Item Effects of Urinary Tract Infection on Hip and Knee Arthroplasty Outcomes(2021) Garcia, Laura; Barnes, Kalan; Dalton, Stewart; Teigen, Kari; Wagner, RussellIntroduction: Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common procedures performed in the United States. However, the effects of periprosthetic joint infections (PJI) can be devastating leading to invasive interventions and potentially impaired functionality, decreased patient satisfaction, and increased mortality. Risk factors for the development of PJIs have been well-documented, however, the association between urinary tract infections (UTIs) and PJIs remains controversial. Our aim was to establish the risk of developing a PJI in patients with an identified UTI in the preoperative, perioperative, and postoperative periods. Methods: Through retrospective chart review, data was abstracted from electronic medical records from JPS Health Network of all patients with a scheduled THA and TKA since 2014. We identified patients with UTIs 15 days prior to surgery and followed up with 12 months post-surgery for subsequent development of PJI. Results: A total of 2,220 surgeries were scheduled, and 1,697 surgeries were completed. Forty-six patients with a UTI completed surgery within 15 days of the UTI diagnosis, and 2 patients developed a PJI (4.3%, 95% Confidence limits: 0.5%, 14.8%) within 12 months post-surgery. Out of 1,274 patients with a surgery without UTI, 47 (3.7%, 95% confidence limit: 2.7%, 4.9%) developed a PJI. Conclusions: Our data does not suggest UTI in the preoperative period increases the risk of PJIs after THA and TKA. However, the study needs more power to establish significant results. Future analysis will look at the association between UTIs in the postoperative setting and PJI development.Item Extensor Tendon Repair Outcomes Based on Timing of Repair(2021) Garcia, Laura; Yousuf, Hayyan; Pientka II, William; Dalton, StewartPurpose:Extensor tendons lie superficially on the dorsum of the hand, and are covered by relatively thin soft tissue. As such, they are prone to injury and are associated with morbidity. Mechanism of injury can vary from simple lacerations to more complex injuries with severe tissue damage. Appropriate acute management of flexor tendon injuries has been shown to be associated with more favorable outcomes; however, the extensor tendon has only recently begun to receive the same attention. There is a known correlation between surgical outcomes of flexor tendon lacerations and time from injury to repair, but the same data does not exist for extensor tendon injuries. In the present study, we aim to determine if a correlation exists between the time from injury to tendon repair, and post-surgical joint stiffness as a predictor of surgical outcomes. Methods: We have conducted a retrospective chart review of patients who have undergone extensor tendon repair surgery at JPS Health Network since 2012. Results: Our preliminary data analysis reveals that among patients that experienced surgical stiffness, there was a statistically significant relationship between increased time to surgery and increased occurence of post surgical stiffness. Conclusion: Our preliminary data indicates that early repair of extensor tendon repair should be considered in order to avoid post operative joint stiffness.
