Abstract:
Between August 1994 and June 1995, seventeen patients diagnosed as having partial or complete ruptures of the anterior cruciate ligament on MRI were managed by non-operative methods. Among them four patients were excluded due to operation during follow-up and the results were evaluated at a one year follow-up. We selected the patients prospectively for non-operative care using the selection criteria of age, degree of instability, activity level and patient compliance. The average age of them was 37.7 years. Initially knee stress test and MRI were checked, and Cybex study and Lysholm knee scoring were done at post-trauma one year follow-up. They were managed conservatively by ROM and muscle strengthening exercises and a brace fitting schedule for three months. Among them, six cases had partial tears and seven had a complete tear initially. At the one year follow-up, five of six cases who had shown partial ruptures, and two of seven cases with complete tears, recovered continuity of the ruptured ACL on MRI. Their Lysholm knee score was 84.4, and the Cybex test showed no difference in muscle power between the injured and uninjuried side. Those patients who had loss of continuity on follow-up MRI showed Lysholm score of 57.4 and decreased muscle power on Cybex study. Although there are still controversies about the adequate management of ACL injuries, our study suggests that conservative management is a viable alternative to surgery as long as the patients are selected prudently. For more concrete results, however, careful analysis based on a longer follow up period is necessary.
