Ganglion in the anterior cruciate ligament is quite rare finding at the time of knee arthroscopy. We experienced a 58 years old female pateint with a ganglion in the anterior cruciate ligamentwho complained gradual development of flexion contracture of left knee joint and treated with arthroscopic excision of ganglion resulted in freedom from flexion contracture of her knee joint.

Purpose: To investigate the outcome of arthroscopic treatment for the complications of knee arthroplasty and to evaluate the effectiveness of arthroscopy. Materials and Methods: We analyzed 25 patients who underwent arthroscopy to treat complications of knee arthroplasty between May 1992 and June 2008. Nineteen cases out of 25 had total knee arthroplasty (TKA) and the remaining 6 cases had unicompartmental knee arthroplasty (UKA). Before arthroscopy, physical examinations and radiographic evaluations were carried out to find out the causes of complications. Joint fluid aspiration and hematologic evaluation were added when infection was suspected. Results: Among the diagnosis at the time of arthroscopy, there were 11 cases of infection, 6 cases of stiffness due to adhesion and fibrosis, and 2 cases of soft tissue impingement in the cases of TKA. Among the cases of UKA, one for each case of meniscal tear, subluxation of mobile insert, hemarthrosis, cement loose body, soft tissue impingement, and stiff knee was found. Nine out of 11 patients who had infection were treated successfully with arthroscopy but the remaining 2 cases underwent revision arthroplasty. Seven patients with arthrofibrosis had improved range of motion from $65^{\circ}$ preoperatively to $105^{\circ}$ postoperatively. The others also showed successful results after arthroscopy. Conclusion: Arthroscopy to treat complications after knee arthroplasty was a safe and effective method when appropriate selection of patients was made.

Several reports have described the increased perioperative risks as well as surgical techniques for performing various procedures in obese patients. However, few reports have addressed the effects of obesity on routine arthroscopic procedures known to be common and safe. Describing the case of a partial meniscectomy performed in a 17-year-old male with a body weight of 120 kg, we review literatures published to the present and provide technical problems and possible complications that can occur when performing routine knee arthroscopy in bariatric patients.

The role of arthroscopy for the diagnosis of polyethylene wear after total knee arthroplasty has been reported previously. In this report, we demonstrate a case of wear of meniscal bearing in unicompartmental knee arthroplasty (UKA) and recurrent meniscal bearing subluxation which was diagnosed by arthroscopy. Arthroscopic examination has its role in diagnosing the wear and subluxation of polyethylene bearing after UKA.

A four-year-old boy with knee pain who had an obscure history showed radiopaque material in the radiograph of the medial side of the knee joint. We successfully treated removal of a piece of glass by arthroscope followed by debridement of erosive cartilage and torn meniscus.

The authors describe one case of a 25-year-old male with nodular tenosynovitis in left knee joint who did not have a history of joint trauma. He had joint pain and restricted flexion of the left knee at 100 degrees. After arthroscopic excision of mass, symptom was relieved completely and the patient had gained full range of motion of the left knee. No recurrence of symptom and loss of motion of the left knee were noticed during follow up period for 12 months.

We present a case of double medial plica that developed on right knee joint. There has been no documented case of double medial plica of the knee joint. In a general way, double medial plica syndrome is very difficult to diagnose because it does rarely develop and symptoms are non-specific or not present. It is difficult to distinguish between pain originating from the medial plica and from other internal derangement of the knee. This patient had symptoms including aggravating right knee pain with sitting position or knee flexion for 3 months. We performed MRI and arthroscopy for more accurate diagnosis. MRI T1, T2 images showed typical double medial plica and we had performed arthroscopic excision of symptomatic medial plica in right knee joint. Arthroscopic resection provided satisfactory relief of symptom.lasting and satisfactory relieve of symptom.
