The Functional Assessment (FA) test offers a quick, objective measure of function after knee replacement surgery. This simple timed test effectively quantifies patient improvement, proving more useful than questionnaires.

Area of Science:

Orthopedics
Physical Therapy
Rehabilitation Medicine

Background:

Questionnaires provide limited objective data for assessing functional recovery post-knee arthroplasty.
Accurate functional measurement is crucial for evaluating treatment outcomes in knee replacement patients.

Purpose of the Study:

To evaluate the utility of the Functional Assessment (FA) test for quantifying patient function before and after knee arthroplasty.
To determine if the FA test is a practical and objective tool for clinical use in this population.

Main Methods:

The study included 445 individuals: 313 controls and 132 patients with advanced knee arthritis undergoing arthroplasty.
The Functional Assessment (FA) test, a timed measure of standing, walking, and stair navigation, was administered.

Arthroplasty patients were assessed pre- and post-operatively using the FA test.

Main Results:

The FA test demonstrated longer completion times in individuals with knee arthritis compared to controls.
A significant improvement in FA test times was observed in patients following knee arthroplasty.
The FA test requires less than one minute to administer, highlighting its clinical practicality.

Conclusions:

The Functional Assessment (FA) test is a valuable, objective tool for measuring function in knee arthroplasty patients.
Its ease of administration and short duration make it suitable for routine clinical assessment.
The FA test provides a simple yet effective method for quantifying functional changes before and after knee surgery.
