Arthroscopic treatment for localized pigmented villonodular synovitis of the knee
Clinical Orthopaedics and Related Research, 2000Co-Authors: Sungjae Kim, Sangjin Shin, Namhong Choi, Euitak ChooAbstract:This study investigated 11 patients with localized pigmented villonodular synovitis of the knee that was diagnosed and treated by Arthroscopic technique. There were six male and five female patients between the ages of 15 and 59 years (mean, 34.6 years). Seven patients reported extension limitation without joint line tenderness. Four of the 11 patients had a history of trauma before the onset of knee symptoms. All patients were treated by Arthroscopic Resection with partial synovectomy. The most common involved site was the anteromedial synovium near the anterior horn of the medial meniscus (five patients). The remaining cases were located in the anterior fat pad (two patients), suprapatellar pouch, posteromedial compartment, medial gutter, and the anterior horn of the lateral meniscus. Nine patients had one mass, and the remaining patients each had two or three masses. There was no evidence of recurrence at followup for an average of 29.9 months (range, 24-48 months). Arthroscopy is effective in the diagnosis of localized pigmented villonodular synovitis with minimal morbidity, and complete Arthroscopic excision can be considered the definitive treatment for localized pigmented villonodular synovitis.

Arthroscopic Resection for the unstable inferior leaf of anterior horn in the horizontal tear of a lateral meniscus
Arthroscopy, 2004Co-Authors: Sungjae Kim, Inseop ParkAbstract:The unstable inferior leaf of the anterior horn in the horizontal tear of the lateral meniscus is a challenging lesion to the arthroscopist. However, there are no devices for it and no proper procedures are introduced. We describe a new Arthroscopic technique of partial meniscectomy by using three portals. This technique uses a unique portal, extreme far anteromedially.

sonography guided arthroscopy for wrist ganglion
Journal of Hand Surgery (European Volume), 2012Co-Authors: Michiro Yamamoto, Shigeru Kurimoto, Nobuyuki Okui, Masahiro Tatebe, Takaaki Shinohara, Hitoshi HirataAbstract:Purpose To describe how to combine the complementary features of sonography and arthroscopy to make the Arthroscopic Resection of wrist ganglions a safer and more reliable surgery. Methods A total of 22 patients with wrist ganglions had sonography-assisted Arthroscopic Resection. Sonographic visualization of ganglions, adjacent structures (ie, vessels, nerves, and tendons), and the cycling tip of the Arthroscopic shaver was assessed. Arthroscopic visualization of the ganglions or ganglion stalk was also assessed. Clinical outcome measures included wrist range of motion, grip strength, and our patient-rated Hand 20 questionnaire. Results Sonographic visualization of the ganglion stalk, adjacent structures, and the cycling tip of the Arthroscopic shaver was possible in all 22 cases. However, ganglion stalks were visualized by arthroscopy in only 4 cases. The mean range of motion and grip strength were not significantly changed following surgery. However, the mean Hand 20 score was significantly improved from 17 to 6 at final follow-up. Ganglion recurrence was seen in 2 cases at 6 and 8 months after surgery. Conclusions Sonography-guided wrist arthroscopy provides several advantages for surgeons, including visualization of the ganglions and ganglion stalk, as well as of the Arthroscopic shaver and adjacent structures such as nerves, vessels, and tendons to perform surgery safely. Type of study/level of evidence Therapeutic IV.

Artroscopia da articulação escapulotorácica: relato de casos Arthroscopy of the scapulothoracic joint: case reports
Sociedade Brasileira de Ortopedia e Traumatologia, 2009Co-Authors: Carlos Vicente Andreoli, Benno Ejnisman, Alberto De Castro Pochini, Gustavo Cará Monteiro, Moisés Cohen, Flávio FaloppaAbstract:A artroscopia escapulotorácica é um procedimento que apresenta indicações restritas, para ressecção de corpos livres, tumores benignos, bursites e escápulas em ressalto. Os autores relatam quatro casos de artroscopia da articulação escapulotorácica; no primeiro caso, foi realizada apenas a visualização do tumor benigno (osteocondroma); no segundo caso, a ressecção artroscópica de um osteocondroma; no terceiro caso, a bursectomia artroscópica devido à bursite escapulotorácica; e no quarto caso, bursectomia e escapulectomia súpero-medial parcial artroscópica devido à escápula em ressalto.Scapulothoracic arthroscopy is a procedure presenting restricted indications, for resecting free bodies, benign tumors, bursitis, and snaping scapula. The authors report four cases of scapulothoracic joint arthroscopy; in the first case, only a benign tumor (osteochondroma) could be visualized; in the second case, Arthroscopic Resection of an osteochondroma was found; in the third case, Arthroscopic bursectomy due to scapulothoracic bursitis, and; in the fourth case, bursectomy and partial superomedial Arthroscopic scapulectomy due to snaping scapula

groin pain after open fai surgery the role of intraarticular adhesions
Clinical Orthopaedics and Related Research, 2009Co-Authors: Martin BeckAbstract:Femoroacetabular impingement (FAI) is an established cause of osteoarthrosis of the hip. Surgery is intended to remove the cause of impingement with hip dislocation and Resection of osseous prominences of the acetabular rim and of the femoral head-neck junction. Using the Merle d’Aubigne score and qualitative categories, recent studies suggest good to excellent outcomes in 75% to 80% of patients after open surgery with dislocation of the femoral head. Unsatisfactory outcome is mainly related to pain, located either in the area of the greater trochanter or in the groin. There are several reasons for persisting groin pain. Joint degeneration with joint space narrowing and/or osteophyte formation, insufficient correction of the acetabula, and femoral pathology are known factors for unsatisfactory outcome. Recently, intraarticular adhesions between the femoral neck and joint capsule have been identified as an additional cause of postoperative groin pain. The adhesions form between the joint capsule and the resected area on the femoral neck and may lead to soft tissue impingement. MR-arthrography is used for diagnosis and the adhesions can be treated successfully by arthroscopy. While Arthroscopic Resection improves outcome it is technically demanding. Avoiding the formation of adhesions is important and is perhaps best accomplished by passive motion exercises after the initial surgery.
