Abstract
Background: The purpose of this study was to further delineate the outcome of arthroscopically assisted anterior cruciate ligament reconstruction in 1 25 patients who had previously been followed for two to five years. One of the original 125 patients was excluded from the present study because of in sufficient follow-up, and an additional group of 101 patients was added. Al l 225 patients in the present study were followed for a minimum of six year s. Methods: Patients were randomly assigned to reconstruction with a double-st randed semitendinosus-gracills graft with use of a two-incision technique ( group 1), reconstruction with a patellar ligament graft with use of a two-i ncision technique (group II), or reconstruction with a patellar ligament gr aft with use of a single-incision endoscopic technique (group III). The gro ups were compared with regard to the rate of graft failure, the amount of i nstability, knee strength, radiographic signs of degenerative changes, and functional outcome. Results: There was no significant difference among the three groups with re gard to the rate of graft failure, the amount of knee instability, or the f unctional outcome. A normal or nearly normal functional outcome was recorde d for 208 (92%) of the 225 patients. There were significant differences amo ng the groups with regard to quadriceps muscle-strength deficits: group I h ad fewer patients with deficits than group III, and groups I and III both h ad fewer patients with deficits than group II (p = 0.04). There also were s ignificant differences among the groups with regard to hamstring muscle-str ength deficits: group III had fewer patients with deficits than group II, a nd group II had fewer patients with deficits than group I (p < 0.01). Twelv e knees (16%) in group I, six knees (8%) in group II, and eight knees (11%) in group III showed radiographic evidence of progressive degenerative chan ges, but the differences among the three groups were not significant. Conclusion: Although 11.6% of the 225 knees had radiographic evidence of de generative arthritis at a minimum of six years after arthroscopically assis ted reconstruction of the anterior cruciate ligament, the choice of graft a nd the technique of reconstruction did not seem to affect the rate of devel opment of these changes.
