Abstract

BACKGROUND:

The choice of graft material for anterior cruciate ligament reconstruction is believed to play a major role in outcome, but most comparisons of graft choice have not been well controlled.

HYPOTHESIS:

The choice of graft material (patellar tendon or hamstring tendon) does affect clinical outcome after anterior cruciate ligament reconstruction.

STUDY DESIGN:

Prospective, nonrandomized clinical trial.

METHODS:

Two groups of 90 patients each were followed for a minimum of 5 years.

RESULTS:

International Knee Documentation Committee assessment revealed that more than 85% of each group had an overall score of A or B at all follow-up intervals. The median Lysholm knee score was greater than 90 for both groups at 2 and 5 years. Instrumented testing revealed no significant difference between the two groups beyond 3 years. Thirty-one percent of the patellar tendon group (25) had a fixed flexion deformity and 19% of the hamstring tendon group (14) had fixed flexion deformity at 5 years. Radiologic assessment revealed early osteoarthritic changes in 4% of the hamstring tendon group (2) and in 18% of the patellar tendon group (11) at 5 years.

CONCLUSIONS:

Arthroscopic reconstruction with either graft results in a similar surgical outcome, reliably restoring knee stability over a 5-year period; however, patients with patellar tendon grafts are at greater risk of developing early signs of osteoarthritis.
