The purpose of this study is to evaluate the final outcome after arthroscopic calcific removal in the calcific tendinitis of the shoulder joint and to analyze the influencing factors to affect the surgical treatment on the final results. From September, 1993 to March, 2000, arthroscopic removal of the calcific deposit in the shoulder joint was performed in 34 consecutive patients who had had typical symptoms and failed with the conservative treatment and 21 cases of 20 patients could be followed up at least 2 years. Fourteen cases(67%) were located in the supraspinatus, 5 cases(24%) in the infraspinatus and 2 cases(9%) in the subscapularis. Preoperative severity of symptoms was correlated with higher postoperative score. Pain was relieved from 7.6 to 0.9(Visual Analogue Scale:VAS) and UCLA score improved from 13.9 preoperatively to 32.0 postoperatively, but there was no statiscally significant difference in according to the deposit size(P=0.386). Pain and UCLA score improved from 7.9 to 0.4 and from 12.7 to 33.0 respectively when a calcific deposit was located in the supraspinatus, from 7.6 to 1.0 and from 14.8 to 33.4 in the infraspinatus but pain relieved from 6.5 to 4.0 and UCLA score improved from 20.0 to 22.5 in the subscapularis and these outcomes were shown a statiscal significance(P=0.001). Completeness of removal did not affect the final results(P>0,05). Excellent was 23.8% in 5 cases, good 66.7% in 14 cases, fair 4.8% in 1 and poor 4.8% in 1, and patients were satisfied with their final results in 81 %.

Osgood-Schlatter's disease is generally treated conservatively. However, surgical treatment is necessary for some patients with recurrent or persistent pain that does not respond to conservative treatment. Most authors recommend the excision of the loose ossicles present around the distal end of the patellar tendon. The authors report the technique of arthroscopic removal of the ossicles for Osgood-Schaltter's disease instead of the conventional technique through the incision at the tibial tuberosity. The advantages of this technique are less damage to the patellar tendon, early postoperative recovery, making no incisional scar in front of the tuberosity which causes the scar discomfort in kneeling, and more cosmetic result.

Recently, a variety of arthroscopic techniques have been reported for the treatment of the displaced tibial eminence fracture. The purpose of this study was to describe details of arthroscopic technique using pull-out wire and to evaluate the results. Eleven patients with irreducible type II and type III tibial eminence fractures underwent the arthroscopic reduction and internal fixation using double strand pull-out wiring. The anterior cruciate ligament tibial drill guide was utilized for the reduction of fracture and passage of the guide pins. The tibial eminence fracture was firmly fixed with double strand 26-gauge pull-out wire(0.45mm diameter). Fracture union was achieved at 7.2 weeks (range, six to eight weeks) after operation. All cases were united at the last follow-up. Subjectively, nine patients had no pain and no restriction of daily activities. Two patients with combined injuries had limitation of knee motion(10 to 130 degrees, respectively) and one patient showed mild anterior laxity. Early rehabilitation was enabled without loss of reduction and breakage of pull-out wire. The arthroscopic reduction and internal fixation using pull-out wire showed good results including early rehabilitation, early fracture union, minimal morbidity, and no requirement of the second operation for hard ware removal.

Synovial chondromatosis is an uncommon condition, and the involvement of the shoulder joint is rare. A 15 year old female patient presented to author's institution for right shoulder pain. We checked the plain radiographs and MRI. And they showed that a diagnosis of synovial chondromatosis in the shoulder, and they also demonstrated that the disease involved the bicipital tendon sheath as well as glenohumeral joint. We removed all loose bodies with total synovectomy by arthroscopic procedure, and a mini-open procedure for the lesions of biceps tendon sheath. Arthroscopic treatment affords excellent visualization of the shoulder joint with less morbidity. However, with current arthroscopic techniques, it is difficult to manage the synovial chondromatosis of biceps tendon in bicipital groove. The authors suggest that the complete elimination of synovial chondromatosis involving shoulder requires a mini-open procedure for the lesions of biceps tendon sheath in addition to the arthroscopic resection of the affected synovium and loose body removal in the glenohumeral joint.

Purpose: Limitation of motion of the elbow joint due to stiffness affect on life quality of the patients. So contracture of the elbow should be treated as soon as possible. Among the many treatment modalities, we described the result of arthroscopic treatment. Materials and Methods: From Mar. 2000 to Mar. 2003, 40 patients, who received the arthroscopic treatment by author for contracted elbow, were the subjects. We estimated the range of motion (ROM) of elbow joint before and after surgery by goniometer. The clinical result was evaluated by Severance elbow scoring system. The final ROM was evaluated at the point of no further increasement of joint motion. Male ware 30 cases, female ware 7 cases, average 42.6 years old and mean follow up period were 31 months. During arthroscopic treatment we had done release of the joint capsule or resection, synovectomy, removal of loose bodies. We used traditional portals. Results: The avarage preoperative ROM of elbow joint was 72.5 degree(range, 5 - 132 degree) and the increasement of ROM was totally 49.3 degree in flexion 26.5 degree and extension 22.8 degree. There was no other complication. Conclusion: Arthroscopic treatment for contracted elbow permit early joint ROM and it decrease the secondary injury to the elbow joint. Also there are few complications. It is thought to be a good treatment modality in contracted elbow joint.

Purpose: To evaluate the results of arthroscopic removal of calcific deposit depending on the phase-dependent progress of recalcitrant calcific tendinitis of the shoulder. Materials and Methods: From January, 2003 to September, 2007, arthroscopic treatment of calcific tendinitis of the shoulder joint, especially supraspinatus was performed in 27 consecutive patients who had had typical symptoms and failed with the conservative treatment and all patients could be followed up at least 6 months. We evaluated the visual analogue scale at preoperative, postoperative 2 weeks and 6 months. The results were compared according to the arthroscopic findings. Results: 11 cases were chalky calcium deposit of arthroscopic finding and 16 cases were toothpaste-like appearance. The VAS was 8.0 of the group with chalky deposit and 8.3 with toothpaste-like deposit preoperatively, which was not significantly different. However, at postoperative 2 weeks, it was 6.7 with chalky deposit and 2.7 with toothpaste-like, which is significantly different. At postoperative 6 months, the symptoms of all patients were resolved. Conclusion: Resorptive phase is well respond to surgical excision at early postoperative evaluation. The phase of calcific tendinitis is one of important factors for rapid resolution of the shoulder pain and functional improvement after arthroscopic treatment.

An 11-month-old, 19.5 kg, intact male Border collie was referred with intermittent left forelimb lameness to the Gyeongsang Animal Medical Center. The symptom was first discovered about 6 months ago, and it has gotten worse for the last 10 days with non-weight bearing on the left forelimb. During the physical examination, the patient showed painful reaction when the left shoulder was abducted. On radiographic assessment, a radiolucent line and some osteophytes were found in both humeral heads. Based on patient's clinical signs and radiographic findings, osteochondritis dissecans (OCD) was very suspicious. So, we decided to perform an arthroscopic surgery on left shoulder for definitive diagnosis and treatment because the right forelimb revealed no clinical signs. During arthroscopic technique, we found a large OCD flap on the caudo-central area of humeral head, and observed severe synovitis over a wide range on posterior area of the articular capsule. The large OCD flap was removed by a grasping forceps, and many joint mice were removed either. Curettage was performed using a curette on the articular surface until hemorrhage occurred, and articular capsule flushed with a lactated-ringer's solution. The patient was discharged on the same day without any specific abnormal status. Antibiotic, anti-inflammatory and analgesic drugs were administered. Mild lameness on left forelimb was observed in 2 weeks after surgery, but after 4 weeks, the patient showed complete normal gait without any lameness. Although surgical removal of OCD flap with arthroscopic was previously reported, We would like note that a large OCD flap can also be removed by arthroscopic surgery in this report.

Heterotopic ossification is formation of bone in atypical extra-skeletal tissues and usually occurs spontaneously or following neurologic injury with unknown cause. We report a 46-year-old female with right shoulder pain and restricted range of motion (ROM) for 3 months without history of trauma. Magnetic resonance imaging (MRI) showed a lesion within the rotator cuff supraglenoid. Excisional biopsy from a previous institution revealed a heterotopic ossificans (HO). Following repeat MRI and bone scan, histopathology from arthroscopic resection confirmed an HO. The patient demonstrated improved pain and ROM at follow-up. Idiopathic HO rarely occurs in the shoulder joint, and resection of HO should be delayed until maturation of the lesion to avoid recurrence. The current case showed that arthroscopic HO resection provides an excellent surgical view to ensure complete lesion removal and minimize soft tissue damage at the supraglenoid area. Furthermore, the minimally invasive procedure of arthroscopy may reduce rehabilitation time and facilitate early return to work.

Purpose: To evaluate the effectiveness of arthroscopic direct cystic removal of popliteal cyst using 70 degree arthroscopy and posteromedial portal. Materials and Methods: From January 2003 to January 2004, 21 patients(23 cases) with popliteal cyst have been treated by direct cystic decompression with arthroscopy. The average age of the 21 patients was 54 years(range 35 to 78 years). There were 5 males and 16 females. Of the 23 cases,8 cases were occured in right side and 11 cases were occured in left side. 4 cases were both sides. In all cases, preoperative MRI were performed to detect combined intraarticular pathology. At 6 months and 1 year postoperatively, follow-up ultrasonography were performed to detect recurrence of cyst. We used Rauschning and Lindgren criteria for clinical evaluation. Results: All cases had no recurrence and no complaints of pain, swelling, or functional impairment at 1 year after surgery. At ultrasonography, no recurrence were founded. One complication was occurred. Postoperatively, Rauschning and Lindgren criteria were more than grade 1. Conclusion: Arthroscopic direct cystic removal using arthroscopy and posteromedial portal is an effective method in popliteal cyst surgery.

Synovial chondromatosis is a rare disease. The knee is the most commonly affected joint but the shoulder joint is very rarely affected. We report typical synovial chondromatosis of the shoulder joint which was managed by arthroscopic removal of multiple loose bodies, synovectomy, good objective and functional outcome was obtained until postoperative 7-year follow-up. Arthroscopy can be used as an effective and useful therapeutic method for synovial chondromatosis of the shoulder joint.
