Abstract
31 consecutive patients (mean 54.7 years) were examined mean follow-up time of 47 months. Patients were evaluated clinically; using Lysholm, Cincinnati, IKDC and Tegner Activities Scores. Objective assessments were made with KT1000 Arthrometer and Isokinetic strength testing.
Lysholm scores improved from 62 preoperatively to 93 at review; Cincinnati 48 to 89; Tegner 3.6 to 5.2. 81 percent of knees were considered normal or nearly normal to IKDC, 6 abnormal, none severely abnormal. KT1000 manual max difference 2.9mm; Isokinetic flexion strength 102 percent; extension strength 95 percent. Poor results were mainly associated with advanced articular cartilage degenerative changes at time of surgery. This also correlated with increased time from injury to surgery, and increased preoperative injury rates.
This study demonstrates that the anterior cruciate ligament can be reliably reconstructed in patients over the age of 50 years with good symptomatic relief, restoration of function and return to activity.
