Purpose: We introduce a technique of all inside arthroscopic capsular imbrication and lateral release used to treat patellofemoral instability. Methods: With the arthroscope in the anteromedial portal for best viewing, the arthroscopic scissor is placed through superolateral portal for proximal to distal release. The release performed 5mm to 1cm from the edge of the patella. After completion of the procedure, with the arthroscope in anterolateral portal, we inserted 5mm cannula in superolateral portal and made working portal from superomedial portal. Medial reefing was performed with all inside technique by using curved needle of the spectrum suturing system and No. 1 monofilament PDS suture is passed through the superomedial portal percutaneously and retrieved through a superolateral portal. Conclusion: Several methods for arthroscopic patella realignment have been proposed, but they have consisted primarily of arthroscopically assisted techniques using a medial incision. We believe that our procedure is preferable to arthroscopically assisted methods commonly used, in that an incision is avoided and the vastus medialis obliqqus is not violated. Our technique is minimally invasive and is easy to control the tightness of the medial patellofemoral ligament (MPFL) under direct vision.

Purpose: The objective of this study was to assess the clinical outcome of arthroscopic release of the extensor carpi radialis brevis (ECRB) tendon in chronic recalcitrant lateral epicondylitis and tried to determine any prognostic factors. Materials and Methods: A retrospective review of 24 patients with lateral epicondylitis treated by arthroscopic ECRB release was performed. Outcome measures included a patient self rating and visual analog scale (VAS). Functional evaluation was made with Quick-disabilities of the arm, shoulder and hand (DASH) score system to identify preoperative factors that might be associated with the outcomes. Results: Twenty one (88%) elbows received benefit from the procedure. A mean preoperative VAS pain score and the mean Quick-DASH were significantly improved at final follow up. Age, sex, dominant arm and duration of symptom, presence of capsular tear or calcification did not correlate significantly with the clinical outcome. Three of four patients without T2-weighted high signal focus of the ECRB origin on preoperative magnetic resonance imaging (MRI) showed higher Quick-DASH score. Conclusion: Arthroscopic release of the ECRB is an effective option for chronic recalcitrant lateral epicondylitis. Lack of high signal focus on preoperative MRI is significantly associated with a poor surgical outcome and a considerable factor for the proper surgical indication.

Purpose: We assessed the clinical results after the operative treatment of type 2 SLAP lesion with stiffness. Materials and Methods: 13 patients who had SLAP lesion with stiffness were treated with arthroscopic capsular release, SLAP repair and treatment of the associated lesion. The average follow-up period was above 12 months. Results: The postoperative mean VAS was scored 1.5 and the postoperative ROWE score was 92.3, which showed a significant improvement after the operation (P<0.001). The mean range of motion was a significantly improved after the operation (P<0.001). The ROWE score was excellent for all the cases. Conclusion: Arthroscopic capsular release and SLAP repair and treatment of the associated lesion in patients with type 2 SLAP lesion with stiffness are effective treatments for the increasing the range of motion and decreasing the pain.

We retrospectively reviewed the results of arthroscopic adhesiolysis on postoperative knee stiffness in order to observe the clinical improvement and to evaluate the prognostic factors. Arthroscopic adhesiolysis without extraarticular procedure was performed in 31 knees displaying persistent flexion or extension loss. The causes of arthrofobrosis were previous ligament surgeries in 17 knees, surgery for a fracture involving the articular surface of the knee in 10 cases and other causes in four cases. The average range of motion was $60^{\circ}(range,\;14^{\circ}-74^{\circ})$ preoperatively, and improved by $120^{\circ}(range,\;7^{\circ}-127^{\circ})$ immediately following the procedure. The range of motion at the final follow-up (average 34 months) was $129^{\circ}(range,\;3^{\circ}-132^{\circ})$. In the 17 patients with arthrofibrosis fellowing ligament surgery, the range of motion was improved from $65^{\circ}$ preoperatively to $135^{\circ}$ at final follow-up. The improvement in function and motion was achieved during the first postoperative year. In the 10 patients with arthrofibosis following intraarticular fractures, the range of motion was improved from $60^{\circ}$ preoperatively to $125^{\circ}$ at the final follow-up, and most of the increase in motion was achieved within the first 6 months. Patients who suffered from a limitation of motion for less than 7 months gained an average $70^{\circ}$ improvement in total range of motion following arthroscopic surgery. However, the total range of motion in patients with a duration of symptoms greater than 7 months improved by an average $49^{\circ}$ postoperatively. In conclusion, arthroscopic adhesiolysis without incisional procedure is an effective therapeutic modality in arthrofibrosis of intraarticular origin. Improved outcomes can be expected in stiffness after ligament surgery and a symptom duration of arthrofibrosis less than 7 months.

Purpose: Management of the stiff elbow by arthroscopic procedure is an effective but technically demanding. Our purpose was to review the specific arthroscopic maneuver which can be useful for the stiff elbow. Materials and Methods: A stiff elbow that is refractory to conservative treatment can be treated surgically to remove soft tissue or bony blocks to motion. The olecranon or coronoid osteophyte and loose bodies have been removed arthroscopically with good results and rare complications. Results and Conclusion: For the successful arthroscopic management of elbow stiffness, it need to knowledge and skills for debride contracted tissue and preserve vital anatomic structure.

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.

Meniscal ossicle in the knee is very rare disease and is important to distinguish with loose body. We experienced a case of meniscal ossicle that had knee joint pain and clicking on standing up and met with a good result with arthroscopic meniscectomy. Therefore, we report this case with a review of relevant literature.
