Summary: This study conducted a cost-effectiveness analysis of total hip and knee arthroplasties in the New Zealand healthcare system, finding that THA and TKA are highly cost-effective procedures over a 15-year period. They were cost-effective after 2 years and highly cost-effective after 3 years. Patients with worse preoperative functional status and younger age showed greater quality-adjusted life year gains and cost-effectiveness.

Summary: This scoping review explores the optimal combination of motor-sparing analgesic interventions for TKR patients. Femoral triangle blocks combined with periarticular infiltration provide better pain control, higher patient satisfaction, and reduced opioid consumption. Future trials are needed to investigate the additional benefits of other analgesic modalities such as IPACK, popliteal plexus block, and genicular nerve block.

Summary: Unicompartmental knee arthroplasty (UKA) for isolated medial or lateral osteoarthritis yields good clinical outcomes, but has higher revision rates compared to total knee arthroplasty (TKA). In this retrospective study, 537 patient-specific UKAs implanted over 10 years were analyzed for survival and fitting. The study found excellent midterm survival rates, especially in the lateral knee compartment, and confirmed excellent fitting with less than 1 mm tibial overhang in 99% of cases.

Summary: In total knee arthroplasty for obese patients, patient-specific instrumentation (PSI) was found to be more costly and less effective compared to standard of care (SOC) from a healthcare payer perspective. However, from a societal perspective, PSI had an incremental cost-utility ratio of $11,230.00 per quality-adjusted life year gained, which was considered cost-effective.

Summary: This study compared the costs and operative times of using CT-based, patient-specific, single-use instruments versus conventional metal instruments for TKA. The results showed that patient-specific, single-use instruments reduced the number of instrumentation trays by more than one-third and saved 36% in sterilisation costs.

Summary: This study examined the prevalence of treatments and their financial impact in patients with stiffness after primary TKA. It was found that patients with stiffness after TKA require more treatments and follow-up visits, and the treatment costs are higher compared to patients without stiffness.

Summary: This study evaluates the cost-effectiveness of malnutrition screening and intervention for TKA patients through a Markov model from a societal perspective. The findings suggest that universal screening and intervention are cost-effective in reducing the risk of periprosthetic joint infection (PJI).

Summary: This study compares the radiological accuracy and clinical outcomes between patient-specific instrumentation (PSI) and traditional cutting block techniques in total knee arthroplasty. The results show no significant difference in alignment angles or functional outcomes between the two groups at a minimum of 5-year follow-up.

Summary: The decision to resurface the patella during total knee arthroplasty may be influenced by various factors, but ultimately both resurfacing and non-resurfacing have similar patient-reported outcomes. Resurfacing the patella is cost-effective and associated with a lower rate of re-operation compared to non-resurfacing.

Summary: The study compared the efficacy and accuracy of robotic-arm system, patient-specific instrumentation (PSI), and conventional total knee arthroplasty (TKA). Results showed that robotic-arm-assisted TKA had the least intraoperative bleeding but the longest operation time. In terms of postoperative radiographic results, both the robotic-arm system and PSI group had better angles compared to the conventional group. However, there were no significant differences in functional scores among the three groups. Therefore, the robotic-arm system offers a more minimally invasive and accurate approach to TKA.

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: Assessing the effectiveness of PSI-aided TKA involves analyzing component alignment, patient-reported outcome measures (PROMs), surgery time, blood loss, transfusion rate, and postoperative complications. While PSI may not benefit expert surgeons, it could improve accuracy and patient safety during the learning curve of novice surgeons.

Summary: This study investigated the role of body mass index (BMI) in the cause for revision total knee arthroplasty (TKA) and whether BMI classification is predictive of outcomes. The study found significant differences in primary and repeat revision etiologies among weight classes, with obese and morbidly obese patients having a greater risk of requiring repeat revision surgery.

Summary: This study introduced a patient-specific integrated education program (IEP) for total knee arthroplasty (TKA) patients and compared outcomes with a control group. The IEP group showed significant reductions in pain intensity during hospitalization and before discharge, improvements in anxiety scores, and enhanced functional recovery compared to the control group. The results suggest that the patient-specific IEP is effective in reducing postoperative pain, decreasing perioperative anxiety, and facilitating functional recovery following TKA.

Summary: This study found that patients undergoing outpatient TKA had higher implant and overall hospital costs compared to UKA patients, with increased postoperative personnel costs leading to a higher overall facility cost.
