the principal goal of Total Knee Replacement (TKR) in the treat-

ment of knee osteoarthritis (OA) is to improve quality of life through

the restoration of joint function, and reduction of pain. In recent years,

there has been a dramatic rise in the utilisation of TKR to treat younger

patients [1], and those with higher functional expectations [2,3].

Changes in physical function following surgery have most commonly

been monitored using patient-reported outcome measures (PROMs).

Recent evidence suggests PROMs fail to capture changes in perfor-

mance-based measures following TKR surgery [4–7]. It has also been

suggested that patients with severe OA have difficulty discriminating

between functional limitation and pain when self-assessing their ability

to perform activities of daily living [4].

Gait analysis provides an objective approach for assessing the ap-

parent disparity between performance-based and perceived functional

changes pre to post TKR surgery. Numerous studies have reported

functional deficits in biomechanical parameters in TKR cohorts when

compared to healthy subjects [8]. Few studies, however, have discussed

whether patients with the greatest perceived recovery also have the

best biomechanical outcomes and vice versa.

Biomechanical gait analysis yields a wealth of information re-

garding joint kinematics and kinetics, but the interpretation of findings

is complicated by interdependencies of the biomechanical variables [9].
