Despite advancements in surgical techniques and rehabilitation protocols, a large portion of service members will not fully return to duty (RTD) post-ACLR and will receive a permanent profile restriction (PP) or undergo a medical evaluation board (MEB). The timing of ACLR is a modifiable factor that can potentially impact RTD and remains underexplored in this population. This study aimed to assess the relationship between the timing of ACLR and its impact on RTD and meniscal procedures performed at index ACLR.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This retrospective observational study was conducted among active duty military personnel who underwent primary ACLR at Madigan Army Medical Center between October 1, 2016, and December 31, 2022. The primary outcome was the number of RTD, PP, or MEB outcomes. Secondary outcomes included the incidence and type of meniscal procedure performed at index ACLR. Kruskal-Wallis analyses were employed to assess the relationships between time to ACLR and RTD, as well as the incidence and type of meniscal procedure performed. After separating time to ACLR into four distinct time-based groups (0-3 months, 3-6 months, 6-12 months, and &gt;12 months), a chi-squared test with post hoc analysis via Dunn's test with Bonferroni correction was conducted to identify a time interval from injury to ACLR that impacted RTD.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Initial analysis to assess the relationship between time to ACLR and outcome (RTD, PP, or MEB) were significant (P = .02). Subsequent analyses performed between 4 distinct time-based groups (0-3 months, 3-6 months, 6-12 months, and &gt;12 months) were also significant (P = .03). Pairwise comparisons revealed an 80% rate of RTD in the 0-3 month group compared to a 53% RTD rate in 3-6 month group (P = .006). However, comparisons between the 3-6 month and 6-12 month group (P = .68) and between the 6-12 month and greater than 12 month groups were not significant (P = .80).Additionally, time to ACLR significantly differed between service members who did not undergo any concurrent meniscal procedure to those who had a meniscal debridement (P = .002), and to those who underwent meniscal repair (P = .02). There was no significant difference in time to ACLR between those who underwent debridement versus repair (P = .22). Patients without any meniscal procedure had an average surgery time of 175 days, compared to 240 days for those undergoing meniscal repair and 295 days for those with meniscal debridement.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The findings from this novel study suggest that ACLR within 3 months after injury can improve the likelihood of RTD without limitations.

Managing postoperative pain after TKA is of vital importance, as it is positively associated with outcome measures related to recovery of function and quality of life. Two commonly used methods to control postoperative pain are regional anesthesia (RA), consisting of a single or a combination of peripheral nerve and epidural blocks, and pain medication, such as opioids. Our retrospective analysis sought to better understand whether revision versus primary TKA impacted previously discovered disparities in perioperative pain management and use of RA at the Atlanta Veterans Affairs Health Care System (AVAHCS). Before data collection, we hypothesized that revision TKA would have a higher proportion of Black and older patients and that revision TKA patients would have lower postoperative pain scores.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Materials and methods: &lt;/strong&gt;This was a retrospective analysis of AVAHCS patients who underwent elective unilateral primary or revision TKA surgery between 2014 and 2020.

Statistical analyses included chi-square test, t-tests, multiple logistic regression, and multiple linear regression, as appropriate to the outcomes of interest.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Revision TKA patients were more likely to be Black (P = .018) and younger (P = .023 for &lt;50 years of age group, P = .006 for 50 to 64 years of age compared to the &gt;65 years group). Black patients, compared to White patients, had significantly higher pain scores at baseline (P = .0086) and at 24 hours postsurgery (P = .0037). Older patients (≥50 years old) had significantly higher baseline pain scores (P = .021 for the 50 to 64 years group, P &lt; .01 for the &gt;65 years group) and significantly lower first postanesthesia care unit pain scores (P &lt; .05).
