Avulsion rupture of the flexor digitorum profundus tendon at the distal phalanx is a rare injury. It usually occurs during extension of the DIP joint, while the flexor digitorum profundus tendon is contracted, or when strong extension force is applied, to the distal phalanx. We experienced a patient, combat policeman who had avulsion rupture of flexor digitorum profundus tendon at the distal phalanx after 2 days of combat exercise. Here, we would like to report unusual case of rare tendon injury with studies from other papers.

Purpose: To identify associated findings in glenohumeral joint in rotator cuff tear and evaluate its clinical significance, we examined minor and major changes during arthroscopic or mini open repair. Materials & Methods: We reviewed 66 patients of rotator cuff tear treated from March, 2001 to January, 2004. Of 38 cases of small to medium tear, average age was 53 years old and involved in dominant arm in 27 cases. Of 28 cases of large to massive tear, average age was 58 years old and involved in dominant arm in 26 cases. Minor and major associated changes of the glenohumeral joint were evaluated in the tendon of biceps long head, biceps pulley, cartilage of the glenoid and humeral head, labrum and synovium. Results: Minor changes in biceps tendon were in 35% of cases, biceps pulley in 18%, cartilage of humeral head in 27%, cartilage of glenoid in 18%, labrum in 38%, and synovium in 42%. Major changes in biceps tendon were in 6% of cases, biceps pulley in 35%, arthritis of humeral head in 3%, arthritis of glenoid in 2%, labrum in 6%, and synovium in 21 %. Major changes in biceps tendon were 5% in Group I and 7% in Group Ⅱ(p>0.05) and in biceps pulley, 18% and 57% in each (P<0.05). Minor changes of arthritis were prevalent in glenoid cartilage and major changes were more prevalent in humeral head. There were no differences in minor changes of labrum and synovium, but major changes were more prevalent in Group Ⅱ. Conclusion: The prevalence of intraarticular associated changes of rotator cuff tear were 63% in synovium, 54% in labrum, 53% in biceps pulley, 41% in biceps tendon, 30% in humeral head and 20% in glenoid cartilage in order. Major changes of biceps pulley, humeral head, labrum and synovium were more prevalent in Group Ⅱ.

Simultaneous acute rupture of the anterior cruciate ligament (ACL) and the patellar tendon is a very unusual injury. That is difficult to diagnose in initial evaluation of knee injury, because the patellar tendon rupture is often missed. We report a 26 year-old male patient who was treated with ACL reconstruction using achilles allograft and direct patellar tendon repair with achilles allograft augmentation. The patient had the stable knee and full range of motion. It's clinical results were excellent(Lysholm score 93, Tegner activity score 6).

This study was undertaken to document the clinical results and technical aspects of arthroscopic repair including popliteus tendon as a post for the treatment of complex lateral meniscus in young people indicated as total meniscectomy. From June 2004 to May 2006, we prospectively studied arthroscopic repairs on 32 young people knees with symptomatic complex lateral meniscus that was treated by all inside repair technique using Popliteus tendon as a post. Clinical results were evaluated using Lysholm knee scores preoperatively and at final follow-up. 2nd look arthroscopy or MRI was taken at final follow-up. 80% of patients carried out MRI or 2nd look arthroscopy under permission. Most patients who follow up were able to return to their previous life activities with little or no limitation, and no reoperation was required after an average follow-up of 42.8 months. Mean Lysholm knee scores improved from 65.4 (range, 55 to 75) preoperatively to 93.9 (range, 79 to 100) at the final follow-up (P<.001). 80% meniscus healing was found on arthroscopic or MRI follow up. Conclusively, arthroscopic repair using Popliteus tendon as a post is effective for treating young people with complex lateral meniscus tear as a salvage procedure.

Purpose: Anatomical repair of massive rotator cuff tear has been technically challenging because of medial retraction, muscle atrophy and fatty degeneration. Among several treatment options for massive rotator cuff tear, we reviewed rotator cuff repairs and investigated modalities for improvement of clinical outcomes, decreasing the re-tear rate, and increasing healing. Materials and Methods: Patient-related factors and rotator cuff-related factors were the two major groups of factors we considered when choosing a treatment plan. Results: Mobilization of a massive rotator cuff tear was increased by soft tissue release and by the interval slide technique. After meticulous soft tissue release, anatomical repair could be achieved. If the injury was not amenable to anatomical repair, alternative treatment options such as partial repair, the margin convergence technique and augmentation with a tenotomized biceps tendon were considered. Many reports of massive rotator cuff repair demonstrated satisfactory clinical outcomes, decreased pain, recovery of shoulder functions, and increases in muscle strength. However, the re-tear rate had been reported to be relatively high in long-term follow-up. Conclusion: Despite a high re-tear rate after massive rotator cuff repair, a better understanding of the pathogenesis, progression and clinical symptoms of massive rotator cuff tear and improved surgical materials and techniques will lead to satisfactory clinical outcomes.

The rotator cuff is situated in a potential tight subacromial space and undergoes senescent structural changes commonly observed in other joints of the body. When the cuff fails, spontaneous healing of the torn tendon is not expected to occur, and multiple factors may be responsible. Its fibers are under tension and typically retract on tearing. The subacromial bursal inflammation and alterations in normal glenohumeral kinematics have been considered in the development of symptoms. Controversy continues to exist concerning the pathogenesis of rotator cuff disease. The heterogeneity of the disorder, as well as the notion that rotator cuff disease may not actually represent a continuum of the same process, but rather, is a compilation of independent disorders, may partly explain the differing viewpoints on its origin. Two contrasting pathogenetic mechanisms have been extensively described and include vascular, or intrinsic, causes and impingement, or extrinsic, factors. Other etiologies have also been reported that include trauma, congenital or developmental factors, and instability. For successful treatment of the rotator cuff diseases, it is essential to understand the structure and function of rotator cuff and to clarify the pathogenesis and natural history of its disorder.

Purpose: Rotator cuff tears involving the subscapularis are less common than those involving the superior and posterior rotator cuff. The purpose of the present study was to report the clinical results of repair of isolated traumatic tears of the subscapularis tendon. Materials and Methods: Fifteen patients (13 males, 2 females; mean age 46.2 years; range 35 to 52) with unilateral ruptures of the subscapularis tendon after trauma who underwent arthroscopic repair between February 2003 and October 2008 were reviewed retrospectively. All the cases were isolated tears of the subscapularis without the involvement of any other rotator cuff tendon and were followed for at least two years (mean 28 months). The entire subscapularis was involved in 9 cases and the tear was localized to the upper two thirds in 6 cases. The preoperative and postoperative status of patients with isolated subscapularis tears were analyzed using the Constant Score, American Shoulder and Elbow Society Index (ASES Index) and postoperative integrity was determined through magnetic resonance imaging. Results: The average clinical outcome scores and strength were all improved significantly at the time of the final follow-up. The constant shoulder score improved from 41.5 to 81.3 points (P<0.05) compared to before surgery and ASES index improved from 46.4 to 89.6 points (P<0.05) postoperatively. Thirteen patients (87%) were satisfied with the result of the treatment. The total tears were significantly more improved by surgery than the partial tears. In 12 of 15 patients (80%) were judged to reveal healed tendon on magnetic resonance imaging at a mean of 13 months postoperatively. The postoperative score was significantly lower for the patients with a failed repair than it was for those with an intact repair (P<0.05). Conclusion: Repair of traumatic isolated subscapularis tears through arthroscopic techniques effectively restores patient function with regard to pain, mobility, strength and postoperative tendon integrity. The postoperative integrity of the repair correlates with the functional results and the total tears were more improved by surgery than the partial tears, but future studies may be needed.

Lesion of long head of biceps tendon is one of the causes making an anterior shoulder pain. According to the anthropometric study of the bicipital groove the meanings of the width, depth and the medial wall angle were suggested. Confirming the images and location of the long head of biceps tendon itself would be helpful in diagnosis.

Prolotherapy, the technology for strengthening lax ligaments, has found increased acceptance in recent years. Prolotherapy involves the injection of the irritant solutions into the weakened or stretched ligaments which are a source of chronic pain. This induces an inflammatory response which mimics the normal repair sequence. Various musculoskeletal disorders of lower extremities such as degenerative arthrtitis, ligament and tendon injuries can be treated with prolotherapy. Prolotherapy is a very good, powerful nonsurgical conservative treatment in various musculoskeletal disorders. Ultrasound exam is very useful to find and confirm the exact location of disorders and check the progress in prolotherapy practices.
