Abstract
Background: The thrust plate prosthesis (TPP) is an alternative to a stemmed total hip prosthesis. This stemless femoral implant designed for total hip arthroplasty (THA) was developed to simulate the physiological loading of the metaphysis of the proximal femur and can be used in young patients. Methods and findings: This retrospective study describes the mid-term results of a cohort of 171 patients (in total 200 procedures) who received a TPP for the indication of primary osteoarthritis of the hip. These mid-term results are defined by the complication free survival, which includes dislocation, periprosthetic fracture, infection, thromboembolism, pneumonia, and cardiologic complications. Conclusions: Of the 200 procedures the complication free survival rate was 94% and the revision free survival rate was 97.5% with a mean follow-up of 9.03 years.
