Sports capacity after rupture of the anterior cruciate ligament--surgical versus non-surgical therapy

Using a new rating system (Innsbruck Knee-Sports Rating Scale) 75 patients 5 to 6 years after ACL-injury have been compared to their sports activity (47 patients with ACL reconstruction and 28 conservative treated patients). Under the viewpoint of knee load and especially the demand on stability sports activities have been divided into 3 categories: High Risk, Low Risk and Non Risk Pivoting Sports. Operative therapy shows an advantage in High Risk Pivoting sports (e.g. soccer, basketball) and in Low Risk Pivoting (e.g. running, hiking) sports, expressed by fewer knee related symptoms and higher participation levels. In the Non Risk Pivoting category (e.g. swimming, cycling) good results could also be achieved by conservative therapy. The careful evaluation of each patient's sports activities is therefore an important factor in the decision for the right therapy on one hand, and for comparing the results of different therapy programs or patient collectives on the other.
