摘要Introduction: Quadriceps muscle atrophy after anterior cruciate ligament reconstruction (ACLR) is well documented. Athletes are one of the high-risk groups for vitamin D deficiency. Vitamin D deficiency can potentially result in decreased hypertrophy in response to rehabilitation, leading to a poorer outcome. Vitamin D has been recognised for its effect on musculoskeletal health. The aim of the study is to determine the role of vitamin D deficiencies on quadriceps muscle atrophy in ACLR patients.
Methods: Vitamin D levels were measured in patients after ACLR. Patients undergoing a unilateral ACLR with hamstring graft were recruited for the study. Quadriceps thicknesses and isokinetic strengths were recorded. Blood samples for the 25-OH vitamin D serum concentrations were measured by ELISA. Knee function questionnaires were recorded.
Results: Sixteen participants were recruited for the study. Cluster analysis resulted in 9 non-atrophic and 7 atrophic patients, 30% strength deficits were observed in the atrophy group and 20% strength deficits were observed in the nonatrophy group. 68% of the patients were found to have vitamin D insufficiencies with levels below 30 ng/ml, 56% had deficiencies with levels below 20 ng/ml. Patients with vitamin D deficiency showed to have a lower quadriceps muscle thickness and lower IKDC. Regression analysis suggested that quadriceps strength in involved side and vitamin D deficiency status accounted for variations in IKDC.
Discussion and Conclusion: We demonstrated an association between vitamin D deficiencies and quadriceps muscle atrophy with lower IKDC in ACLR patients. These data may support the role vitamin D supplementation to enhance functional recovery in ACLR.
