Medial meniscus anterior horn cyst: arthroscopic decompression.

Meniscus cysts are mostly seen with meniscus tears, and arthroscopic decompression of cysts is gaining great importance in their treatment. In this study, we present a medial meniscus anterior horn cyst without an accompanying tear in the meniscus. A 33-year-old male patient was seen with pain and a palpable mass in his right knee. He complained that the severity of the pain had increased over the previous year. After the clinical and radiologic examinations, a painless, fixed soft tissue mass averaging 4 x 5 cm was located just medial to tuberositas tibia. The cyst was decompressed arthroscopically. In the 18th month of follow up, the mass had totally disappeared and the patient had no pain. Medial meniscus cysts are seen nine times fewer than lateral meniscus cysts. They are mostly accompanied with meniscal tears. Total meniscectomy with arthrotomy, isolated cyst excision, cyst excision, and partial meniscectomy with arthrotomy and arthroscopic partial meniscectomy with cyst decompression are treatment modalities. Arthroscopic meniscal cyst decompression is an important treatment choice and should always be taken into consideration with low morbidity, short recovery period, low recurrence rate, preservation of range of motion, and permission for early mobilization and rehabilitation of the joint.

[Defective forearm pseudoarthrosis with a neglected elbow dislocation].

Neglected elbow dislocations, rarely seen in the developed countries, are very attractive due to the difficulties of treatment and diversity of prognosis. A 32 year-old woman was admitted with chronic elbow dislocation and defective forearm pseudoarthrosis due to an accident four months prior to admission. Open reduction and distraction arthroplasty using hinged external fixator for the elbow, open reduction and internal fixation with plate-screws with fibula allograft for the forearm was performed. The elbow was stable and had 110 degrees and -15 degrees of active flexion and extension respectively on the ninth month of follow-up. Both radius and ulna were united.

Central third bone-patellar tendon-bone arthroscopic anterior cruciate ligament reconstruction: a 4-year follow-up.

This prospective study reports the 4-year follow-up results of 56 patients (44 males and 12 females) who underwent arthroscopic reconstruction of the anterior cruciate ligament (ACL) using a central third bone-patellar tendon-bone free autologous graft and assesses the mid-term effectiveness of this technique. Mean patient age was 30.2 years (range: 17-44 years). Sports injuries were the primary cause of ACL deficiency in 93% of patients. All knees had an isolated ACL tear, and 31 had associated meniscal or chondral lesions. Patients in the acute phase did not undergo surgery for 3-4 weeks. In patients with subacute and chronic ACL ruptures, the mean interval between injury and surgery was 62 weeks (range: 8-104 weeks). According to the International Knee Documentation Committee grading system, 53 (95%) knees were considered normal or nearly normal postoperatively. Improvement by at least 1 grade was noted in 12 knees, 30 knees had an improvement of at least 2 grades, 12 knees had a 3-grade improvement, and 1 had a grade that remained unchanged. One knee deteriorated from a grade C to a grade D, which was attributed to graft lysis 1 year postoperatively. For best results, subacute reconstruction between 3 and 5 weeks postinjury is recommended.

[Total knee arthroplasty: a 4.5-year follow-up].

OBJECTIVES: To present the short- and mid-term follow-up results of primary total knee arthroplasty. METHODS: We performed a total of 97 cemented total knee replacements (47 right, 50 left) with posterior cruciate ligament retention in 66 patients (60 women, 6 men). The mean age at the time of surgery was 65.2 years (range 29 to 82 years). Preoperative diagnoses were primary osteoarthrosis (n=60), rheumatoid arthritis (n=3), systemic lupus erythematosus (n=2), and post-traumatic osteoarthritis (n=1). Thirty-one patients had bilateral knee replacements, of which 29 were performed at the same session. Pre- and postoperative clinical evaluations were made according to the clinical rating system of the Knee Society. Radiographic evaluations were made according to the Fairbank's criteria preoperatively, and to the total knee arthroplasty radiographic evaluation and scoring system of the Knee Society postoperatively. The mean follow-up was 4.5 years (range 24 to 98 months). RESULTS: Clinical results were good or excellent in 94.8 percent of patients. Complications encountered were deep infection in two patients, patellar dislocation in two patients, deep venous thrombosis in two patients, and patellar tendon rupture in one patient. The mean increases in knee and functional scores were 42.94 and 39.87, respectively. Improvement in the mean postoperative knee flexion was 35.72 degrees. The mean leg alignment was 6.3 degrees valgus. No components required revision because of aseptic loosening. CONCLUSION: Posterior cruciate ligament retaining implants were found to yield successful clinical and radiologic results during short- and mid-term follow-up period.
