OBJECTIVE: To identify predictors of poor exercise adherence in patients with
osteoarthritis (OA) and meniscal tear. DESIGN: Secondary analysis of data
gathered over the first 12 weeks in the Meniscal Tear in Osteoarthritis Research
(MeTeOR) trial, a multicenter, randomized controlled trial. SETTING: Seven
referral centers. PARTICIPANTS: Most of the patients in the MeTeOR trial (N=325
of 351) were included in the analysis, each of whom was aged >/=45 years and had
a meniscal tear and osteoarthritic changes on imaging studies; 26 were excluded
because of missing data from which to derive the primary outcome variable.
INTERVENTIONS: All patients received a structured, supervised exercise program
focused on strengthening, along with prescribed home exercises; half were
randomly assigned to also receive arthroscopic partial meniscectomy. MAIN OUTCOME
MEASURE: Poor exercise adherence through 12 weeks, defined as performing <50% of
prescribed exercise. RESULTS: Thirty-eight percent of the MeTeOR cohort showed
poor exercise adherence. In the multivariate model, adjusting for treatment
group, those who earned </=$29,000 per year had 1.64 times the risk of
nonadherence (95% confidence interval [CI], 1.10-2.43) than those who earned
>$100,000 per year; and those without baseline pain with pivoting and twisting
had 1.60 times greater risk of nonadherence than those with these symptoms (95%
CI, 1.14-2.25). CONCLUSIONS: Low income was associated with poor exercise
adherence among patients aged >/=45 years with OA and a meniscal tear, as was
absence of pain with pivoting and twisting. Our findings highlight the need for
further research into exercise adherence and for interventions to enhance
adherence among those with low incomes.
