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).
Co-occurrence of Pigmented Villonodular Synovitis and Patellar Clunk Syndrome Following Total Knee Arthroplasty: A Case Report.

Pigmented villonodular synovitis (PVNS) is an uncommon hyperproliferative disease of the synovium presenting either as localized or a more aggressive diffuse form. Its occurrence following total knee arthroplasty (TKA) is rare, and its presentation alongside patellar clunk syndrome (PCS) has not been previously reported. We present a case of a 64-year-old female patient diagnosed with diffuse PVNS (D-PVNS) two and half years following TKA, co-occurring with PCS.

Orthopaedic surgeons hold differing opinions on replacing the patella during total knee arthroplasty (TKA) for knee osteoarthritis, sparking a continued discussion on the optimal approach. Patellar resurfacing (PR) replaces the patella's surface with a prosthetic component, aiming to enhance joint function and reduce anterior knee pain. However, it has potential complications such as avascular necrosis, fractures, and patellar clunk syndrome.

However, there remains a shortage of high-quality studies directly comparing this insert design to the established PS Total Knee Arthroplasty (TKA). This prospective randomized controlled trial (RCT) aimed to compare clinical outcomes, range of motion, and complications of UC and PS TKA.

Patellar clunk syndrome (PCS) is a complication of total knee arthroplasty (TKA) leading to audible and palpable clunking of the patellofemoral joint as the knee is extended out of deep flexion. While historically a clinical diagnosis, some cases require further workup and imaging. Here, we demonstrated the utility of dynamic ultrasound assessment for a patient with clunking after TKA and identified a variant of PCS that is not well described in the literature.
