Summary: This study compared the early postoperative clinical outcomes and component alignment between the minimally invasive small incision (MISI) technique and conventional minimally invasive surgical (MIS) techniques in unicompartmental knee arthroplasty (UKA). The results showed that the MISI group had faster recovery, shorter hospital stays, and smaller incisions, but longer tourniquet usage time. There were no significant differences in range of motion, pain scores, and knee society scores between the two groups at six months postoperative follow-up, as well as no statistical differences in radiographic measurements.

Summary: Unicompartmental knee replacement (UKR) has gained popularity in young athletes with high demands. This study aimed to show the rate of return to activity and sporting activity of patients aged 60 years or younger following lateral UKR with a fixed-bearing prosthesis.

Summary: The aim of this research is to develop a low-cost autonomous system for robotic-assisted knee arthroplasty, with a novel image-free registration process to eliminate the need for radioactive scans. The system was tested on artificial tibia bones and compared to the Mako and BlueBelt systems, showing smaller mean and maximum errors.

Summary: This study aimed to assess the return to sport rate in patients who underwent CT-based robotic-assisted unicompartmental knee arthroplasty (RA-UKA) and evaluate the clinical performance and association between patients' sport activity levels and Patient Reported Outcome Measures after surgery. The study found that patients who participated in sports had higher activity levels and satisfaction after surgery.

Summary: This study evaluated the mid-term survivorship and patient-reported outcomes of robotic-assisted lateral unicompartmental knee arthroplasty (UKA). The results demonstrated high survivorship and excellent patient satisfaction with robotic-assisted lateral UKA, even in patients who did not meet classic indications.

Summary: This study evaluates the clinical outcomes and survivorship of robotic-arm assisted unicompartmental knee arthroplasty (RA-UKA) for the lateral compartment. The results demonstrate significantly improved outcomes, high patient satisfaction, and excellent functional recovery at midterm follow-up. Comparative studies are needed to further assess the differences between robotic-assisted and conventional lateral UKA.

Summary: This study aimed to determine the learning curve of a UKA robotic-arm assisted system. The results showed learning curves in operative time, femoral rotation, and insert sizing, indicating the need for careful operation during the learning phase. However, there was no impact on patient outcomes and implant survival, suggesting that robotic-arm assisted UKA may be particularly useful for low-usage surgeons.

Summary: The study found an association between radiographic Ahlback osteoarthritis grade and postoperative joint perception, with patients with higher OA grade more likely to attain a forgotten knee after medial robotic arm-assisted unicompartmental knee arthroplasty. Patients with less severe OA were less likely to achieve the Patient Acceptable Symptom State. However, predicting outcomes for cases with poorer results remains difficult.

Summary: The study found that robotic-assisted UKA has a lower revision rate compared to conventional UKA in short-term follow-up. There was no difference in the general complications rate between both groups. No specific complications due to the robotic-assisted system were observed.

Summary: This study investigated the feasibility of using pinless navigation for tibial component implantation in unicompartmental knee arthroplasty. The results showed that the pinless navigation technique and the conventional technique achieved similar results in positioning the tibial component, with negligible differences in surgical time.

Summary: Robotic assisted unicompartmental knee arthroplasty (RAUKA) is a successful approach that improves implant positioning accuracy, minimizes soft tissue injury, and enhances patient outcomes. This review provides an overview of the historical development, features of the robotic arm and navigation systems, and characteristics of contemporary RAUKA. It also compares conventional unicompartmental arthroplasty with RAUKA and discusses current challenges and future advancements in the field.

Summary: This study assessed the cost-effectiveness of robotic-arm assisted total knee arthroplasty (TKA) compared to conventional TKA in the Medicare-aged population. It found that despite higher robotic purchase costs, robotic-arm assisted TKA is likely to be cost-effective relative to TKA in high-volume hospitals, due to lower revision rates and decreased post-acute care costs.

Summary: This study assessed the clinical outcome and mid-term survivorship of mobile-bearing unicompartmental knee arthroplasty in patients 50 years of age or younger. The results showed significant improvements in knee function and pain in the short term, but further long-term follow-up is needed to evaluate the efficacy.

Summary: The study investigated the association between intraoperative component positioning and soft tissue balancing in robotic arm-assisted lateral UKA surgeries, finding that three-dimensional component positioning did not affect short-term clinical performance. Robotic assistance provides real-time information on implant alignment and soft tissue balancing.
