Non-operative management of anterior cruciate ligament injuries pn the general population

The operative treatment of lesions of the anterior cruciate ligament (ACL) in athletes has been widely advocated and performed. We have investigated the outcome of non-operative management in a lower-demand, general population, We reviewed a consecutive group of 228 patients, which excluded professional and high-level athletes, for two to 12 Sears after an ACL lesion had been diagnosed by arthroscopy. There was a low incidence of secondary ACL and meniscal surgery, 5.4% and 3.5% respectively, and all these procedures were performed during the first three years after the ACL injury. We studied a subgroup of 109 patients with follow-up of at least five Sears (mean 8.5 years) and evaluated them using the IKDC score, The general outcome was reasonably satisfactory with 23% in grade A, 50% in grade B, 21% in grade C and only 6.4% in grade D. We found no statistically significant prognostic effect within this group as regards age, activity levels, or the incidence of associated lesions.
