Background: We analyze the functional evaluation, posterior stability after surgery of acute injuries in the femoral detachment and tibial avulsion fracture of posterior cruciate ligament. Materials and Methods: Twenty two patients who underwent primary repair were followed more than one year after operation (mean follow-up 33.7 months). The patients were evaluated with KT 2000 arthrometer and posterior stress test for posterior stability. Lysholm knee score was used for knee function. Results: Lysholm score revealed 85.3 in femoral detachment group and 91.1 in tibial avulsion fracture group (P<0.05). Posterior displacement of the posterior stress test showed 17.2 mm at initial injury and 8.6 mm at last follow up in femoral detachment group, 16.8 mm at initial injury and 7.1 mm at last follow up in tibial avulsion fracture group. There revealed the tendency of the improved posterior stability of the tibial avulsion group compared with femoral detachment group, but there showed no statistical significance in KT 2000 arthrometer and posterior stress x-ray. Conclusion: Functional results of tibial avulsion fracture group revealed the better outcome compared with femoral detachment group, but the degree of posterior stability in tibial avulsion fracture group showed no statistical significance in posterior stability.

A localized tenosynovial giant cell tumor rarely affects the bilateral knee joint compared to the diffuse form. Only a few cases can be found in the literature, and there is no case report of the bilateral localized form of giant cell tumor causing patellofemoral pain syndrome in Korea. This study experienced a case of bilateral localized giant cell tumor, causing patellofemoral pain syndrome. The tumor was excised arthroscopically and confirmed pathologically. This paper reports this case with a review of the relevant literature.

Prosthetic reconstruction of musculoskeletal defects about the knee for tumor has many advantages, particularly the maintenance of motion and immediate functional restoration. But, prosthetic reconstruction has inherent limitations in terms of long-term durability. The authors have reported here a patient who had mechanical failure at 61 months later following use of a modular resection system to reconstruct the segmental defect of proximal tibia in osteosarcoma. In this case, another technique of extensor mechanism reconstruction using Achilles tendon allograft was attempted. Because of the concerns involving durability of tumor prosthesis, increased emphasis has to be placed on innovation in prosthetic design.

Recently, the interest on anatomical ACL reconstruction with double bundle technique is increased to reproduce the original load distribution, and kinematics of the knee. We developed an arthroscopic double bundle ACL reconstruction technique using autogenous quadriceps tendon with 2 splitted graft and patellar bone plug. The anteromedial bundle and posteolateral bundle of the ACL is replicated with each splitted graft of quadriceps tendon and fixed with biodegradable interference screw on the 2 femoral tunnels. The patellar bone plug of quadriceps tendon is fixed with biodegradable interference screw within the 1 tibial tunnel. We suggest that our technique using quadriceps tendon may be an alternative in arthroscopic double bundle ACL reconstruction.

Synovial chondromatosis is an uncommon disorder characterized by cartilaginous proliferation in the synovium. The cartilaginous nodules occur in the synovial membrane of a joint, bursa, or tendon sheath. It frequents large joints including knee, hip, and elbow. Synovial chondromatosis originating from the first metatarsal is extremely rare. We report a case of 37-year-old man with synovial chondromatosis of the first metatarsal.

Synovial chondromatosis is an uncommon condition and involvement of the glenohumeral joint is rare comparing its involvement of knee and hip. We report a case of synovial chondromatosis with its radiography, MRI and microscopic findings and treatment by arthroscopic synovectomy & loose body removal which have been developed in right shoulder of a 46 year-old-female and presented as impingement syndrome.

Synovial chondromatosis is a rare disease. The knee is the most commonly affected joint but the shoulder joint is very rarely affected. We report typical synovial chondromatosis of the shoulder joint which was managed by arthroscopic removal of multiple loose bodies, synovectomy, good objective and functional outcome was obtained until postoperative 7-year follow-up. Arthroscopy can be used as an effective and useful therapeutic method for synovial chondromatosis of the shoulder joint.

Acute patellar dislocation is a painful, terrifying experience that always occurs suddenly. The recurrence is unfortunately common and each experience is just as painful to the patient. With each acute dislocation, additional intraarticular derangement occurs. Therefore the goals of treatments are not only to relieve acute pain by prompt reduction of the dislocation but also to remove any chondral or osteochondral fragments that may be present within the knee joint and to restore normal patellofemoral anatomy, thereby preventing recurrent dislocation and avoiding future patellar subluxation. To present the details of arthroscopic medial retinacular repair in acute patellar dislocation. we report 2 patients with treatment of acute patellar dislocation with osteochondral loose body.

Osteochondral fracture is common in adolescent and usually occurs in the knee and ankle. Many authors have written concerning osteochondral fracture of the ankle joint, however, many of these pertain only to the talus. The author has found an osteochondral fracture of the articular surface of the medial malleolus within the ankle joint not previously described. We report a case of this lesion that was treated by arthroscopic osteochondral fragment removal.

Symptomatic neuromas after amputation can be troublesome to treat and make it difficult to properly fit a brace. Surgical management is required when conservative management such as prosthetic socket modification or local injections fail. However, small cutaneous nerves adhere to adjacent soft tissue and they are difficult to locate. The authors suggest that ultrasonography guided tattoo localization using a charcoal suspension is useful to find a visually indistinguishable neuroma.
