Determining the reversibility of joint contractures in
an animal model can have clinical relevance for patient
care and for resource utilization. If contractures are largely
reversible, treatment is not justified. If largely irreversible,
delays in diagnosis or treatment may be costly since currently,
there is no effective medical treatment to reverse
or cure long-lasting joint contractures. For these reasons,
a comprehensive reversibility experiment using a rat model
and including quantitative measures of ROM over a
time course would provide the rationale to improve the
management of joint contractures.
In the current study, knee joint flexion contractures of
various severities underwent incremental durations of
spontaneous recovery in a rat model. The range of knee
extension was measured using an automated goniometer.
Our objectives were 1) to determine whether knee
joint contractures are fully reversible during recovery
without treatment and 2) to determine the duration of
spontaneous recovery that produces maximal partial reversibility
of joint contractures. Our hypotheses were
that 1) while early-onset knee flexion contractures may
be reversible, long-lasting contractures do not fully reverse
spontaneously and 2) while initial partial reversibility
may occur, extending the duration of recovery does
not lead to further gains in knee extension.
This study provides evidence-based guidelines on the
timing of intervention to manage joint contractures of
various severities by accurately predicting their natural
course.
