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.

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.

Background: Acetabular fractures are rare and challenging to treat, and the surgeon’s learning curve for managing these fractures is steep. The incidence of acetabular fractures is low, making it difficult to conduct single-surgeon, single-center studies.Therefore, multi-surgeon and multi-center studies may produce inconsistent outcomes compared to those of single-surgeon, singlecenter studies. According to the authors’ literature investigation, single-surgeon, single-center, large-scale studies on this topic are lacking. Thus, this study investigated the radiological and functional outcomes and prognostic factors in patients with displaced acetabular fractures treated by a single surgeon at a single center and followed up for at least 1 year. Methods: This retrospective study was conducted on 149 patients treated for acetabular fractures at Chungbuk national university hospital between January 2005 and December 2021. Demographic data, time to surgery, and complications were collected using medical records. The Judet and Letournel classification was confirmed using preoperative radiographs, and Matta’s quality of reduction was confirmed using immediate postoperative radiographs. At the latest outpatient follow-up, Matta’s radiological outcome grading and the modified Postel Merle d’Aubigné score were confirmed as radiological and functional outcomes, respectively. Results: The radiological outcome was excellent or good in 131 patients (87.9%) and fair or poor in 18 (12.1%) and influenced by age (p = 0.009), quality of reduction (p < 0.001), and the Judet and Letournel classification (p = 0.025). Functional outcome was excellent or good in 121 patients (81.2%) and fair or poor in 28 (18.8%); this was influenced by the quality of reduction (p < 0.001) and the Judet and Letournel classification (p = 0.030). Conclusions Our radiological and functional outcomes of acetabular fractures were comparable with those of other singlesurgeon, single-center studies regarding the follow-up period. Poor prognostic factors for radiological outcomes included age > 65 years, associated patterns, and poor quality of reduction. Associated patterns and poor quality of reduction were factors associated with poor functional outcomes.
