Objective: We developed and validated an artificial intelligence pipeline that leverages diffusion models to enhance prognostic assessment of knee osteoarthritis (OA) by analyzing longitudinal changes in patella shape on lateral knee radiographs.
Method: In this retrospective study of 2,913 participants from the Multicenter Osteoarthritis Study, left-knee weight-bearing lateral radiographs obtained at baseline and 60 months were analyzed. Our pipeline commences with an automatic segmentation for patella shapes, followed by a diffusion model to predict patella shape trajectories over 60 months.

Introduction: To improve patient satisfaction after total knee arthroplasty (TKA), retention of the infrapatellar fat pad (IPFP) is advocated.
Source Of Data: Recently published literature identified from PubMed, EMBASE, Scopus, and Google Scholar.
Areas Of Agreement: TKA is routinely performed in patients with end-stage joint osteoarthritis, but 18% to 11% of patients are unsatisfied after surgery.

Objectives: The aim of this study was to biomechanically compare three different cementing techniques for patellar component fixation in total knee arthroplasty. MATERIALS AND METHODS: Synthetic patellar bone model (Selbones© Research Laboratory, Kayseri, Turkey) was implanted with an all-polyethylene universal dome patellar component (Trauson universal dome, Stryker, Changzhou, China) using bone cement (Surgical Simplex P, Stryker, Limerick, Ireland). The test specimens were divided into three groups according to the cementing technique.

Introduction: The optimal fixation technique for patellar components in primary total knee arthroplasty (TKA); cemented versus press-fit, remains controversial. While early press-fit designs were associated with complications, second-generation implants with improved osseointegration features have renewed interest in cementless fixation.
Methods: This systematic review included studies comparing cemented and press-fit patellar fixation in primary TKA.

Introduction: Knee osteoarthritis often starts in the patellofemoral compartment of the knee and is diagnosed in about 39% of people with knee pain aged above 30 years. Patellofemoral osteoarthritis plays a crucial role in the reduction of quality of life and in the rise of healthcare costs. There is still no consensus for treatment recommendation for isolated patella-femoral osteoarthritis in clinical guidelines.
