Background:

Low knee awareness after TKR has become the ultimate goal in

trying to achieve a natural feeling knee. With improving patient outcome after

TKR new assessment tools with increased discriminatory power especially in

well- performing patients are desirable. The Forgotten Joint Score (FJS) is a new

patient reported tool to determine outcomes. It evaluates to what extend the

patients are aware of the artificial knee and if the knee feels natural.

Purpose / Aim of Study:

To compare FJS with OKS in patients treated with

TKR 5 years postoperatively.

Materials and Methods:

PROM Survey. In 2015 a number of 175 consecutive

patients were enrolled in a Joint Awareness Study (100 females,75 males). All

patients received the OKS and the FJS questionnaire > 5 years postoperatively.

Responds rate 91%.

Findings / Results:

Overall satisfaction: OKS 85,5% compared to FJS 71,4%,

p<0,001. 21 patients in both OKS and FJS obtained a 100 % satisfaction, how-

ever only15 patients had the maximum score in both questionnaires. Highest

satisfaction in both score systems is achieved in personal washing/showering.

OKS 83,5%, FJS 72,5%. Lowest satisfaction was kneeling, using a dustpan OKS

18%, and rising from low position FJS 27%. FJS takes sports activity into ac-

count and regarding awareness in performing favourite sport 51% are rarely

aware of the knee.

Conclusions:

In this study a significant higher OKS compared to FJS is shown.

Questions with the highest and lowest satisfaction cover similar areas in both

questionnaires. FJS is a more sensitive tool to measure patient related outcome,

it picks up subtle differences and a less ceiling effect is shown. FJS is appealing

to measure outcome in patients with high performance.
