Hinged cast after knee ligament surgery.

S Sandberg, B Nilsson, N Westlin

    The American Journal of Sports Medicine
    |May 1, 1987
    PubMed
    Summary

    A hinged cast significantly reduced sick leave for anterior cruciate ligament (ACL) injuries and improved range of motion for all knee ligament injuries post-surgery. Early motion in hinged casts did not compromise knee stability.

    Area of Science:

    • Orthopedic surgery
    • Sports medicine
    • Rehabilitation

    Background:

    • Knee ligament injuries often require surgical repair.
    • Postoperative immobilization is crucial for healing.
    • Traditional long leg casts can prolong recovery and limit early motion.

    Purpose of the Study:

    • To compare the efficacy of hinged casts versus long leg casts for postoperative immobilization after knee ligament repair.
    • To evaluate the impact on recovery time, range of motion, and knee stability.

    Main Methods:

    • Randomized controlled trial involving 113 patients undergoing knee ligament repair.
    • Patients were immobilized in either a hinged cast or a long leg cast post-surgery.
    • Outcomes measured included time of disability (sick leave), range of motion, and knee stability.

    Main Results:

    • Hinged casts significantly shortened sick leave duration (6 weeks) specifically for anterior cruciate ligament (ACL) injuries.
    • Patients in hinged casts demonstrated more rapid regain of range of motion across all injury types.
    • No adverse effects on knee stability were observed with the use of hinged casts.

    Conclusions:

    • Hinged casts offer a potential advantage in accelerating recovery and improving range of motion after knee ligament surgery.
    • Early mobilization within a hinged cast appears safe and does not negatively impact knee joint stability.
    • This suggests hinged casts may be a beneficial alternative for postoperative management of knee ligament injuries.
