The management of the patella during total knee arthroplasty (TKA) has been a matter of considerable debate in the orthopaedic community. 1 – 4 Surgeons tend to approach the patella with one of three general mindsets: always resurface the patella

loosening than the first-generation MoM-THR and thus became the preferred bearing over MoM. 1 - 4 Around the turn of the millennium, a second generation of MoM-THR, including resurfacings, was introduced with the claim of reduced wear and superior

Introduction Large-head metal-on-metal (MoM) bearings were re-popularised in the late 1990s with the introduction of modern hip resurfacing (HR), followed shortly afterward by large metal head total hip arthroplasty (THA). The introduction of

patients with more advanced arthritis, operative management has centred on arthrodesis of the first MTP joint. Multiple joint-sparing procedures such as joint arthroplasty or resurfacing have been described with inconsistent results. Pathophysiology

Introduction The Kinematic Alignment (KA) technique for total knee arthroplasty (TKA) is an alternative surgical technique aiming to resurface knee articular surfaces. 1 , 2 Ultimately, the goal of KA is to alter the knee physiological

simplistic terms, the KA technique is almost a true resurfacing of the TFJL, where implant thickness aims to replace the exact same amount of ‘bone cartilage’ removed and therefore to restore the highly variable individual native pre-arthritic (or

Vitallium prosthesis secured with a single transfixing screw to resurface the patella alone, as described by McKeever in 1955, 17 reportedly showing good functional results, and offering an alternative to patellectomy in isolated patellofemoral
