OBJECTIVE: To determine whether total knee arthroplasty recipients demonstrating
comparatively poor mobility at entry to rehabilitation and who received
supervised therapy, had better rehabilitation outcomes than those who received
less supervision. DESIGN: Retrospective analysis of randomized trial data.
PATIENTS: Total knee arthroplasty participants randomized to supervised (n = 159)
or home-based therapy (n = 74). METHODS: Participants were dichotomized based on
mean target 6-min walk test (6MWT) pre-therapy (second post-surgical week).
Absolute and change in 6MWT and Western Ontario and McMaster Universities
Osteoarthritis Index (WOMAC) Pain and Function subscales amongst low performers
in the supervised (n = 89) and unsupervised (n = 36) groups were compared, as
were high performers in the supervised (n = 70) and unsupervised (n = 38) groups.
RESULTS: Low performers in the unsupervised compared with the supervised group
demonstrated significantly poorer 6MWT scores (absolute delta = 8.5%, p = 0.003;
change delta = 8.1%, p = 0.007) when therapy ceased (10 weeks post-surgery). No
differences in 6MWT were observed between the high performing subgroups or in the
recovery of WOMAC subscales between any subgroups. CONCLUSION: Individuals
manifesting comparatively poor mobility at the commencement of physiotherapy may
recover their mobility, but not perceived function, more quickly if streamed to
supervised therapy.
