The prevalence of gonarthrosis and its relation to meniscectomy in former soccer players.

The prevalence of radiographic signs of gonarthrosis and its relation to knee injuries were studied in 286 former soccer players--215 nonelite and 71 elite players--and were compared with 572 age-matched controls with a mean age of 55 years. The prevalence of gonarthrosis among the nonelite players was 4.2%, among the elite players 15.5%, and among the controls 1.6%. Seven of the soccer players had known anterior cruciate ligament injuries, and 40 had had meniscectomies. Of the 32 nonelite players with knee injuries, 4 (13%) had gonarthrosis, and of the 183 without known knee injuries 5 (3%) had gonarthrosis. Among the elite players, the prevalence of gonarthrosis in knees without diagnosed injuries was 11%. We conclude that soccer, especially at an advanced level, is associated with an increased risk for gonarthrosis. After excluding subjects with known knee injuries, there was no difference between nonelite players and controls, but we found a higher rate of gonarthrosis among the elite players.

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). However, the specificity of magnetic resonance imaging was only 29% and 27% for the lateral and medial menisci, respectively, and the accuracy was 28% and 50%, respectively. Marrow edemas, or bone bruises, were seen on magnetic resonance imaging in 80% of the patients and were mainly seen in the lateral compartment. Bone scans correlated well with magnetic resonance imaging findings of marrow edemas. Plain radiographs were normal in all but one case. We show that magnetic resonance imaging does not add information on the status of the anterior cruciate ligament compared with the clinical examination, and that it may be as good as arthroscopic evaluation for the diagnosis of meniscal tears that require surgery.
