Revision Anterior Cruciate Ligament Reconstructions at an Urban Tertiary Referral Center in Western India: A Retrospective Cross-Sectional Study.

BACKGROUND

Anterior cruciate ligament reconstruction (ACLR) is a surgery performed to achieve knee stability and allow the knee to return to the preinjury level. There has been a significant increase in the number of primary arthroscopic ACLRs in recent years. However, the increase in primary surgeries has led to a proportional rise in revision ACLRs, primarily due to failure of the index surgery resulting from various factors.

MATERIALS AND METHODS

Hospital records from August 2020 to July 2023 were analyzed for revision ACLRs carried out at our center by a single surgeon with one year of postoperative follow-up. The patients who met the inclusion criteria and consented to participate in the study were called for clinical follow-up, and Lysholm scoring was performed to assess the functional outcome of the surgery.

RESULTS

Twenty-eight patients met the inclusion criteria, 20 of whom consented to participate in the study. The mean age of the study population was 30.5 ± 6.82 years, with 85% (n=17) being males. There was a statistically significant difference in the Lysholm scores between primary and revision surgeries, with 50% (n=10) of patients having excellent outcomes (score >90) after index surgery and only 30% (n=6) falling into that category after revision surgery. There was a significant relationship between higher Lysholm scores and return to the preinjury level of play.

CONCLUSIONS

Revision arthroscopic ACLRs have good functional outcomes in the short and medium terms and are excellent for restoring knee stability. However, the outcomes are fair compared with those of primary arthroscopic ACLRs.
