Continuous passive motion as an adjunct therapy for tenolysis.

J A McCarthy, P A Lesker, W W Peterson

    Journal of Hand Surgery (Edinburgh, Scotland)
    |February 1, 1986
    PubMed
    Summary

    Continuous passive motion after tenolysis increases tendon rupture and decreases range of motion due to scar tissue formation. This study evaluated its efficacy as an adjunct therapy.

    Area of Science:

    • Orthopedic Surgery
    • Rehabilitation Medicine
    • Biomedical Engineering

    Background:

    • Tenolysis is a surgical procedure to free adhered tendons.
    • Continuous passive motion (CPM) is sometimes used post-surgery to improve outcomes.
    • The efficacy of CPM as an adjunct to tenolysis requires further investigation.

    Purpose of the Study:

    • To evaluate the use of continuous passive motion (CPM) as an adjunct therapy following tenolysis.
    • To assess the impact of CPM on tendon integrity and joint mobility post-tenolysis.

    Main Methods:

    • A model was developed to evaluate CPM's effects.
    • The study compared outcomes between a CPM group and a control group (implied).
    • Measurements included tendon rupture incidence, active flexion force, and passive range of motion.

    Main Results:

    • CPM use was associated with a significant increase in tendon rupture.
    • A higher terminal force was required for active phalanx flexion in the CPM group.
    • A decrease in passive range of motion was observed in the CPM group, attributed to increased granulation tissue formation around the tenolysed tendon.

    Conclusions:

    • Continuous passive motion as an adjunct to tenolysis may negatively impact tendon healing and joint mobility.
    • Increased granulation tissue formation is a potential complication of CPM after tenolysis.
    • Further research is needed to determine optimal post-tenolysis rehabilitation protocols.
