Eighty-seven patients have been examined 2 years on average after knee ligament reconstruction for a torn anterior cruciate ligament. The patients were divided into four groups according to the type of operation that had been carried out. In the first group an extra-articular lateral repair ("MacIntosh tenodesis") had been performed, in the second group an intra-articular "over-the-top" repair using the quadriceps and the patellar tendon, in the third group a modified "Eriksson" procedure using the patellar tendon, and in the fourth group a combined intra- and extra-articular repair using carbon fibres as a graft. The results of the operations in the different groups are compared. The best results were obtained with the "Eriksson" procedure, closely followed by the "over-the-top" repair. Limited range of motion and retropatellar pain resulting from changes in the alignment of the patella were the main problems. The results after the use of carbon fibres were less good. In two cases the graft tore without further trauma, and there were also problems because of restricted range of motion and retropatellar pain. The worst results were found after extra-articular lateral repair, due to insufficient stability in many cases. However, the best results with regard to the range of motion were found in this group.
