| pubmed-article:8465914 | pubmed:abstractText | One hundred eighty-seven patients who had undergone intraarticular anterior cruciate ligament reconstruction using either a fresh-frozen allogeneic tendon or central third autogenous pateller tendon 3 to 89 months previously were arthroscopically evaluated. The focus was on secondary changes of the patellofemoral joint at the time of second-look arthroscopy. Overall, 93 knees deteriorated, 74 knees remained unchanged, and 14 improved. The deteriorative changes were predominantly located around the central ridge of the patellae, although all but two knees remained free from anterior knee pain. Statistical multivariate analysis showed surgical approach by conventional medial parapatellar incision and use of the central one-third of the autogenous patellar tendon graft as possible risk factors for the deterioration, although chi-square analysis failed to demonstrate statistical significance for the latter. | lld:pubmed |
