Purpose : The purpose of this study was to evaluate results of the arthroscopic treatment of calcific tendinitis of the shoulder resistant to conservative treatment. Materials and Methods : From March, 1996 to June, 1998, fourteen patients underwent shoulder arthroscopy to treat resistant calcific tendinitis of the rotator cuff despite conservative treatment for more than 6 months. Calcium deposits were localized to the supraspinatus tendon only in eleven patients, the supraspinatus and infraspinatus tendon in two patients, and to the supraspinatus and subscapularis tendon in one patient. Each shoulder was evaluated with UCLA shoulder rating scale and Constant-Murley score Results : The Constant-Murley pain score improved from average score 3.2 before surgery to average score 8.3 after surgery, and the UCLA functional average score improved from 4.5 preoperatively to 8.3 postoperatively. Preoperative ROM averaged $110^{\circ}$ of flexion, $45^{\circ}$ of external rotation, $90^{\circ}$ of abduction, and internal rotation with the thumb reaching to the spinous process of the third lumbar vertebra, but postoperative range of motion averages improved as follows: $170^{\circ}$ or flexion, $50^{\circ}$ of external rotation, $140^{\circ}$ abduction, and internal rotation with the spinous process of the twelveth thoracic vertebra. Overall 3 patients were rated excellentm 9 were good, 2 were fair. Conclusion : Shoulder arthroscopy is an effective treatment in patients with refractory calcific tendinitis.

Acromioclavicular (AC) joint cyst is an uncommon presentation around the shoulder joint that is usually associated with chronic rotator cuff pathology and degenerative AC joint arthritis. Understanding the underlying pathophysiology of the shoulder joint is essential for appropriate interpretation of the AC joint cyst, assistance in determining the therapeutic strategy, and prevention of complications after treatment. We present a case of AC joint cyst with an aseptic fistula which was complicated by simple excision for recurred AC joint cyst after multiple aspirations. This case revealed a massive rotator cuff tear involving supraspinatus, infraspinatus, and subscapularis tendon on ultrasonography. We also reviewed the clinical approach and treatment options to be considered for its pathogenesis in the literature.

Background: This study aims to compare the clinical outcomes of steroid injections during the rehabilitation period after arthroscopic rotator cuff repair (ACRC). Methods: Among patients who underwent ARCR, 117 patients who met the inclusion and exclusion criteria were enrolled. Pain and range of motion (ROM) recovery at the 3-, 6-, and 24-month follow-up visits and functional outcome at the 24-month follow-up were compared between 45 patients who received ultrasound-guided subacromial steroid injection at postoperative week 4 or 6 and 72 patients who did not. Functional outcome was assessed using the American Shoulder and Elbow Surgeons (ASES) score and Constant score. Healing of the repaired tendon and retear were observed at the 6-month follow-up via magnetic resonance imaging (MRI) or computed tomography (CT) arthrography. Results: At the 3-month follow-up, the steroid injection group showed lower visual analog scale scores than the control group (p<0.05) and showed faster recovery of forward flexion and internal rotation (p<0.05). From the 6-month follow-up, the two groups did not show differences in pain and ROM, and the ASES score and Constant score also did not significantly differ at the 24-month follow-up. The two groups did not differ in retear rate as determined by MRI or CT arthrography at the 6-month follow-up. Conclusions: This study demonstrated that ultrasound-guided subacromial steroid injection at 4 or 6 weeks after ARCR leads to quick pain reduction and ROM recovery until 3 months after surgery. Therefore, subacromial steroid injection is speculated to be an effective and relatively safe method to assist rehabilitation.

Purpose: The purpose of this study was to evaluate the tendon healing of arthroscopic repair in full-thickness supraspinatus tears. We evaluate the effectiveness of the arthroscopic repair of full-thickness supraspinatus tears by assessing functional improvement. Materials and Methods: Thirty consecutive full-thickness supraspinatus tears were repaired arthroscopically in 19 patients with a one row of anchor and 11 patients with two rows of anchors. Patients ranged in age from 51 to 79 years (average 63 years). Average follow-up was 16 month (range, 12 to 28 months). To evaluate the effectiveness of the arthroscopic repair of full-thickness supraspinatus tears by assessing functional improvement, we calculate the Constant, ASES, UCLA scores. The 30 patients had either an MR Arthrogram (25 cases) or an MRI (5 cases), performed between 5 months and 20 months (mean 10 months) after surgery. Results: The cuff was healed in 21/30 cases (70%) and partially torn in 3 cases (10%) after the arthroscopic repair of full-thickness supraspinatus tear. Although the supraspinatus tendon was totally torn to the tuberosity in 6 cases(20%) after the arthroscopic repair, the size of the tear was smaller than the initial in 5 cases. The Constant score improved from an average of $55.7{\pm}7.1$ points preoperatively to $77.7{\pm}9.7$ points at the last follow-up (p<0.001), and the average ASES score improved from $39.2{\pm}7.4\;to\;72.4{\pm}12.6$ (p<0.001), and the average UCLA score improved from $17.9{\pm}2.2\;to\;26.8{\pm}5.0$ (p<0.001). Strength of elevation was significantly better $(7.1kgs{\pm}2.4)$ in the shoulders with a healed tendon that in those with an total or partial re-tear tendon $(4.5kgs{\pm}1.0)$ (p<0.05). Factors adversely affecting tendon healing were increasing age, Only 41.7% of the repairs completely healed in patients over 65 years (p<0.05). Conclusion: Arthroscopic repair of isolated full-thickness tear of the supraspinatus leads to completely healing in 70% of the cases. Total or partial re-tear of the repaired rotator cuff is associated with a decreased strength. Older patients had significantly lower healing rates.

Purpose: We evaluate the short-term clinical outcome of arthroscopic rotator cuff tendon repair with suture-bridge technique in patients with full thickness rotator cuff tear. Materials and Methods: 29 (male:17, female:12) consecutive shoulders treated with this index procedure and early rehabilitation were enrolled. Mean age was 56.4 years (range, 34~73 years) and mean follow-up period was 13 months (range, 12-15 months). Clinical outcomes were evaluated by using the University of California Los Angeles (UCLA) score, the Korean Shoulder Scoring System (KSS) and Visual Analogue Scale (VAS). Postoperative cuff integrity was evaluated through magnetic resonance imaging (MRI) and categorized by Sugaya classification. Results: Postoperative UCLA scores improved from 16.4 to 31.6 (p< 0.05) and KSS scores showed 88 at 6 months and 92 at last follow up. Preoperative VAS score was 8.6, which was decreased to 2.1 at 3 months and 1.4 at 6 months postoperatively. 28 patients (96.5%) had increase in range of motion. The follow up MRI was taken in 15 shoulders and the cuff integrity was type I in 6 cases, type II in 7, type III in 1 and type V in 1 by Sugaya classification. Conclusion: Arthroscopic suture-bridge technique resulted in good or excellent clinical outcome in 96.5% of the cases, so we think this technique is one of the reliable procedure for full-thicknes rotator cuff tear.

To report the fracture of proximal humerus in the lateral anchor site after suture bridge repair. A 57-year-old female patient with shoulder pain on the right-side was admitted through the emergency room following a car accident. Seven weeks before the accident, the patient had undergone surgery at a different hospital for the repair of supraspinatus tendon rupture on the right-side via suture bridge technique. Humerus surgical neck fracture was confirmed by X-ray, and proximal humerus fracture at the anchor site was confirmed by magnetic resonance imaging. Following 7 months of conservative treatment resulted in satisfactory bone union and motion of the shoulder joint. We report the need of close observation during and after the arthroscopic repair of the rotator cuff in patients with osteoporosis.
