From September 1983 to June 1988, the authors could experience 104 cases of meniscal injury from 99 patients by arthroscopic examination. The results of this study may be summarized as follows : 1. There were noticed 35 cases of medial meniscus tear, 35 cases of lateral discoid meniscus tear, 12 cases of intact lat discoid meniscus, 1 case of medial discoid meniscus and 3 cases of lateral meniscal cyst. 2. Most common type of meniscal tear was bucket handle type (35 cases, 34.6%). 3. Most common site of rupture was posterior horn of medial meniscus. 4. Post operative results appeared related with the type of meniscus rupture and combined pathology of knee jont. Bucket handle type rupture was of good prognosis and meniscus lesions with chondromalacia was of poor prognosis.

Acute compartment syndrome of the thigh, which usually occurs in the anterior compartment, is a rare condition. It can have various causes including femur fractures, vessel injury, pseudoaneurysm of the femoral or popliteal artery, and use of anticoagulant. However, there have been few reports of acute compartment syndrome of the thigh without fracture caused by blunt trauma. We report 4 cases of acute compartment syndrome of the thigh without fracture caused by blunt trauma, in which three patients were treated with fasciotomy and a Vacuum-Assisted wound Closure system and the other one had a delayed diagnosis, and eventually underwent above-knee amputation.

PURPOSE: To compare results of minimally invasive plate osteosynthesis using a locking compression plate and a periarticular locking plate in distal femur fractures. MATERIALS AND METHODS: We retrospectively reviewed 31 consecutive femoral fractures who treated by minimally invasive plate osteosynthesis from April 2006 to May 2009. Sixteen patients were treated using a locking compression plate (group A) and 15 patients were treated using a periarticular locking plate (group B). RESULTS: The mean operation time was 78 minutes and 76 minutes (p=0.273), and the mean radiation exposure time was 1.9 minutes and 2.3 minutes (p=0.001) in the group A and B, respectively. The plate bending during operation was performed in 4 cases of group A. The knee range of motion was 117.5degrees and 118.2degrees (p=0.825), and the Lysholm score was 81.3 and 81.8 (p=0.723) in the group A and B, respectively. Schazker criteria showed more than good grade in 93.8% of group A and in 93.3% of group B (p=1.0). CONCLUSION: No significant differences in clinical results were observed between the two groups. However, a lower anatomical compliance was showed in the locking compression plate, and a higher risk of radiation exposure was showed in the periarticular locking plate.

6.Surgical Treatment for Displaced Intra-Articular Calcaneal Fractures.
Journal of the Korean Fracture Society 2016;29(3):221-231
Calcaneal fractures are the most common type of tarsal fracture, and comminuted and bursting fractures are common due to the anatomic characteristics of the calcaneus. Assessment and treatment of calcaneal fractures has improved significantly over time. Despite advancements in surgical techniques and equipment, these fractures remain difficult to treat. In this review article, the physiopathology, classification, and surgical treatments of displaced intra-articular calcaneal fractures are updated.

PURPOSE: To compare the clinical and radiological outcomes of two surgical methods with tension band wire and Hook plate for unstable distal clavicle fractures. MATERIALS AND METHODS: Thirty patients with type II distal clavicle fractures were evaluated, who were operated with tension band wire (Group I) and Hook plate (Group II) fixation, from June 2005 to June 2009, and could be followed-up for more than 1 year after operation. The reduction and union were evaluated by the immediate post-operative and final radiographs. The functional outcome was evaluated by Kona's system and Constant-Murley scoring system. RESULTS: All 30 cases showed bony union. By Kona's functional evaluation, there were 16 cases with excellent and good results in Group I and 14 cases in Group II. The average Constant score was 88.3 (71~100) in Group I and 89.6 (72~100) in Group II, but there was no significant difference in both groups. As complications, there were 2 case with subacromial impingement, and 1 case showed subacromial erosion. There was no K-wire migration, deep infection and acromioclavicular joint arthritis. CONCLUSION: Tension band and Hook plate fixation technique gave satisfactory clinical and radiological results in patients with type II distal clavicle fractures. These results suggest that tension band wire and Hook plate fixation technique seems to be an effective method for type II distal clavicle fracture. But we think thal early removal of plate is necessary due to risks for subacromial impingement and erosion in Hook plate fixation.

Various surgical methods including soft tissue procedures and bone procedures are commonly used to treat knee flexion and contracture deformity. However, several complications such as, neurovascular injury and skin necrosis were reported because of rapid correction. We aim to report good results from gradual correction using Ilizarov following supracondylar osteotomy in a 24-year-old man suffering from fused knee flexion and valgus deformity, a complication developed by septic arthritis.

Femoral head fractures combined with hip dislocation are very rare injuries. In most cases, they result from high-energy trauma to the hip or lower extremity during traffic accidents. Various therapy options have been suggested to treat these injuries. Especially, different joint-preserving surgical options have been described for the treatment of traumatic osteochondral injury of the femoral head in young, active patients. In this report, we present a case that a traumatic osteochondral lesion to the femoral head after hip dislocation was treated with osteochondral autografts (OATS) from the non-weight-bearing area of the ipsilateral inferior femoral head through a surgical hip dislocation. After 1 year, the clinical and radiological outcome was satisfactory with no evidence of posttraumatic osteoarthritis and no pain of patients.

BACKGROUND: This study evaluated the clinical results of arthroscopically assisted single and double bundle tibial inlay reconstructions of an isolated posterior cruciate ligament (PCL) injury. METHODS: This study reviewed the data for 14 patients who underwent a single bundle tibial inlay PCL reconstruction (Group A) and 16 patients who underwent a double bundle tibial inlay PCL reconstruction (Group B) between August 1999 and August 2002. The mean follow-up period in groups A and B was 90.5 months and 64 months, respectively. RESULTS: The Lysholm knee scores in groups A and B increased from an average of 43.3 +/- 7.04 and 44.7 +/- 5.02 preoperatively to 88.1 +/- 7.32 and 88.7 +/- 9.11 points at the final follow-up, respectively. In group A, stress radiography using a Telos device showed that the preoperative mean side-to-side differences (SSDs) of 9.5 +/- 1.60 mm at 30degrees of flexion and 9.8 +/- 1.70 mm at 90degrees of flexion were improved to 2.8 +/- 1.19 mm and 3.0 +/- 1.1 mm, respectively. In group B, the preoperative SSDs of 10.4 +/- 1.50 mm at 30degrees of flexion and 10.7 +/- 1.60 mm at 90degrees of flexion improved to 2.7 +/- 1.15 mm and 2.6 +/- 0.49 mm, respectively. There was no significant difference in the clinical scores and radiologic findings between the two groups. CONCLUSIONS: Single bundle and double bundle PCL reconstructions using the tibial inlay technique give satisfactory clinical results in patients with an isolated PCL injury, and there are no significant differences in the clinical and radiological results between the two techniques. These results suggest that it is unnecessary to perform the more technically challenging double bundle reconstruction using the tibial inlay technique in an isolated PCL injury.
