Purpose: To compare knee osteoarthritis (OA) incidence within 5 years of surgery between 5 common sports medicine procedures: isolated anterior cruciate ligament (ACL) reconstruction, isolated meniscus repair (MR), isolated arthroscopic partial meniscectomy (APM), ACL reconstruction with MR (ACL + MR), and ACL reconstruction with APM (ACL + APM).
Methods: The PearlDiver Mariner M157Ortho database was searched. Five cohorts were identified using () codes and included those 16 to 60 years old who underwent isolated ACL reconstruction, isolated MR, ACL + MR, isolated APM, or ACL + APM repair. Groups were matched by age, sex, and presence of diagnosis codes for obesity. The incidence of knee OA diagnosis within 5 years of the index procedure was determined for each group, and odds ratios (ORs) were calculated and compared against isolated ACL reconstruction.
Results: Each group consisted of 7,672 patients (3,450 females, 4,222 males). A significantly greater proportion of the APM group was diagnosed with knee OA within 5 years of surgery compared to isolated ACL reconstruction (APM = 1,032/7,672 [13.5%] vs ACL = 745/7,672 [9.7%]; ≤ .001; OR, 1.45; 95% confidence interval [CI], 1.31-1.60). Similarly, a greater proportion of the MR group was diagnosed with OA compared to isolated ACL reconstruction (MR = 826/7,672 [10.7%]; = .030; OR, 1.12; 95% CI, 1.01-1.25). No differences in OA incidence were noted between the ACL + APM group when compared to isolated ACL reconstruction ( = .81). Patients undergoing ACL + MR demonstrated the lowest OA incidence with reduced odds when compared to isolated ACL reconstruction (ACL + MR = 575/7,672 [7.5%]; < .001; OR, 0.75; 95% CI, 0.67-0.84).
Conclusions: In this analysis using codes, APM was associated with the highest knee OA incidence, and ACL + MR was associated with the lowest OA incidence within 5 years of surgery.
Level Of Evidence: Level III, retrospective cohort study.
