Isolated patellar resurfacing served as an early treatment for patellofemoral arthritis but was abandoned because of erosion of the native femoral trochlear groove over time. We present the case of a large native tibial osteolytic lesion 20 years after isolated patellar resurfacing with a cemented polyethylene component. The patient had severe tricompartmental arthritic changes. The patellar component was very worn, and the resultant particle debris produced a large cavitary lesion in the proximal tibia. Osteolysis is a rare complication in patellofemoral arthroplasty, and, to our knowledge, this is the first reported case of native tibial osteolysis after isolated patellar resurfacing. The patient was treated with initial curettage and bone grafting of the lesion followed by total knee arthroplasty with a tibial cone and stemmed tibial fixation.

Introduction: Total knee replacements are becoming more prevalent. There is still a lot of controversy regarding patellar resurfacing. Surgeons advocating for resurfacing state reduced risk for anterior knee pain and need for future revision surgery.

Aim The primary objective of the study was to evaluate the mid-term implant survivability, rate of revisions, and clinical and functional outcomes following patella resurfacing during total knee arthroplasty (TKA) utilizing posterior stabilized (PS) total knee system (TKS). Methods A prospective, single-arm, multi-center, post-marketing surveillance encompassed patients with end-stage primary knee osteoarthritis (OA) or inflammatory arthritis. The time points of the study included baseline, six weeks, six months, one year, and three years post-operatively.

Introduction: Micromotion analysis predicts component fixation survival in Total Knee Arthroplasty (TKA) but a paucity of literature exists for medial pivot designs. This clinical study examined the tibial component micromotion in a second-generation medial pivot TKA.
Methods: This prospective single-center clinical cohort trial involved 35 patients with a mean patient age of 71 years.

Objective: To compare the mid- and long-term effectiveness of patellar resurfacing versus non-resurfacing in primary total knee arthroplasty (TKA).
Methods: Twenty-six patients who underwent bilateral TKA between March 2013 and September 2015 were selected as the study subjects. One side was randomly chosen for patellar resurfacing (resurfacing group), and the other side was not (control group).
Introduction: Undertaking a primary total knee arthroplasty for chronic complete patellectomy knees is an infrequent and complex scenario. The technical demands are high, often leading to suboptimal outcomes. However, our innovative approach, which involves a patellar autograft from an intraoperatively cut femoral condyle placed into the extensor mechanism following cement resurfacing, has shown promising results.
