Abstract

Total knee replacement is an effective treatment for knee arthritis. While the majority of Total Knee Arthroplasties (TKAs) have proved promising long-term results, however, up to 25% of patients remain dissatisfied with the outcome of surgery at 1 year. A lack of connection between surgeons and patients in evaluating the outcome of (TKA) has led to the development of a Patient-Reported Outcome Measures (PROM) to evaluate these procedures. Implant malalignment has been involved as a contributing factor to less successful outcomes. In this review we tried to explain the evolution of the PROM concept and its different types and explaining the relationship between limb and component malalignment and PROM.
