Abstract
BACKGROUND: Arthroscopic anterior cruciate ligament (ACL) reconstruction is a common orthopedic procedure. Most of the literature is on high-demand athletic patients, with little information about the outcomes of low-demand patients. Therefore, we aim to assess the outcomes of non-athletic patients following home-based rehabilitation. METHODS: An observational cross-sectional comparative study was conducted with 30 non-athletic adults with ACL injuries whose pre-injury Tegner activity level was four or less. After six months of reconstruction, patients were assessed for functional outcomes using the Tegner activity level, Lysholm score, International Knee Documentation Committee (IKDC) score, and ACL quality of life (QOL) score. Functional performance was assessed by the carioca test, one-leg hop test, and shuttle test. Functional outcome and performance were compared with an age, sex, and activity level-matched group. Knee stability was assessed by Lachman, anterior drawer, and pivot shift. RESULTS: All patients returned to their pre-injury Tegner activity level. A statistically significant difference was seen in the Lysholm score, IKDC score, ACL QOL score, carioca test, shuttle test, and one leg hop test (p= <0.001 in each); >5mm of translation of the tibia in the Lachman test was seen in three patients, whereas one patient had >5 mm of translation in the anterior drawer test but pivot shift was absent in all. CONCLUSION: We found that all patients returned to their pre-injury Tegner activity level. Most patients had improved knee stability; however, functional outcomes and performance were lower compared to the control group. Therefore, arthroscopic ACL reconstruction is a reasonable treatment option for non-athletic, low-demand patients to get back to their pre-injury functional activity level.
