Abstract
Purpose: To compare the rates of revision anterior cruciate ligament (ACL) reconstruction, meniscal reoperation, and total knee arthroplasty associated with partial meniscectomy and meniscal repair performed at the time of index ACL reconstruction in patients with concurrent meniscus and ACL tears.
Methods: The TriNetX database was queried for patients undergoing ACL reconstruction after January 1, 2000, with minimum 1-year clinical follow up. Inclusion criteria for this study were patients who had partial meniscectomy, meniscal repair, or isolated ACL reconstruction without meniscus injury. Statistical analyses were performed using Python with significance thresholds of P < .05.
Results: A total of 39,126 patients were followed for an average of 5.02 years. Patients undergoing meniscal repair were less likely to experience revision ACL reconstruction compared with those undergoing partial meniscectomy (relative risk [RR] 0.78, confidence interval [CI] 0.71-0.85, P < .001). Meniscus reoperation occurred significantly more in patients undergoing meniscal repair (RR 1.26, CI 1.17-1.35, P < .001) than those undergoing partial meniscectomy. Regarding total knee arthroplasty, partial meniscectomy carried a more than 6-fold increased risk compared with isolated ACL reconstruction (RR 6.4, CI 2.49-16.42, P < .001).
Conclusions: In patients with ACL injury, ACL reconstruction, and concurrent meniscus tear, those patients treated with meniscus repair were less likely to undergo revision surgery. In these patients, medial meniscal injuries were associated with ACL revision than lateral meniscal injury regardless of the method of treatment. When meniscus repair is performed, this is associated with lower rate of future total knee arthroplasty.
Level of evidence: Level III, retrospective cohort study.
期刊介绍：
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
