Purpose: The purpose of this study is to evaluate the relationship between trochlear medial facet osteophyte (TMFO) and elbow flexion in the elbow joints without trauma history. Materials and Methods: Twenty five patients, who underwent computed tomography without elbow trauma history, were reviewed. Patients were checked for osteophyte or loose bodies in the coronoid and olecranon sides. The height and length of TMFO were measured. Results: The average elbow flexion contracture was $18.6^{\circ}$, and further flexion was $112.1^{\circ}$. The TMFO height and length was 2.2 mm and 4.7 mm, respectively. The average elbow further flexion was $105.1^{\circ}$ in the coronoid block group (n=14) and $119.1^{\circ}$ (p=0.011) in the coronoid free group (n=11). The relationship between further elbow flexion and TMFO was significant with a partial correlation coefficient of 0.687(p<0.000) in the TMFO length. Conclusion: Elbow joints with longer TMFO length decrease further flexion.

견갑하근 건의 파열의 흔한 원 인은 대개 외상이다. 극상근 건의 파열에 비해 드문 것으로 알려져 왔으나 최근 견관절의 관절내시경 시술이 증가함에 따라 관절면의 부분 파열이 많이 보고되고 있다. 본 증례는 40세 남자 환자로 상완골 소결절에 발생한 골극에 의한 견갑하근 건의 관절면의 부분층 파열에 대해 관절경하 골극의 제거 및 견갑하근 건의 변연절제술 후 양호한 결과를 보였다

Purpose : Authors experienced cases of chronic ACL tear with spur-like lesion on the tibial condyle which is different from the lateral capsular sign and degenerative change and evaluated the significance of 'spur-like lesion' in relations with chronic ACL injury. Material and Method : We have 5 patients with spur-like lesion on the lateral tibial condyle in simple radiogram. The location, shape and size of the lesion were studied using radiogram and MRI. Cause of injury, associated injury and chronicity of the ACL tear were analyzed. All 5 patients were male, and mean age was 33.8 $(17\~46)$ years. Result : The spur-like lesion was located from 3.8 mm(avg.) below the articular surface of the lateral tibial condyle to the apex of the fibular head and protruded laterally or inferolaterally from just posterior to the Gerdy's tubercle with a round or sharp-end triangular shape. Average length was 6 mm and average width ortho base was 9.2 mm. The cause of injury were sports jnjury 4 cases and traffic accident in one. The chronicity of the ACL tear was average 10.7(8 months$\~$23 years) years and medial meniscus tear was shown in all cases and lateral meniscus tear in three. Conclusion : We suggest that a patient who has a history of trauma with spur-like lesion on the lateral tibial condyle of the knee is expected to have chronic ACL tear.

대개 근위부 족저근막염에 의해 야기되는 족저부 뒤꿈치 통증은 흔한 족부 질환이다. 족저근막염을 가진 대부분의 환자에서 비수술적인 치료는 효과적이지만, 통증 해결은 1년까지 요구된다. 수술이 요구된다면, 근막의 절반 이상을 유리하는 것은 기능적인 결손을 피하기 위해 배제되어야 한다. 외측 족저신경의 감압은 무지외전근의 기시부 주위에 통증이 있는 환자에서 추가된고 족저 근막 유리술의 정해진 일부분이 된다. 가끔, 족저부 뒤꿈치 골극 절제술이 필요하지만 이것은 시술의 이환율을 더하고 회복 시간을 지연시킨다.

전방십자인대 재건술시 이식건의 과간 절흔에 대한 충돌을 예방하기 위하여 어느 절도의 절흔 성형을 시행 할 것인가에 대하여는 아직까지 논란이 있으며 수술시 절흔의 형태, 골극 형성 유무, 이식건의 크기 경골 터널의 위치를 고려하여 시행하여야 한다. 절흔 후방의 골 제거가 과도하게 시행 될 경우에는 대퇴골 부착부가 외측으로 전위되어 슬관절의 생역학적 변화를 가져올 수 있고, 주변 관절 연골의 조기 퇴행성 변화를 초래할 수 있으므로 세심한 주의를 기울여야 하며 절흔 성형은 가능한 한 최소화 하는 것이 출혈, 동통 및 부종 등의 술후 합병증을 줄일 수 있다.

Knee osteoarthritis (OA) is a very common musculoskeletal disorder worldwide. The assessment of knee osteoarthritis, which requires a rapid and accurate initial diagnosis, is determined to be different depending on the currently dispersed classification system, and each classification system has different criteria. Also, because the medical staff directly sees and reads the X-ray pictures, it depends on the subjective opinion of the medical staff, and it takes time to establish an accurate diagnosis and a clear treatment plan. Therefore, in this study, we designed the stenosis length measurement algorithm and Osteophyte detection and length measurement algorithm, which are the criteria for determining the knee osteoarthritis grade, separately using CNN, which is a deep learning technique. In addition, we would like to create a grading system that integrates and complements the existing classification system and show results that match the judgments of actual medical staff. Based on publicly available OAI (Osteoarthritis Initiative) data, a total of 9,786 knee osteoarthritis data were used in this study, eventually achieving an Accuracy of 69.8% and an F1 score of 76.65%.

Purpose: This study evaluated the clinical outcome of arthroscopic debridement of anterior compartment and mini-open resection of posterior osteophyte for the treatment of primary osteoarthritis of the elbow. Materials and Methods: Between March 2003 and Feburary 2010, 19 cases who were performed arthroscopic debridement of anterior compartment and resection of posterior osteophyte through mini-open procedure for refractory osteoarthritis of the elbow were enrolled. Average follow-up period was 19 months. Mean age was 49 years old. Clinical results were evaluated by the scoring system of Andrew-Carson Rating Scale (ACRS) and Mayo Elbow Performance Score (MEPS). Results: In the range of motion, flexion contracture was improved from $28.7^{\circ}$ preoperatively to $17.9^{\circ}$ postoperatively, further flexion was improved from $105.1^{\circ}$ to $121.8^{\circ}$. In the scoring system of MEPS, score was improved from 51.1 points preoperatively to 87.9 points in last follow up, 3 cases had in excellent result, 13 good and 3 fair. According to the scoring system of ACRS, score was improved from 92.9 points to 168.2 points, 3 excellent, 14 good and 2 fair. Except one case, all cases returned to preoperative ordinary daily living activity and their own job. Conclusion: For the treatment of refractory osteoarthritis of the elbow, arthroscopic debridement of the anterior compartment and mini-open resection of posterior osteophyte would be helpful on pain relief and functional recovery of the elbow. But this procedure was required long term follow-up in aspect of recurrence of osteophytes and progress of arthritis of the elbow.
