Publication High satisfaction and functional improvement following robotic‐assisted total knee arthroplasty: A Latin American cohort study(2025) Calvo, Rafael; Figueroa, David; Landea, Daniela; Gonzalez, Waldo; Isla, Jorge; Figueroa, LoretoPurpose: Total knee arthroplasty (TKA) is a widely performed surgical procedure for patients with severe knee osteoarthritis, aiming to reduce pain, improve function, and enhance quality of life. Patient satisfaction following TKA typically ranges from 85% to 90%, with factors such as malalignment and postoperative instability being common causes of dissatisfaction. Robotic-assisted TKA (RA-TKA) has demonstrated advantages in surgical precision and better functional recovery compared to conventional techniques. The objective of our study is to evaluate and quantify the level of patient satisfaction and functional outcomes after robotic-assisted TKA. Methods: Prospective cohort of patients who underwent TKA using robotic-assisted surgery at a single centre between 2018 and 2020. Demographic data were collected, and patient satisfaction was evaluated at the 1-year follow-up using the Knee Society Scoring (KSS) system. Functionality was assessed through patient-reported outcome measures (PROMs), specifically the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR), both preoperatively and postoperatively, with a minimum follow-up period of 3 years. All statistical analyses were performed using STATA version 18.5. Results: A total of 270 patients with complete follow-up were evaluated. 92.6% (n = 250) of patients were satisfied or very satisfied with the surgery, while 7.4% (n = 20) reported dissatisfaction. No statistically significant difference was found in age, sex, BMI, or preoperative Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) between the satisfaction and dissatisfaction groups. However, satisfied patients had a significantly higher postoperative KOOS JR (p = 0.0001). Conclusion: A high level of satisfaction and significant functional improvements were achieved after robotic-assisted TKA in patients with severe osteoarthritis.Publication Return-to-sport tests: Do they reduce risk of re-rupture after anterior cruciate ligament reconstruction?(2026) Figueroa, David; Gonzalez, Waldo; Landea, Daniela; Tapia, Camila; Erskine, DanielaIntroduction: Anterior cruciate ligament (ACL) rupture is one of the most common knee injuries. Despite the effectiveness of reconstruction, re-rupture rates of up to 15 % have been reported. Static and dynamic test of strength and movement control have been used to determine when return to sports (RTS) is appropriate. Objective: To determine whether successfully passing return to sport (RTS) tests reduces the re-rupture rate. Methods: Retrospective cohort study. Patients who underwent ACL reconstruction (ACLR) from June 2018 to May 2023, and who performed RTS tests after rehabilitation, were analyzed. Patients who, in addition to ACLR, underwent extra-articular tenodesis, osteotomy, or multiligament injuries were excluded. RTS tests included the following: repeat sprint ability, dynamic valgus, proagility, unilateral counter movement jump (CMJ), isokinetic, triple hop test, and functional movement screen (FMS). All statistical analyses were performed with STATA version 18.0. Results: Ninety five patients underwent RTS tests after ACLR, with a follow-up time of 27.8 months. 71.6 % of patients were men with a mean age of 25.15 ± 10.7 years. The overall re-rupture rate was 13.68 % (13 patients). When comparing patients who passed and did not pass the RTS tests, there were no differences by sex (p = 0.06) or age (p = 0.11). The only statistically significant difference between the groups was the mean risk score (passed: 11.5 ± 0.7 vs. not passed: 15.5 ± 2.1; p < 0.001). Patients with re-rupture were more likely to be from the non-passed group (passed: 0 % v/s not passed: 18.1 %; p = 0.03), with a statistical power of 0.70. Conclusion: Our records show that passing RTS test after an ACLR could guarantee the absence of re-rupture in the medium term
