Purpose: To compare the outcome of patients who underwent rotator cuff repair using all-arthroscopic mini-open repair techniques. Materials and Methods: We retrospectively reviewed 44 patients who underwent either arthroscopic (group I) or mini-open (group II) rotator cuff repair. 23 patients underwent an arthroscopic repair and 21 patients had a mini-open repair. The mean age was 50.4 years in the arthroscopic group and 56.7 years in the mini-open group. The outcomes for the 2 groups were evaluated using ROM, VAS, ASES, UCLA scale. Statistical analysis was performed using correlations, T-test, Paired T-test. The mean follow-up period in the arthroscopic and mini-open groups were 24.1months and 26.1months, respectively. Results: The group I (arthroscopic group) had 2 small-sized tears, 10 medium sized tears, and 11 large sized tears (3~5 cm). The group II (mini-open group) had 1 small sized tears, 8 medium sized tears, and 12 large sized tears. The mean cuff tear size of the group I and Group II were 3.8 cm and 4.2 cm, respectively. At last follow-up periods, ROM and functional scores were improved. In the group I and group II, there were no significant difference in ROM, VAS, ASES, UCLA score. Conclusion: The size of the tear did not produce different results at arthroscopic repair group but larger tear size was associated with a worse outcome in mini-open group. There were no significant clinical results between the arthroscopic and mini-open group.

Purpose: To compare the mid-term clinical results of arthroscopic and open repair for large to massive rotator cuff tear. Materials and Methods: We retrospectively reviewed 48 patients who underwent either arthroscopic or open repair for large to massive rotator cuff tear. 28 patients underwent arthroscopic repair and 20 patients had open repair. The clinical outcome for the 2 groups was evaluated using range of motion, Visual Analogue Scale (VAS) for pain and function, American Shoulder and Elbow Society (ASES) score and Korean Shoulder Scoring System (KSS) score. Results: The range of motion, VAS for pain and function and ASES score was improved significantly in both groups at the final follow-up visit compared with preoperative values. However, there were no significant differences between the two groups statistically (p>0.05). There were no significant differences between the two groups statistically at the final follow-up KSS score (p>0.05) either. Conclusion: We could obtain improved mid-term clinical outcomes in both arthroscopic repair and open repair without any statistically significant differences between the two groups.

Purpose: We wanted to evaluate the relationship between the clinical outcomes and cuff integrity after open rotator cuff repair and we wanted to analyze the causes of rotator cuff retear. Materials and Methods: 78 patients who underwent open rotator cuff repair were enrolled from 2004 to 2006. All the patients were observed for a minimum follow-up of 12 months and they were evaluated by magnetic resonance imaging (MRI). The clinical outcomes were accessed by dividing the patients into the retear group and the intact group. The groups were also compared to analyze the cause of rotator cuff retear according to the preoperative tear size, the symptom duration, and so on. Results: The clinical outcome of the retear group (n=22) was improved significantly after operation (p<0.001, p<0.001), but the muscle power was not improved significantly (p=0.099, p=0.243). More retears were found in the patients who had a larger preoperative tear (p<0.001) and the symptom duration of the retear group was longer (p=0.027). Conclusion: Although there were retear after rotator cuff repair, the clinical outcomes were improved. Yet the muscle power of the supraspinatus and external rotator were not improved significantly. There were more retears for the cases that had a larger preoperative tear size and a longer duration of symptoms.

The incidence of rotator cuff tear is increasing rapidly due to the aging of the population and the advancement of radiological diagnosis, and so on. Recently, arthroscopic rotator cuff repair is common way of surgery, and the surgical outcome is comparable to open rotator cuff repair. Arthroscopic repair is one of the minimally invasive procedures itself and may have additional benefits of postoperative pain reduction and early functional recovery. Recently, there has been increasing interest in various methods for improving the functional recovery of patients after arthroscopic shoulder surgery. Various protocols of functional recovery after arthroscopic shoulder surgery are classified by the postoperative period, and they are being studied actively and improved at each stage. On the other hand, there are a range of methods according to the postoperative period, rehabilitation stage, characteristics of individual patients, degree of rotator cuff tear, and underlying disease. Therefore, for functional recovery after arthroscopic rotator cuff repair, it is essential to establish proper regimens for functional recovery.

Partial thickness rotator cuff tears (PTRCTs) are now a well-established clinical entity, yrt there is no consensus in regards to surgical management. Recommended treatment varies widely from simple debridement of the torn tendon to subacromial decompression to excision of the degenerative tendon and repair. Surgery may be performed using an open, arthroscopically assisted (miniopen), or entirely arthroscopic procedure. The advantages and disadvantages of open and arthroscopic procedures may lie in the balance between precision and morbidity. Visualization of both the articular and bursal surfaces is mandatory to determine the level of rotator cuff disease and formulate a treatment strategy. Because these tear often are secondary finding, recognition of the primary pathology is critical. Treatment of the primary problem usually remedies the partial tear. However, when there is significant PTRCT, an arthroscopic or open repair of the diseased tendon will give the most consistent results.

Purpose: This study was designed to evaluate the clinical usefulness of serial ultrasonography (USG) after arthroscopic rotator cuff repair and to assess the re-tear rate and the re-tear time according to the tear sizes and the repair method. Materials and Methods: Between January 2008 and June 2008, 52 patients were treated with arthroscopic rotator cuff repair, Of the 52 patients, 29 patients that had undergone more than six months follow-up underwent preoperative USG examinations and subsequent arthroscopic examinations. MRI and USG findings were compared with intraoperative results of arthroscopic examinations. The postoperative integrity of the rotator cuff was observed using serial USG examination performed postoperatively at two weeks, six weeks, three months, and six months. Results: Small to medium rotator cuff tear were identified in 10 patients where the double pulley suture bridge (DPSB) technique was performed; the re-tear rate was 20%. For 19 patients with large to massive rotator cuff tears, the re-tear rates was 100% for six patients who had undergone tendon to tendon (TT) repair, the re-tear rate was 50% for two patients who had undergone tendon to tendon and bone to tendon (TTBT) repair and the re-tear rate was 55% for11 patients where the DPSB technique was performed. Re-tear rates according to follow-up periods were 7% from two to six weeks, 66% from six weeks to three months and 27% from three to six months postoperatively. Conclusion: Serial USG examinations after arthroscopic rotator cuff repair were useful to assess the re-tear rate and the re-tear time. In addition, USG examination were useful for treatment planning during postoperative rehabilitation.

Purpose: This study evaluated the preoperative and postoperative radiologic findings of patients with complete repairs after massive rotator cuff tears along with the incidence of re-tear and the clinical outcomes. Materials and methods: This study evaluated 33 cases who had open complete repairs for massive rotator cuff tears and these patients were followed up for more than 24 months. The clinical evaluation was performed according to the shoulder joint function test of the American Shoulder and Elbow Surgeons (ASES), and the degree of arthritis related to the massive rotator cuff tears was evaluated using the Hamada classification. Results: The ASES scores improved from 37.6 preoperatively to 85.6 postoperatively. The mean preoperative acromio-humeral interval (AHI) score was 6.5 mm, which increased to 9.3 mm immediately after surgery, and there was a decreased to 6.5 mm noted at the last follow up. The lower radiology stages of arthritis according to the classification showed better preoperative and postoperative results. Conclusion: An open complete repair as the surgical treatment for a massive rotator cuff tear showed satisfactory results for pain relief and an improvement in the shoulder joint function though re-tear after surgery.
