The indications and applications of arthroscopic surgery for the knee joint have increased with the development in surgical techniques and the improvement of arthroscopic equipment. The use of arthroscopic surgery has led to a significant decrease in morbidity for the patient with intra-articular abnormalities, in terms of both the diagnosis and the surgical treatments. Even though arthroscopy is a minimally invasive technique with relatively low morbidity, it is not without risk of complications, of which neurovascular complications are among the most serious and devastating. Here we report on 2 cases of popliteal artery injury during arthroscopic knee surgery and its specific diagnosis and treatment.

Peripheral arterial occlusive disease (PAOD) of the femoropopliteal artery is commonly caused by atherosclerosis. It can present with varying clinical symptoms depending on the degree of disease, ranging from intermittent claudication to critical limb ischemia and tissue loss. Therefore, appropriate and timely treatment is required to improve symptoms and salvage the affected limbs. Interventional approaches for femoropopliteal arterial disease commonly include percutaneous transluminal angioplasty, atherectomy, and stent placement. Over the years, endovascular recanalization has been widely performed for treating PAOD due to continuous developments in its techniques and availability of dedicated devices with the inherent advantage of being minimal invasive. In this review, we introduce various types of endovascular treatment methods, discuss the results of clinical research from existing literature, and illustrate the treatment procedures using representative images.

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.

Atherosclerosis has more than 60% of the causes of arterial occlusive diseases. The abdominal aorta and lower extremity arteries are the most common sites of occlusion. We have treated surgically 2 cases who had intermittent claudication and were diagnosed as simultaneous aortobifemoral and bilateral femoropopliteal obstruction by angiography, but had ineffective results from medical treatment or angioplasty. Simultaneously aortobifemoral bypass using Hemashield Y graft and bilateral femoropopliteal bypass using autologous greater saphenous vein were done. After operations, the symptom disappeared and there were no specific post-operative complications except abdominal wound dehiscence. In postoperative angiography, we had obtained good patency of bypass graft. We are following up patients through the out patient department without recurrence up to 16 months.

Wiring techniques in the fixation of patellar fracture are commonly used. Rigid fixation is essential for early rehabilitation. Breakages of wires after the fixation of patellar fracture are common with extracapsular migration if not removed for long term. But, we experienced a case of patellar fracture with early breakage of wiring and migration of the broken wire fragment into the popliteal fossa through the popliteal hiatus in 64- year-old man and we successfully treated this case, using both arthroscopic and open procedures. So we report this unusual case with a review of current literatures.

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.
