Unicompartmental knee arthroplasty (UKA) has seen a revival of popularity in the last thirty years in the United States. The benefits of a medial UKA over the previous 'gold standard' for knee osteoarthritis, the total knee arthroplasty, include increased postoperative range of motion (ROM), maintenance of natural knee mechanics, faster recovery, similar pain relief and decreased morbidity. Mobile-bearing UKA (MB-UKA) implants have been developed to improve polyethylene wear while maintaining normal knee kinematics. In this review, we will cover indications and contraindications for aN MB-UKA, patient selection, and technical tips and tricks.

Background: Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain. Pain control is crucial for rapid mobilisation and reduces side effects as well as the length of hospital stay. In this context, a variety of multimodal pain control regimes show good pain relief, including several nerve blocks, iPACK and local infiltration analgesia (LIA).

Purpose Of Review: Artificial intelligence (AI) offers a new frontier for aiding in the management of both acute and chronic pain, which may potentially transform opioid prescribing practices and addiction prevention strategies. In this review paper, not only do we discuss some of the current literature around predicting various opioid-related outcomes, but we also briefly point out the next steps to improve trustworthiness of these AI models prior to real-time use in clinical workflow.
Recent Findings: Machine learning-based predictive models for identifying risk for persistent postoperative opioid use have been reported for spine surgery, knee arthroplasty, hip arthroplasty, arthroscopic joint surgery, outpatient surgery, and mixed surgical populations.

Purpose: This study was conducted to determine the effect of early mobilization on pain and mobility levels in individuals undergoing total knee arthroplasty.
Design: Randomized controlled clinical trial.
Methods: This study was carried out in the orthopedic and traumatology department of a public hospital in Turkey.

Objective: Robotic-assisted total knee arthroplasty (TKA) is a novel orthopedic technique. The workflow of robotic-assisted TKA is quite different from that of traditional manual TKA and may result incompletely different resection parameters. Understanding these parameters may help surgeons better perform robotic-assisted TKA.

Background: There is no consensus on whether adductor canal block (ACB) combined with infiltration between the popliteal artery and capsule of the posterior knee (IPACK) block can further increase analgesia and reduce opioid consumption after total knee arthroplasty (TKA) compared with ACB and periarticular infiltration analgesia (PIA).
Purpose: This study aimed to evaluate the effectiveness of combining ACB and PACK block on analgesia and functional recovery following TKA.
Methods: A retrospective cohort study was conducted involving 386 patients who underwent primary unilateral TKA at our institution from January 2020 to October 2022.
