonodular synovitis most commonly occurs in the knee joint and rarely extends into the popliteal space, which not only has mimicked Baker's cyst but also has been misdiagnosed as malignant tumor. We report a case of a diffuse pigmented villonodular synovitis of knee joint which is extended into the popliteal space as like a popliteal cyst. We treated this case by arthroscopic total synovectomy and excision of cyst. There was no recurrence during more than one year after operation.

A magnetic resonance imaging test was performed on a 56-year-old male patient, who visited with a one-month history of painless swelling at the popliteal area of the left knee. A popliteal cyst and non-calcified loose body in the cyst were identified. Synovial chondromatosis was diagnosed from a histology examination by excision and biopsy. This paper reports this case of extra-articular synovial chondromatosis of the knee with a review of the relevant literature.

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.

The authors reviewed and analyzed the pathologically confirmed 230 cases of benign soft tissue tumors which had been treated at Department of Orthopaedic Surgery in Seoul Hospital, Hanyang University College of Medicine from February 1984 to November 1997. The following results were obtained. 1. The most common benign soft tissue tumors was ganglion(26.5%) followed by hemangioma(19.6%), lipoma(17.0%), Baker's cyst(13.0%) and neurilemmoma(7.0%) in decreasing order of incidence. 2. Benign soft tissue tumors were found evenly distributed over all age group. Hemangioma and lymphangioma were usually found to occur before 20 years old. 3. Female was affected about 1.3 times more common. But, Baker's cyst and neurilemmoma occurred most frequently in male. 4. In children, the most common benign soft tissue tumors was hemangioma followed by ganglion, lymphangioma, and lipoma. In adult, ganglion, lipoma, Baker's cyst, hemangioma were common. 5. The lower extremity was the predominant site of occurrence(60.0%). 6. Benign soft tissue tumors were taken by excision. Local recurrences were developed in 22(9.6%) out of 230 cases, especially in hemangioma.
