PURPOSE: The aim of this study was to evaluate the outcome of arthroscopic partial repair and margin convergence of irreparable large to massive rotator cuff tears. METHODS: Between January 2003 and July 2008, 27 patients who met the inclusion criteria underwent arthroscopic partial repair and margin convergence of irreparable large to massive rotator cuff tears. An irreparable tear was defined as a tear with a minimum anterior-to-posterior width of 3 cm or larger, where it was not feasible to c

The complete repair group with an aggressive release had no better clinical or structural outcomes compared with the partial repair group with margin convergence alone for large-to-massive contracted rotator cuff tears. In addition, the complete repair group had a 91% retear rate and a greater defect on follow-up MRA images. Even though this study had a relatively short-term follow-up, a complete repair of large-to-massive contracted rotator cuff tears, with an aggressive release such as posteri

We present the operative technique and clinical results of concomitant reconstruction of the medial collateral ligament (MCL) and the posterior oblique ligament for medial instability of the knee using autogenous semitendinosus tendon with preservation of the tibial attachment. The semitendinosus tendon graft between the screw on the medial epicondyle and the tibial attachment of the graft was overlapped by the MCL, while the graft between the screw and the insertion of the direct head of the se

This study describes the long-term clinical results and serial changes of postoperative range of motion after arthroscopic treatment for limitation of motion of the elbow. Sixty-three patients with limitation of motion of the elbow were treated with arthroscopic procedures. The total range of motion was 79 degrees before surgery. The range of motion showed a progressive increase until 1 year after surgery (mean, 121 degrees). However, after 1 year, the range of motion showed little additional in

In 147 patients with arthroscopically proved chronic injuries of the anterior cruciate ligament, the anterior drawer test, the Lachman test, and the pivot shift test were done before operation under general or spinal anesthesia. Results of the anterior drawer test were positive in 79.6% of the patients, in 98.6% patients having the Lachman test, and in 89.8% of patients having the pivot shift test. In 19 cases (12.9%), arthroscopic examination showed reattachment of the proximally torn end of th

PURPOSE: The purpose of this study was to evaluate and compare postoperative anterior knee pain, knee stability, and functional scores of an autogenous bone-patellar tendon-bone (BPTB) graft and a quadriceps tendon-bone (QTB) graft. METHODS: A total of 48 patients--27 who had anterior cruciate ligament (ACL) reconstruction by use of an autogenous BPTB graft and 21 who had ACL reconstruction by use of a QTB graft--were assessed at a minimum follow-up of 24 months after surgery. An accelerated reh

Twenty-five patients with limitation of motion of the elbow joint caused by the intraarticular pathologies were treated with the following arthroscopic procedures: removal of loose bodies, excision of osteophytes, anterior capsular release, abrasion arthroplasty, and partial excision of the radial head. The extension of the elbow improved by 7 degrees, from a preoperative average of 21 degrees to a postoperative average of 14 degrees. The flexion of the elbow improved by 17 degrees, from a preop

Arthroscopic procedures can be used to treat tibial avulsion fractures of the posterior cruciate ligament.

BACKGROUND: Despite its technical complexity, arthroscopic tibial inlay reconstruction of the posterior cruciate ligament has biomechanical advantages over transtibial procedures. The purpose of this study was to compare the clinical results of arthroscopic tibial inlay single-bundle and double-bundle techniques with those of the conventional transtibial single-bundle technique. METHODS: We evaluated twenty-nine patients treated with primary posterior cruciate ligament reconstruction and followe

From June 1991 to March 1993, 400 knees in 363 patients were studied arthroscopically to clarify the arthroscopic anatomy of the plica and determine the classification of the plica. The various patterns of the synovial plicae were classified according to their shape and size from the arthroscopic view. Incidences of the synovial plica at the knees were: suprapatellar plica, 87.0%; mediopatellar plica, 72.0%; infrapatellar plica, 86.0%; and lateral patellar plica, 1.3%. There was no significant c

From July 1990 through June 1994, 106 knees (102 patients) were treated for discoid meniscus. Fifteen knees (15 patients) were associated with other intraarticular anatomic variants. There were eight knees (8 patients) with anomalous insertion of the anterior horn of the medial meniscus into the anterior cruciate ligament, and seven knees (7 patients) with anterior expansion of the anterior portion of the anterior cruciate ligament below the anterior tibial margin. Among the latter, one patient

Arthroscopic debridement and drainage was done in 10 patients with septic arthritis of the hip. Staphylococcus aureus was the most commonly identified organism. All patients were placed in the supine position on a fracture table and three arthroscopic portals were used during the procedure. No major complication related to the arthroscopy of the hip resulted. The average followup was 4 years 11 months. All patients had excellent results.

Twenty patients underwent operative arthroscopic procedures of the hip joint. All procedures were performed with the patient in the supine position on a standard fracture table using fluoroscopy through three arthroscopic portals (anterolateral, anterior paratrochanteric, and posterior paratrochanteric). The initial indications were therapeutic in 16 patients: loose bodies in four, synovial chondromatosis in three, rheumatoid arthritis in five, ankylosing spondylitis in one, septic arthritis in

High tibial osteotomy is a realignment procedure to transfer weight-bearing load to the intact compartment of the knee to alleviate symptoms, slow disease progression, and defer subsequent total knee arthroplasty. To prevent overcorrection or undercorrection, it is not only important to have an exact preoperative calculation of the desired correction angle, but it is also critical to have an accurate intraoperative technique. 85 consecutive patients (90 knees) were enrolled, who were available a

This study compared the long-term clinical and radiological outcomes, according to the extent of arthroscopic meniscectomy, of complete and incomplete types of the discoid lateral meniscus. A total of 125 discoid menisci (74 complete and 51 incomplete types) without significant cartilage erosion at the time of surgery were included. The extent of meniscectomy was decided along with tear patterns and the stability of the discoid meniscus. Both clinical and radiological results were evaluated afte
