Anterior cruciate ligament reconstruction in patients over 50 years of age

To describe the clinical outcomes of patients over 50 years of age with following anterior cruciate ligament (ACL)reconstruction for acute rupture.

A prospective series of patients over the age of 50 years with a diagnosis of ACL rupture who underwent ACL reconstruction was examined. Lysholm and International Knee Documenting Committee (IKDC) subjective scores were assessed preoperatively and at the final follow-up. All associated injuries were documented, and complications were reported. The patients' satisfaction and return to sports were documented. The statistical analyses were preformed with Student's t-tests for independent samples.

Fifty patients with a mean age of 52.12 years (50-64) and a mean follow-up period of 53.17 months (36-68) exhibited a mean postoperative Lysholm score of 93.7 (60-100) and IKDC score of 90.96 (57.5-100). Associated injuries occurred in 90% (45) of the patients and included the following: 76% (38) meniscal tears and 36% (18) osteochondral lesions. Complications occurred in 6% (3) of the patients and included the following: 4% (2) ACL re-ruptures and 2% (1) infections. Among all patients, 88% (44) returned to pre-injury sports levels, and 96% (48) were satisfied.

For patients above the age of 50 years, ACL reconstruction appears to be a safe procedure with good to excellent results that are comparable to those for younger patients, and the possibility for returning to pre-injury sports levels for these patients is high.
