The Clinical Outcomes and Assessment of Quality of Life in Arthroscopic Repair of Isolated Type II Superior Labral Anterior and Posterior Lesion Caused by Sports Injuries from Public / 대한스포츠의학회지

The purpose of this study was to morphologically classify the superior labral anterior and posterior (SLAP) lesion in people with athletic injuries and further research into the clinical result of arthroscopic repair of type II SLAP lesions. January 2005 to June 2012 occurred after sports activity in patients with shoulder pain diagnosed with isolated SLAP lesion by magnetic resonance imaging and arthroscopy were classified according to the tear type. Of these patients, 40 cases of type II SLAP patients were evaluated using American Shoulder and Elbow Surgeons (ASES) questionnaire and range of motion. Also satisfaction of surgery was evaluated by following up through phone calls using translated short form-36 (SF-36). At average of 35 months postoperatively, external rotation decreased slightly from 60.4 degrees to 56.2 degrees, forward elevation and internal rotation were both recovered to a range of pre-surgery but no significant changes were noticed statistically (p>0.05). Visual analogue scale, ASES scores, physical component summary, and mental component summary of SF-36 improved from 5, 1 to 1.2 (p=0.01), from 65.4 to 91.5 (p=0.017), 42.6 to 52.5 (p=0.047), and from 48.5 52.6 to (p=0.036), respectively. In comparison of a group of patients over forty years and less than forty, both groups showed good results, but group of patients less than forty years showed more improvement in pain relief, functional test, and postoperational satisfaction (p=0.004). Arthroscopic repair showed good results in patients with type II SLAP lesion due to athletic injuries especially when they were less than 40 years and it can be regarded as a good treatment with high satisfaction.

The Mid-Term Results of High-Flex Total Knee Arthroplasty: Minimum 5-Year Follow-Up Results / 대한정형외과학회잡지

PURPOSE: The purpose of this study was to evaluate the mid-term results of high-flexion total knee arthroplasty. MATERIALS AND METHODS: We retrospectively reviewed 77 patients who underwent 119 total knee arthroplastys using high-flexion implants (LPS-flex(R) , Zimmer, Warsaw, IN, USA) from November 2004 to June 2006. The mean age was 67.3 years (range, 54-83 years), and the average follow-up duration was 71.1 months. We assessed preoperative and last follow-up functional outcomes with ranges of motion (ROM) and the Hospital for Special Surgery (HSS) score and investigated their ability to squat, sit cross-legged knee, kneel, or stand up from the floor or a chair at the final follow-up. The Knee Society Radiographic evaluation and scoring system was used for radiologic evaluation. RESULTS: The mean ROM increased from 104.7degrees preoperatively to 129.8degrees postoperatively at the final follow-up. The average HSS score improved from 42.7 points preoperatively to 93.5 points postoperatively. At the final follow-up, 33 patients (42.8%) were able to squat; 75 patients (97.4%) were able to sit cross-legged; 27 patients (35.0%) were able to kneel; 45 patients (58.4%) were able to stand up from the floor and 73 patients (94.8%) were able to stand up from a chair. Six cases encountered stiff knees as a complications, and were treated with manipulation procedures. 1 mm radiolucent lines were detected in 5 cases, but none of them were progressive. CONCLUSION: We believe that the hyperflexion implant itself is not a cause of early loosening. Research on reasons regarding early loosening and long-term follow-ups will be needed.

Subperiosteal Ganglion Cyst of the Distal Radius: A Case Report

Subperiosteal ganglion is a cyst that develops from periosteum with cortical erosion. There have been several case reports and most common location is the tibia. Only seven cases of subperiosteal ganglion of the upper extremity have been reported. We report a case of subperiosteal ganglion at distal radius without communication of the wrist joint in a 41-year-old woman. Excision of the cyst and adjacent periosteum were performed without evidence of recurrence.

Intraneural Hemangioma of the Ulnar Nerve / 대한정형외과학회잡지

An intraneural hemangioma is an extremely rare condition. We report here on an intraneural hemangioma of the ulnar nerve. Microscopic exploration and excision of the lesion resulted in complete relief of the patient's symptoms.
