Purpose: We reported the results and efficiency of arthroscopic treatment in a state of the lateral traction about the degenerative arthris of elbow Materials and Methods: Twenty one elbows with the degenerative arthritis who were followed up for at 12 months were enrolled in this study. Male were 15 cases, female were 6 cases, the mean age was 47 years and right dominant hand was 14 cases. In all cases, during arthroscopic treatment under the traction of 10 pounds, we had done synovectomy, excision of loose body and anteroposterior spur. After operation, immobilization was done in the full extension state, and then continuous passive motion (CPM) was started two day Results: The average preoperative ROM of the elbow joint was $30{\sim}l15$ degree and the average postoperative ROM of the elbow joint was $5{\sim}130$ degree. The increasement of ROM was totally 41 degree in extension 25 degree and flexion 16 degree. The decrement of VAS in pain was from 7.5 into 2.3 and the increasement of the satisfactory function was from 1.8 into 9.0. Complication was in two cases. One was paresthesia of ulnar nerve, but resolved. The other was bullae formation around the elbow joint, but cured. Conclusion: Regarding degenerative arthritis of elbow, arthroscopic treatment showed excellent result in recovery of range of motion and relief of pain. We could obtain good visual field with distraction in lateral position.

Purpose : To review the operative results and find out better method of a treatment of suprascapular nerve entrapment syndrome caused by ganglion. Materials and Methods : From March of 1996 to May of 2001, thirteen cases of suprascapular nerve entrapment syndrome caused by ganglion were reviewed which were diagnosed using physical examination, EMG and MRI. All of them were treated with open exision of ganglion, nerve decompression and arthroscopic examination. The clinical results were evaluated using subjective recovery of muscle power and ASES (American Shoulder and Elbow Surgeons) score. Results : Nine cases (69$\%$) showed residual symptom such as intermittent pain, insufficient recovery of muscle power, persistent muscle atrophy. Complete recovery in four cases (31$\%$). Mean value of ASES score was 86.4 (70-99.8) points. Postopertively, pain was relieved in 84$\%$ of patients and muscle power was improved in 53$\%$ of the patients but the atrophy persisted. Conclusions : Excision of ganglion is insuffient to relieve the nerve entrapment. Not only excision of ganglion but also treatment of intraarticular lesion, decompression of suprascapular and spinoglenoid notch which attributable to entrapment should be considered for the better clinical results.

Intracapsular chondromas of the knee have been reported rarely, so the authors report one case about its clinical and histologic findings. This is the case about 38-year-old man who feel painful swelling of the knee joint and the tenderness on the anterior aspect of knee. After arthroscopic excision, grossly there was a 2.5${\times}$l.5${\times}$1cm sized white colored firm mass which had central brownish lesion. Microscopically it was confirmed to chondroma which was consisted of hyaline cartilage and outer thinly synovial membrane.

Benign fibrous hitiocytoma of the infrapatella fat pad is very rare. It has usually do not induced a pain or a symptom because it was located deep tissue. So it was very difficult to be diagnosed. We experienced a case of deep benign fibrous histiocytoma in a 53-year-old woman. It was diagnosed by MRI. Diagnostic arthroscopic procedure was performed and the lesion was completely resected by open excision. We report a rare case of benign fibrous hitiocytoma presenting as an intra-articular tumor in the joint causing pain and limitation of movement.

Purpose: This study was designed to analyze the usefulness of Single Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) in diagnosing symptomatic accessory tarsal bones. Materials and Methods: Twenty four feet (16 patients) with symptomatic accessory navicular and/or os trigonum, who agreed to take SPECT/CT, were included in this study. Fifteen feet had accessory navicular, five had os trigonum, and four had both. According to the uptake in the SPECT/CT, 11 feet were classified into high and 13 into low uptake groups. The low uptake group was treated non-operatively, while the high uptake group received operations when initial conservative management failed. A modified Kidner procedure was performed for accessory navicular and arthroscopic excision was done for os trigonum. After a mean follow-up of 6.8 (range, 3~13) months, the American Orthopaedic Foot and Ankle Society (AOFAS) score and the Visual Analogue Scale (VAS) for pain were compared. Results: Patients in the high uptake group had a higher initial mean VAS score ($7.0{\pm}0.8$ vs $2.2{\pm}0.9$, p<0.05) and a lower initial mean AOFAS score ($45.9{\pm}9.2$ vs $83.9{\pm}4.2$, p<0.05) compared to the low uptake group. All patients in the low uptake group improved after non-operative treatment. Seven patients underwent operations and had a decreased VAS ($1.6{\pm}0.5$) and an increased AOFAS score ($88.3{\pm}1.8$) at the last follow-up. Four patients in the high uptake group demonstrated erratic symptoms. Conclusion: SPECT/CT can be a useful diagnostic tool and helpful in designing treatment plans for symptomatic accessory navicular and os trigonum.

Os acromiale is the rare shoulder disease and its treatment is controversial. Despite conservative treatments for 6 months include medication, exercise, physical therapy and subacromial steroid injections, operative treatment for uncontrolled symptomatic Os acromiale is considered the treatment of choice. Operative treatment includes excision, arthroscopic or open reduction and internal fixation with a bone graft. Open reduction with tension band wiring and a bone graft is now the preferred treatment. We experienced 8 patients with symptomatic Os acromiale from March, 2001 to March, 2006. The average patient's age was 45 years and the man and women ratio were 2: 6. All 8 cases of symptomatic Os acromiale of the mesoacromion were treated with open reduction and internal fixation using tension-band wiring. The preoperative ASES($47.3\pm24.4$) and UCLA ($16.6\pm5.8$)scores were improved to $88.8\pm7.3$ and $31.5\pm1.9$, respectively, at the 2 year follow up. The overall UCLA score showed 1 excellent result and 7 good results. We think that symptomatic Os acromiale is a specific disease entity, and open reduction and internal fixation using tension-band wiring with K-wire is a good treatment modality.
