“…The robot-assisted system is a new technology which uses computed tomography (CT) data of patients’ lower limb to make a preoperative plan and three -dimensional planning to orientate and size and uses the robotic arm to cut the bone and place for components [ 23 , 24 ]. Several robotic-assisted TKA systems, including CASPAR, Tsolution, ROSA, ROBODOC and Mako, have been implemented into clinical application [ [25] , [26] , [27] , [28] ]. Previous studies showed that robotic-assisted TKA can offer more accurate bone cuts, precise placement of implants and provide balanced extension and flexion gaps [ 29 , 30 ].…”

“…Pre-test scores ranged from 44.00-76.00 for PGY3, 68.00-83. 20 score after rotation. We believe instituting pre-and post-testing for the sport medicine rotation has provided the residents and fellows an objective way to measure their knowledge, improvement, and satisfaction during the rotation.…”

Background:The competency in orthopaedic surgery and sports medicine has been reported as a deficiency. Sports medicine clinical rotations may improve both medical students' and residents' musculoskeletal knowledge, but none have evaluated the knowledge and skills a resident may gain during the rotation in sports medicine.Objective: The purpose of this study is to determine (1) The knowledge gained by residents at varying levels after rotating within our sports medicine program and (2) The performance of residents in a standardized sports medicine test at the start and end of each resident's rotation in sports medicine. Methods: Total of 136 residents and fellows participated in this study following the Model Curriculum and Guidelines for Orthopaedic Surgery Sports Medicine Fellowship Training created by the American Orthopaedic Society for Sports Medicine Accreditation Council of Graduate Medical Education. Multiple modalities training program were administered, including clinical rotation, laboratory research project, covering professional sport team training, and conference presentation. Their performances were assessed and compared by pre-and post-rotation tests with statistical analysis to determine the improvement of their orthopaedic knowledge. Results:The residents at the fifth of Post-Graduate-Year (PGY 5) scored the highest followed by fellows. PGY5 had the lowest percent change between pre-and post-test. PGY 2 and PGY3 residents scored the lowest overall while having the largest percent change before and after the rotation thereby showing the most improvement.Conclusions: Multiple modalities training program improved residents and fellows' performance and knowledge in sports medicine.

“…Several studies have reported that a 1° increase in PTS after TKA improved the postoperative maximum flexion angle by 1.7°. 32 Schafer et al 33 demonstrated the use of MAKOplasty software to determine several anatomic measurements. In their study, they found a mean medial tibial slope to be 10.0° ± 6.3° and a lateral tibial slope to be 10.2° ± 3.96°.…”

“…With further analysis, they found African American patients to have greater medial and lateral tibial slopes than Caucasian patients (10.767 ± 4.493 vs 7.884 ± 3.652 and 10.887 ± 4.475 vs 9.917 ± 3.633, respectively). 33 Farooq et al 9 demonstrated the importance of maintaining a PTS close to the native tibial slope. They found that if native tibial slope was changed by more than 5° or if the femoral component was placed in extension or flexion > 10° patients were more likely to be dissatisfied with their total knee arthroplasties.…”

Arthrofibrosis in Robotic Total Knee Arthroplasty: An Investigation Into How Robotic Assistance May Contribute to a Tight Knee

Introduction: Arthrofibrosis after total knee arthroplasty (TKA) can lead to pain and restricted range of motion. Matching native knee kinematics is crucial in avoiding arthrofibrosis postoperatively. However, manual jig-based instruments have demonstrated variability and inaccuracy during primary TKA. Robotic-arm-assisted surgery was developed to increase the precision and accuracy of bone cuts and component alignment. In the literature, limited information on arthrofibrosis after robotic-assisted TKA (RATKA) exists. The purpose of this study was to compare the incidence of arthrofibrosis after manual TKA (mTKA) with RATKA by examining the need for manipulation under anesthesia (MUA) postoperatively and evaluating preoperative and postoperative radiographic parameters. Methods: A retrospective analysis of patients who underwent primary TKA from 2019 to 2021 was conducted. Rates of MUA were evaluated and perioperative radiographs were analyzed to determine posterior condylar offset ratio, Insall-Salvati Index, and posterior tibial slope (PTS) in patients who underwent mTKA versus RATKA. Range of motion was recorded for patients who required MUA. Results: A total of 1234 patients were included, of which 644 underwent mTKA, and 590 underwent RATKA. Thirty-seven RATKA patients compared with 12 mTKA patients required MUA postoperatively ( P < 0.0001). A significant decrease in PTS postoperatively was seen in the RATKA (7.10° ± 2.4° preoperatively versus 2.46° ± 1.2° postoperatively), with a mean decrease of the tibial slope of −4.6° ± 2.5° ( P < 0.0001). In patients requiring MUA, a larger decrease was seen in the RATKA group when compared with the mTKA group (mean −5.5 ± 2.0 versus −5.3 ± 0.78, P = 0.6585). No significant difference was seen in the posterior condylar offset ratio and Insall-Salvati Index in both groups. Discussion: When conducting RATKA, it is important to match PTS close to the native tibial slope to decrease the incidence of arthrofibrosis postoperatively, as a decrease in PTS can lead to decreased postoperative knee flexion and poor functional outcomes.
