LCS mobile bearing total knee arthroplasty without patellar resurfacing. Does the unresurfaced patella affect outcome? Survivorship at a minimum 10-year follow-up. | LitMetric
Background: Patellar resurfacing during total knee arthroplasty (TKA) remains controversial. The aim of this study was to evaluate the long-term outcomes of a mobile-bearing TKA without patellar resurfacing.
Methods: We assessed the outcomes in 503 patients (600 knees) who had cemented LCS (low contact stress) mobile bearing TKA without patellar resurfacing at a minimum follow-up of 10 years. Clinical outcome scores and radiological assessment were used.
Results: Four knees were revised, two had bearing dislocation and nine patients (1.5%) had secondary resurfacing for anterior knee pain. There were no radiolucent lines or osteolytic defects on radiographic evaluation. The overall survivorship was 97.8% with re-operation for any reason as the endpoint.
Conclusion: Non-resurfacing of the patella does not adversely affect the outcome of the LCS mobile bearing TKA at minimum 10 years follow-up.
Background: Total ankle arthroplasty (TAA) has been developed as treatment for disabling tibiotalar osteoarthritis. TAAs are divided into mobile- and fixed-bearings. The aim was to determine the incidence and trends of fixed- and mobile bearings over time and investigate the association of bearing type and risk of revision after primary TAA in the Netherlands.

Background: Total knee arthroplasty (TKA) mainly involves the femoral, tibial, and bearing implants. Bearings are categorized by posterior cruciate ligament (PCL) status (cruciate-retaining [CR] vs. posterior-stabilized [PS]) and motion (mobile vs.
Background: The presence of full-thickness cartilage in the lateral compartment on valgus stress radiography is a criterion for medial mobile-bearing unicompartmental knee arthroplasty (UKA). However, the appropriateness of medial UKA is uncertain when preoperative MRI shows extrusion of the lateral meniscus. We therefore assessed how preoperative MRI-detected lateral meniscus extrusion affects mid-term functional outcomes after mobile-bearing UKA.
Introduction: Hypovitaminosis D plays an important role in post-operative bone pain and muscle strength in arthroplasty surgeries. Its role in unicompartmental knee arthroplasty (UKA) has not been elucidated yet. The objective of this study was to determine the impact of hypovitaminosis D and its correction on post-operative bone pain after UKA.
The interest in performing total ankle arthroplasty (TAA) to address end-stage ankle osteoarthritis (OA) is continuously growing. Sports activity plays an important role in our world. The literature is sparse regarding return-to-sports activity following TAA.
