BACKGROUND: No consensus is obtained regarding the effects of remnant-preserving ACL reconstruction on long-term clinical and proprioceptive outcomes. This study aimed to compare proprioceptive and clinical outcomes of the knee joint after ACL reconstruction with two different lengths of preserved remnant tissue.
METHODS: This study included 61 patients who underwent single-bundle ACL reconstruction with remnant preservation method using hamstring autograft, divided into two groups according to the length of the remnant tissue. Group ≤33% included subjects with equal and less than 1/3 of the remnant preserved (n = 30) and group >33% included subjects with more than 1/3 of the remnant preserved (n = 31). Proprioception was evaluated at 20°, 50°, and 70° knee angles. Clinical outcome measures included Tegner activity scale, Lysholm knee score, single-leg-hop test, and muscle strength of quadriceps femoris and hamstring muscles which was evaluated using Biodex dynamometer. Anterior laxity was determined with a KT2000 arthrometer. A statistical comparison of the assessments was performed.
RESULTS: The mean follow-up time after surgery were 28.33 and 33.67 months for group ≤33% and >33%, respectively. No significant differences were detected for Lysholm and Tegner scores between the groups (p > 0.05). Additionally, proprioception and muscle strength values displayed similarity between the groups (p > 0.05). The length of the remnant tissue did not affect post-operative knee stability (p > 0.05).
CONCLUSION: Patients who underwent remnant-preserving ACL reconstruction obtained similar proprioceptive function, muscle strength, anterior stability, and clinical results regardless of the amount of preserved tissue length at short-term assessment.
