Article Abstract
Robotic-assisted unicompartmental knee arthroplasty (UKA) is accurate and repeatable. Lateral UKA is still considered a challenge, as the lateral side of the knee has different anatomy and kinematics compared with the medial side. The lateral compartment of the knee is less constrained than the medial compartment and is therefore less tolerant for mobile-bearing implants and ACL deficiency. However, the long-term outcomes of lateral UKA are scarce. Moreover, the impact of patellofemoral joint degeneration on the outcome of lateral UKA is unknown. We report our preliminary results with fixed bearing robotic-assisted lateral UKA, which are encouraging in the short term.

[Relationship between knee meniscus and posterior tibial slope in healthy adults and patients with anteromedial osteoarthritis in Heilongjiang province].

The Third Orthopedic Department, the First Affiliated Hospital of Harbin Medical University, Harbin Heilongjiang, 150001, P. R. China.
Objective: To measure and analyze the relationships among the posterior tibial slope (PTS), meniscal slope (MS), and meniscus posterior horn thickness (MPHT) of the medial and lateral tibial plateau in healthy people and patients with anteromedial osteoarthritis (AMOA) in Heilongjiang province, so as to provide reference basis for appropriate tibial osteotomy and prosthesis placement angles in knee joint surgeries.
Methods: A retrospective collection of imaging data from knee joint MRI examinations conducted prior to AMOA for various reasons was performed. A total of 103 healthy individuals (healthy group) and 30 AMOA patients (AMOA group) were included.
Varus/valgus angle of the femoral component relative to the tibial component increases risk of bearing dislocation in medial mobile bearing unicompartmental knee arthroplasty.

Senior Department of Orthopedics, The Fourth Medical Center of PLA General Hospital, No. 51 Fucheng Road, Beijing, 100048, People's Republic of China.
Background: In medial mobile-bearing unicompartmental knee arthroplasty (MB-UKA), the position of the bearing does not correspond to the planned position which will increasing the risk of bearing dislocation. This study aimed to explore the relationship between the malposition of the femoral and tibial components and the phenomenon of bearing deviation using postoperative radiological measurements.
Methods: One hundred twenty patients who underwent mobile-bearing uni-compartmental knee arthroplasty (MB-UKA) at our hospital between January and August 2023 were enrolled in this retrospective study.
Relationship between the location of the popliteal artery and the tibial osteotomy plane in patients with medial and lateral unicompartmental knee arthroplasty: A retrospective analysis of preoperative magnetic resonance imaging and intraoperative findings.

Department of Orthopaedics, School of Medicine, Jichi Medical University, Shimotsuke, Japan.
Purpose: To clarify the location of the popliteal artery (PA) is relative to the tibial osteotomy plane in patients with medial and lateral unicompartmental knee osteoarthritis (KOA) undergoing UKA.
Methods: Preoperative MRI and postoperative radiographs obtained from 50 patients with unicompartmental KOA who underwent fixed-bearing UKA were analyzed. The amount of tibial resection was determined from the surgical records, and a line was drawn parallel to the tibial posterior tilt angle on the sagittal MR image to create a virtual tibial cut line.
Indications for the addition of a patellofemoral joint arthroplasty following a previous unicondylar knee arthroplasty- a literature review and Delphi consensus.

Institute for Locomotion, Aix-Marseille University, Marseille, France.
Introduction: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis.
Materials And Methods: A systematic review of the literature was conducted, and the results used to inform the development of a statement by an expert working group. This was then evaluated and modified, using a Delphi process, by members of the European Knee Society (EKS).
Intraoperatively identified patellofemoral osteoarthritis: no significant impact on short-term outcomes of medial unicompartmental knee arthroplasty.
BMC Musculoskelet Disord

Department of Orthopaedic Surgery, The First Affiliated Hospital, Fujian Medical University, No.20, Chazhong road, Fuzhou, 350005, China.
Background And Objective: The efficacy of medial unicompartmental knee arthroplasty (UKA) in patients with intraoperatively identified patellofemoral osteoarthritis (PFOA) has been a subject of debate. This retrospective study aimed to investigate the early outcomes of UKA in patients with varying intraoperative PFOA conditions and to explore the relationship between the location of PFOA and the position of the prosthesis post-UKA. Our aim was to determine whether the presence of PFOA affects the short-term success of medial UKA.
