Purpose: We compared the clinical and radiological results of meniscectomy with HTO or without HTO for degenerative medial meniscus posterior horn with varus deformity. Materials and Methods: Forty-two patients who had medial meniscus degenerative root tear with varus deformity more than 3 degrees were included for this study. Among them, 30 patients were performed meniscectomy combined with open wedge HTO and 12 patients were performed only meniscectomy without HTO. The mean follow-up period was 52.5 months. The clinical results were evaluated based on symptom improvement, patients' subjective satisfaction for surgery and HSS score. We also compared the osteoarthritic progression between the group on preoperative and at the final follow up radiographs. Results: Symptom improvement was achieved in 83.3% (25 cases) with HTO group and 66.7% (8 cases) without HTO group at final follow up with a significant difference. Patients' satisfaction was achieved in 83.3% (25 cases) with HTO group and 58.3% (7 cases) without HTO group which has a significant difference. The HSS score was improved in both group (90.8: with HTO group, 89.0: without HTO group) at the final follow up without significant difference. WOMAC score was improved in both groups at the final follow up without significant difference. There were no significant differences in the osteoarthritic progression between two groups. Conclusion: The good clinical result for treatment of patient who have medial meniscus degenerative root tear with varus deformity, proximal high tibial osteotomy is considered absolutely necessary. However, the progression of degenerative arthritis, its effect on long term follow up will be needed.

Purpose: The purpose of this study was to document the structural features of the tendinous portions within the non-pathologic subscapularis muscle by performing high resolution MR imaging of the shoulder. Materials and Methods: Between April 2007 and May 2010, we retrospectively obtained the MR scans of 88 consecutive young patients (88 shoulders) who were in their twenties. MRI and MR arthrography were performed using a 3.0-T system for the evaluation of glenohumeral instability and nonspecific shoulder pain. None of the patient in this study had any evidence of injury to the tendon or muscle belly of the subscapularis. On MR images, we recorded the transverse length of a stout tendinous band and the total tendinous portion of the subscapularis. In addition, we recorded the number of intramuscular tendinous slips of the susbscapularis. Results: The mean transverse length of the tendinous band was 15.0 mm (range: 8 to 20 mm). The mean transverse length of the total tendinous portion was 48.9 mm (range: 40 to 60 mm). The number of intramuscular tendinous slips on the base of the glenoid fossa was 3 in 20 (22.72%), 4 in 45 (51.14%) and 5 in 23 shoulders (26.14%). On the lateral portion, the intramuscular tendinous slips became gradually rounder and thicker and they gave converge in the superior direction. Conclusion: In this study, the structural features of the tendinous portions of the subscapularis on the MR scans were identified. This will in return give good justification for the lines to be pulled during biomechanical stimulation and also for the surgical approach to restore the biomechanical function.

Shoulder arthroscopic surgeries are an accepted technique for many shoulder disease and have many advantages over open surgeries. To date, shoulder arthroscopic surgery have been rare complications that compromise patient airway, caused by the leakage of irrigation fluid out of the shoulder joint space into the surrounding soft tissues and then the neck and the pharynx. This report presents a case of life-threatening airway obstruction due to extra-articular saline collection during arthroscopic rotator cuff repair. In concluding we should hourly check the patient's neck swelling undergoing shoulder arthroscopic surgery, because anesthetized patients cannot complain of the airway problem may progress until it becomes life-threatening.

Hemifacial microsomia is a term used to describe a facial anomalies caused by the defect of anatomic structures originated from the first and the second branchial arches. The defect area encompasses some facial areas including mandible, facial muscles, masticatory muscles, cranial nerves, auricles, etc., and the degree of manifestations of the anomalies is extmely diverse. A 20-year-old man complaining of facial asymmetry and malocclusion visited our hospital. An orthognathic surgery was performed for the correction of hard tissue anomalies and then autogenous dermis-fat autotransplantation was done for the improvement of remaining soft tissue defect. The result was esthetically good and the case was presented here.

Many rotator cuff tears are operatively treated in recent years. Postoperative rehabilitation of rotator cuff repair is as important as diagnosis of disease or surgery itself. And it is a crucial factor on the prognosis of the surgery. For appropriate rehabilitation, surgeon should have knowledge about the anatomy and biomechanics of shoulder. The purposes of postoperative rehabilitation are to avoid additional injury, to decrease inflammation, to help healing process of collagen, to strengthen weak muscle, to recover decreased range of motion, to increase endurance of muscle and to protect the repair site and deltoid. These protocols must be individualized according to the condition of the patients.

Object: To determine the sensitivity, specificity, and positive and negative predictive values of an empty can test for diagnosing supraspinatus tendon tear. Methods: We reviewed 146 patients who have shoulder pain with limited active range of motion. We evaluated patients according to empty can test. Sensitivity, specificity, and positive and negative predictive values for supraspinatus test was estimated using arthroscopic evaluation. Results: A hundred and twenty-four of 127 cases with positive empty can test had supraspinatus tendon tear. Of 19 samples with negative empty can test, 15 had no supraspinatus tear. Sensitivity, specificity, and positive and negative predictive values for the empty can test were 97.6%, 83.3%, 97.6%, and 78.9%, respectively. Conclusions: Empty can test was found to have a high sensitivity and good positive predictive value in identifying the tear of rotator cuff tendon. We concluded that empty can test of the shoulder is a reliable diagnostic method which could be used for the diagnosis of rotator cuff tear.

Segmental zoster paresis is characterized by focal, asymmetric motor weakness in the myotome corresponding to the dermatome of the rash. A 73-year-old man, who presented with severe right shoulder pain and shoulder girdle muscle weakness, was diagnosed with segmental zoster paresis involvement of the C5⁣-C6 motor roots as a complication of herpes zoster. Girdle muscles (supraspinatus, deltoid and infraspinatus) atrophy had developed in his right shoulder. An MRI showed rotator cuff tearing in his right shoulder; therefore, an arthroscopic rotator cuff repair was performed. Herein, this case is presented to emphasize the importance of considering post-herpetic segmental motor paresis in the differential diagnosis of acute painful motor weakness of the upper extremities.

Biceps tendon dislocation combined with rupture of subscapularis tendon is not a common lesion and there has been few case reported in Korea. We experienced one fifty Six years old male patient who shows typical features on physical examination and roentgenographic finding. He was injured by direct trauma on his right shoulder in adducted and external rotated position. He showed positive findings on passive external rotation test and lift-off test. On MR!, the subscpaularis tendon was totally ruptured and the biceps tendon was dislocated to anteromedial aspect of the glenoid labrum, which was typical finding. On the arthroscopic examination, the subscapularis tendon was totally ruptured from its humeral attachment and the biceps tendon was not seen in its normal anatomical position and it was dislocated antermedially to the glenoid labrum. We repaired the subscapularis tendon to humerus by use of suture anchor and the biceps tendon was relocated to its normal anatomical position in the intertubercular groove. On the post operative 6 months follow up, the patient shows improvements in his subjective symptoms and active range of motion.

Most pigmented villonodular synovitis (PVNS) is occurred in knee joint and finger of hand. PVNS is rarely occurred in shoulder joint. In English and French literatures, less than 30 cases were reported. We report 3 PVNS cases with rotator cuff tears, which was treated by arthroscoic extensive synovectomy, debridement and rotator cuff repair. The PVNS with rotator cuff tear in shoulder joint was rarely reported in the Korean literature.
