- Abstract
- OBJECTIVE: To study muscle strength and functional performance in patients with anterior cruciate ligament (ACL) injury with or without surgical reconstruction 2 to 5 years after injury. Good muscle function is important in preventing early-onset osteoarthritis (OA), but the role of reconstructive surgery in restoring muscle function is unclear. METHODS: Of 121 patients with ACL injury included in a randomized controlled trial on training and surgical reconstruction versus training only (the Knee, Anterior cruciate ligament, NON-surgical versus surgical treatment [KANON] study, ISRCTN: 84752559), 54 (mean age at followup 30 years, range 20-39, 28% women) were assessed a mean +/- SD of 3 +/- 0.9 years after injury with reliable, valid, and...

The Limb Symmetry Index (LSI; injured leg divided by uninjured and multiplied by 100) value and absolute values were used for comparisons between groups (analysis of variance). An LSI >/=90% was considered normal. RESULTS: There were no differences between the surgical and nonsurgical treatment groups in muscle strength or functional performance. Between 44% and 89% of subjects had normal muscle function in the single tests, and between 44% and 56% had normal function in the test batteries. CONCLUSION: The lack of differences between patients treated with training and surgical reconstruction or training only indicates that reconstructive surgery is not a prerequisite for restoring muscle function. Abnormal muscle function, found in approximately one-third or more of the patients, may be a predictor of future knee OA. (Less)
