The impact of insurance status on patient placement into inpatient and outpatient orthopaedic surgical centers.

BACKGROUND: Innovation has fueled the shift from inpatient to outpatient care for orthopaedic joint arthroplasty. Given this transformation, it becomes imperative to understand what factors help assign care-settings to specific patients for the same procedure. While the comorbidities suffered by patients are important considerations, recent research may point to a more complex determination. Differences in reimbursement structures and patient characteristics across various insurance statuses could potentially influence these decisions. METHODS: Retrospective binary logistic and ordinary least square (OLS) regression analyses were employed on de-identified inpatient and outpatient orthopaedic arthroplasty data from Albany Medical Center from 2018 to 2022. Data elements included surgical setting (inpatient vs. outpatient), covariates (age, sex, race, obesity, smoking status), Elixhauser comorbidity indices, and insurance status. RESULTS: Patients insured by Medicare were significantly more likely to be placed in inpatient care-settings for total hip, knee, and ankle arthroplasty when compared to their privately insured counterparts even after Centers for Medicare and Medicaid Services (CMS) removed each individual surgery from its inpatient-only-list (1.65 (p < 0.05), 1.27 (p < 0.05), and 12.93 (p < 0.05) times more likely respectively). When compared to patients insured by the other payers, Medicare patients did not have the most comorbidities (p < 0.05). CONCLUSIONS: Medicare patients were more likely to be placed in inpatient care-settings for hip, knee, and ankle arthroplasty. However, Medicaid patients were shown to have the most comorbidities. It is of value to note Medicare patients billed for outpatient services experience higher coinsurance rates. LEVEL OF EVIDENCE: III.

Successful Return to Sport and Daily Activities After Suture Augmentation of Both the Anterior Talofibular Ligament and Calcaneofibular Ligament.

Purpose: To evaluate the return to sport and daily activities in addition to clinical outcomes after modification of the Brostöm repair, specifically using suture augmentation for concomitant fixation of both the anterior talofibular ligament and calcaneofibular ligament. Methods: Patients who had grade III ankle sprains and lateral ankle instability, all of whom failed supervised conservative management, were included. Patients underwent a modified Broström procedure consisting of suture augmentation for both the anterior talofibular ligament and calcaneofibular ligament. For clinical outcome evaluation, Foot and Ankle Ability Measure (FAAM) and Karlsson-Peterson Scoring System for Ankle Function questionnaires coupled with questions regarding time of return to sport and level of sports activity were used. Results: Thirty-one patients were included. The differences in preoperative and postoperative FAAM scores for both the Activities of Daily Living subscale and Sports subscale were significant (P < .001). The FAAM Activities of Daily Living score improved from an average of 46.06 preoperatively to 77.49 postoperatively (P < .001, 99% confidence interval, 26.4-36.4). The FAAM Sports score improved from an average of 4 preoperatively to 19.31 postoperatively (P < .001, 99% confidence interval, 11.6-19.0). For the Karlsson-Peterson Scoring System for Ankle Function, the surveyed population reported a mean of 82.74 points out of 100 post-op (standard deviation 20.14). The mean time to return to sport activity was 5.72 months. Mean follow-up time was 24.12 months. Conclusions: This variant Broström procedure with suture anchors and augmentation of both the anterior talofibular ligament and calcaneofibular ligament was effective in helping patients return to their preinjury functionality level in both daily life and sports activity. Level of Clinical Evidence: Level IV, therapeutic case series.

Isolated Anterior Talofibular Ligament (ATFL) vs Combined ATFL and Calcaneofibular Ligament Suture Tape Augmentation for the Treatment of Lateral Ankle Instability: Are Outcomes Equivalent?

Background: The Broström procedure with suture tape augmentation has become commonplace for surgical treatment of chronic lateral ankle instability. However, there is no consensus among surgeons whether internal bracing of the ATFL alone or a combined ATFL and calcaneofibular ligament (CFL) internal brace produces superior clinical outcomes. This retrospective study aims to investigate whether isolated internal bracing of the ATFL has comparable outcomes to combined ATFL and CFL brace. Methods: There were 85 patients from a single tertiary medical center's electronic medical record identified who underwent an ATFL or ATFL and CFL reconstruction between January 2017 and December 2020. Postoperative outcomes including patient satisfaction, ankle instability, ankle pain, and the need for revision surgery at 1-year follow-up were evaluated. Results: Forty-eight patients underwent isolated ATFL reconstruction, and 37 underwent combined ATFL and CFL reconstruction. The choice was made between the 2 options based on surgeon preference. At 1-year follow-up, postoperative outcomes were statistically indistinguishable between the 2 treatment groups. Conclusion: The modified Broström reconstruction with ATFL and CFL reconstruction with an internal brace did not produce superior functional outcomes measured at 1 year compared to isolated ATFL reconstruction. Further investigation of long-term functional outcomes is needed to evaluate the long-term efficacy of combined or single-ligament reconstruction.Level of Evidence: Level III, retrospective study.
