Background: We investigated the resolution of pain and functional recovery of shoulder after arthroscopic removal of calcific deposits in patients with chronic calcific tendinitis. Methods: We enrolled 39 patients who were treated arthroscopically for chronic calcific tendinitis that had been non-responsive to at least 6 months of conservative treatment. We evaluated clinical outcome in terms of the American Shoulder Elbow Surgeons (ASES), the Constant score, the visual analogue score (VAS) for pain. We used plain radiography to measure the size of the calcific deposits. We also analyzed the clinical outcomes in terms of whether or not a cuff repair was performed or the degree of removal of calcific deposits. Results: We found that complete resolution of pain took on average 5.7 months after the arthroscopic treatment. The ASES and the Constant score significantly improved from the 3-month follow-up, however it took 6 months until the scores reached on average 80 points or above. We found that these clinical outcomes at the final follow-up did not significantly differ by whether or not cuff repair was performed. Similarly, we found that the clinical outcomes did not significantly differ by the degree of calcium removal. Conclusions: We found that arthroscopic removal of calcification leads to improved clinical outcomes in patients with chronic calcific tendinitis. However, our findings show it takes at least 6 months for the clinical improvement to become statistically significant. We also found that concomitant cuff repairs or the degree of removal of calcification does not affect the clinical outcome of the arthroscopic treatment.

The purpose of this study is to evaluate the cause, size, number, nature and locaton of loose bodies in the knee joint and to describe the proper arthroscopic technique to remae the loose bodies according to the location of them. We retrospectively analysed thirty-three operations of arthroscopic removal of loose bodies from the knee. Eleven males and 22 females were included with average age of 38(range 7-71). Total number of removed loose bodies were more than sixty. The loose bodies were found most commonly at anterior intercondylar notch area. The most common associated pathology was degenerative arthritis. The most common size of loose bodies was in the range of 5mm to 10mm in diameter. The most common nature of loose bodies was osteochondral. The loose bodies located in suprapatellar pouch, medial gutter, lateral gutter. anterior intercondylar notch or posterior intercondylar notch were removed using standard portals such as anteromedial, anterolateral, superomedial and posteromedial portals. The removal of loose bodies located in upper portion of posteromedial or posterolateral compartment were greatly enhanced using posterior trans-septal portal. The proper portals for the visualization and removal of loose bodies were identified according to the location of loose bodies in the knee joint. More skill in the use of the arthroscope is required for the removal of loose bodies than for simple diagnostic arthroscopy.

Purpose : We evaluated the results of the arthroscopic treatment of nine cases of synovial chondromatosis in the knee joints. Materials and Methods : From June 1989 to September 1999, eight patients nine cases with synovial chondromatosis involving knee joints underwent arthroscopic total synovectomy and removal of loose bodies. There were 6 females and 2 males. The average age at surgery was 44.1 years(range, 20-57 years). The average follow-up period was 5.9 years (range, 2.5-7.3 years). All cases had pain and swelling and two cases had locking preoperatively. Flexion contracture was found in three cases. Results : Pathologic finding revealed Milgram I in one case, Milgram II in six cases and Milgram III in two cases. There were six cases of generalized synovial hypertrophy and one case of localized type. All patients had symptomatic relief by arthroscopic total synovectomy and loose body removal. Second arthoroscopic surgery was performed in one patient due to recurred lesions 11 months after the primary surgery. Conclusion : Clinical results of the synovial chondromatosis with arthroscopic total synovectomy and loose body removal were satisfactory. Arthroscopic total synovectomy was also effective for the recurred case.

Background: The purpose of our study was to evaluate the usefulness of hip arthroscopy including extensive capsulectomy for synovial chondromatosis of the hip. Methods: From 2008 to 2016, 13 patients with synovial chondromatosis of the hip were treated with arthroscopic removal of loose bodies and synovectomy using three arthroscopic portals. An extensive capsulectomy was performed to allow the remaining loose bodies to be out of the extracapsular space, and the excised capsule was not repaired. All patients were assessed by clinical scores and the radiographs were reviewed to determine whether the remaining loose bodies disappeared at the last follow-up. Results: Eight men and two women were followed up for a minimum of 1 year (mean, 3.8 years; range, 1 to 6.8 years) after hip arthroscopy. Clinical outcomes such as modified Harris hip score, University of California Los Angeles score, and Western Ontario and McMaster Universities Osteoarthritis Index score improved at the last follow-up. Although seven hips had remaining loose bodies after arthroscopic surgery, the remaining loose bodies disappeared in five hips (71.4%) at the last follow-up. Conclusions: Arthroscopic surgery was useful to treat synovial chondromatosis of the hip. In spite of limited removal of loose bodies, arthroscopic procedures including extensive capsulectomy could be effective for the treatment of synovial chondromatosis of the hip.

Shoulder is a common site for calcific deposit and is frequently asymptomatic. There is a general agreement that calcific tendinitis should be initially treated nonoperatively and excision reserved for cases unresponsive to the conservative measures. There are several reports that arthroscopic excision of symptomatic calcific deposit is proved to be efficient in the calcific tendinitis refractory to nonoperative management. The results of arthroscopic treatment of chronic resistant calcific tendinitis of the shoulder in eleven patients were evaluated. Each patient had shoulder pain for more than one year prior to the arthroscopic surgery. The average age of the patients was 48 years(range 35-70). Arthroscopic calcium removal and subacromial bursectomy was performed in all patients. Arthroscopic acromioplasty was additionally done in four patients. The results turned out to be good in nine patients with full range of motion and complete pain relief. One patient with full motion and occcasional episodes of pain was satisfactory. One patient with persistent pain was unsatisfactory which converted to satisfactory six months later after subacromial injection. So we conclude that the arthroscopic treatment is a reasonable alternative in treatment of the chronic calcific tendinitis resistant to conservative treatment.

The object of this study was to determine rate of ability restoration after arthroscopic surgeries in Thoroughbred racehorses. The racehorses that under arthroscopic surgery due to be injured his limbs were studied during exercise or training at Busan Race Park from 2005 to 2010. Rate of arthroscopic surgical treatments was 1.4% (63/4642). The results of arthroscopic surgery for the removal of osteochondral fragments from 70 limbs in 63 horses are reported. Number of patients under arthroscopic surgery were 63 and 58 horses were recovered from the surgeries and 5 horses were in training or resting at the time of publication. Only 52 of 58 horses had previous race experiences before the surgeries. Success horses of returned to the same level of performance were 31 horses (59.6%) and failed horses were 21 horses (40.4%). Average resting periods in success and failed horses were 7 months and 8.8 months, respectively. Resting periods in success horses were shorter than failed horses.

The development of good quality small-diametered arthroscopes and refined arthroscopic techniques has contributed to the improvement of the subtalar arthroscopy. The therapeutic indications are synovectomy, removal of loose bodies, debridement and drilling of osteochondritis dissecans, excision of subtalar impingement lesions and osteophytes, lysis of adhesions for post-traumatic arthrofibrosis, removal of a symptomatic os trigonum, calcaneal fracture assessment and reduction, and arthroscopic arthrodesis of the subtalar joint. The subtalar arthroscopy can be done in supine position using thigh holder or in lateral decubitus position. The arthroscope generally used is a 2.7-mm 30 degrees short arthroscope. Noninvasive distraction with a strap around the hindfoot can be helpful. Usually anterolateral, middle and posterolateral portals are utilized for inspection and instrumentation within the joint. Twoportal posterior subtalar arthroscopy in prone position can be performed as well with 4.0-mm 30 degrees arthroscope, depending on the type and location of the subtalar pathology. The subtalar arthroscopy is a technically demanding procedure, which requires proper instrumentation and careful operative technique. Possible complications are nerve damage and persistent wound drainage.
