Early Accelerated versus Delayed Conservative Rehabilitation Protocol after Anterior Cruciate Ligament Reconstruction: A Prospective Randomized Trial.

Objective  To compare the effectiveness of the early accelerated rehabilitation and delayed conservative rehabilitation protocols after arthroscopic anterior cruciate ligament reconstruction, in terms of the International Knee Documentation Committee (IKDC) score, pain (according to the Visual Analog Scale), laxity, and stiffness one year postoperatively to determine the best outcome. Materials and Methods  A total of 80 subjects were divided into 2e groups (early accelerated group and delayed conservative group), which were analyzed by the Pearson Chi-squared and Wilcoxon rank-sum tests. Results  One year postoperatively, knee laxity was significantly higher ( p  = 0.039) in the early accelerated group compared with the delayed conservative group. Regarding postoperative pain (according to the Visual Analogue Scale) and IKDC scores, both groups presented similar results. The postoperative range of motion was better in the early accelerated group, but this was not statistically significant ( p  = 0.36). Conclusion  One year postoperatively, the early accelerated rehabilitation protocol was associated with significant knee laxity compared to the delayed conservative rehabilitation protocol.
