Abstract

Twenty-five patients with arthroscopically proven partial ACL tears were reviewed. All patients underwent examination under anesthesia and arthroscopy following an acute injury to a previously normal knee. The percentage of tear was estimated during arthroscopy. Postoperatively, patients were treated with early motion and hamstring strengthening. Weightbearing and quadriceps rehabilitation were delayed. A detailed rating of symptoms and function was performed at a minimum of 18 months after injury, using a modification of the AOSSM ACL follow-up form. Neither the estimated percentage of ligament tear, length of followup, nor age at time of injury significantly correlated with clinical score at followup. Thirteen patients underwent partial meniscectomy at the time of original arthroscopy. Their clinical outcome was not different from those without meniscectomy. Two patients (8%) underwent ACL reconstruction 8 and 64 months after injury, respectively. Overall results were judged as excellent (28%), good (32%), fair (24%), and poor (16%). Only 44% were able to resume sports at their preinjury level, and 72% had activity-related symptoms.
