Total meniscectomy in adolescence. A thirty-year follow-up.

We have carried out a prospective, longitudinal 30-year review of 95 adolescents who underwent total meniscectomy in one knee, and have compared the results with those observed 13 years earlier. All the medical records were scrutinised. Of the 63 patients reviewed clinically, 47 reported decreased sporting activity, although subjective satisfaction rose by 3% to 71%.

Meniscal regeneration in the long-term after total meniscectomy?

A cohort of 39 patients (28 male, 11 female) that had undergone total meniscectomy as adolescents (mean age 16 years) underwent FISP 3D Magnetic Resonance Imaging at a mean follow up of 30 years. The presence of meniscal tissue was assessed by two independent observers blinded to the operation details. The volume of any meniscal tissue present was calculated.

Knee osteoarthritis after meniscectomy: prevalence of radiographic changes after twenty-one years, compared with matched controls.

Objective: To study the long-term outcome of surgical removal of a meniscus in the knee with regard to radiographic signs of osteoarthritis (OA).

Methods: Of the 123 patients who underwent an open meniscectomy due to an isolated meniscus tear in 1973 at Lund University Hospital, 107 were followed up 21 years later by clinical examination and by review of knee radiographs obtained with weight bearing. Seventy-nine of the 107 patients were men, and the mean age of the total study group at examination was 55 years (range 35-77).

Magnetic resonance imaging, scintigraphy, and arthroscopic evaluation of traumatic hemarthrosis of the knee.

Forty patients with traumatic knee hemarthrosis were examined within 1 week after injury and observations made with magnetic resonance imaging, scintigraphy, arthroscopic evaluation, radiography, and physical examination were compared. Thirty-four patients (85%) had anterior cruciate ligament injuries according to the arthroscopic findings and 28 (83%) of these had associated meniscal tears. Magnetic resonance imaging confirmed the arthroscopic findings, especially if only meniscal tears that required surgery were taken into account (sensitivity, 94% for the lateral and 83% for the medial meniscus).

Osteoarthritis of the knee after injury to the anterior cruciate ligament or meniscus: the influence of time and age.

The degree of cartilage changes by arthroscopic and radiologic examination was evaluated in a retrospective, cross-sectional study of 1012 patients with knee complaints at different times after knee injury. Patients were classified by age, sex, trauma date and type of injury. The condition of the cartilage was graded on a 1-10 scale based on findings at arthroscopy and on weight-bearing radiographs.
