ClinConnect Summary

Total joint replacement is an efficacious treatment for osteoarthritis of hips and knees. Both TKA and Total Hip Artrhoplasties (THA) have excellent implant survivorship. However, patients' satisfaction is lower in TKA than THA. A possible cause of the discrepancy is the unnatural knee kinematics after TKA. Various implants designs have been developed to solve the problem. The most common fixation mode is cemented TKA with good survival up to 15 years. However, newer series in younger patients also have shown lasting survival with cementless implants (Nilsson KG, Prudhon JL). Among various ...
