STUDY DESIGN Prospective cohort study without a control group
OBJECTIVES Firstly to present our 5 week progressive exercise therapy program in the early stage after anterior cruciate ligament (ACL) injury Secondly to evaluate changes in knee function after completion of the program for patients with ACL injury in general and also when classified as potential copers or noncopers and finally to examine potential adverse events
BACKGROUND Few studies concerning early stage ACL rehabilitation protocols exist Con sequently little is known about the tolerance for and outcomes from short term exercise therapy programs in the early stage after injury
METHODS One hundred patients were included in a 5 week progressive exercise therapy program within 3 months after injury Knee function before and after completion of the program was evaluated from isokinetic quadriceps and hamstrings muscle strength tests 4 single leg hop tests 2 different self assessment questionnaires and a global rating of knee function A 2 way mixed model analysis of variance was conducted to evaluate changes from pretest to posttest for the limb symmetry index for muscle strength and single leg hop tests and the change in scores for the patient reported questionnaires In addition absolute values and the standardized response mean for muscle strength and single leg hop tests were calculated at pretest and posttest for the injured and uninjured limb Adverse events during the 5 week period were recorded
RESULTS The progressive 5 week exercise therapy program led to significant improvements (P< 05) in knee function from pretest to posttest both for patients classified as potential copers and noncopers Standardized response mean values for changes in muscle strength and single leg hop performance from pretest to posttest for the injured limb were moderate to strong (0 49 0 84) indicating the observed improvements to be clinically relevant Adverse events occurred in 3 9% of the patients
CONCLUSION Short term progressive exercise therapy programs are well tolerated and should be incorporated in early stage ACL rehabilitation either to improve knee function before ACL reconstruction or as a first step in further nonoperative management
