Cryotherapy significantly reduces postoperative pain following anterior cruciate ligament (ACL) reconstruction surgery. While it did not improve range of motion or drainage, its effectiveness in pain management makes it a valuable addition to knee surgery recovery.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Rehabilitation

Background:

  • Cryotherapy is a common post-operative treatment after orthopedic procedures.
  • Previous studies on cryotherapy after anterior cruciate ligament (ACL) reconstruction were often underpowered.
  • A need exists to consolidate evidence on cryotherapy's effectiveness in ACL surgery recovery.

Purpose of the Study:

  • To conduct a meta-analysis evaluating the efficacy of cryotherapy after arthroscopically-assisted ACL reconstruction.
  • To assess the impact of cryotherapy on postoperative drainage, range of motion, and pain.
  • To determine the overall benefit of cryotherapy in the context of ACL surgery.

Main Methods:

  • Systematic search of electronic databases and reference lists for relevant randomized clinical trials.

  • Inclusion of studies comparing cryotherapy to a placebo group post-ACL reconstruction.
  • Application of random-effects models to synthesize data from seven included randomized controlled trials.

    • Main Results:

    • Cryotherapy did not significantly affect postoperative drainage (P=.23) or range of motion (P=.25).
    • A statistically significant reduction in postoperative pain was observed with cryotherapy (P=.02).
    • Seven randomized controlled trials were included in this meta-analysis.

    Conclusions:

    • Cryotherapy demonstrates a significant benefit in controlling postoperative pain after ACL reconstruction.
    • No significant improvements were noted for postoperative range of motion or drainage.
    • Given its cost-effectiveness, ease of use, patient satisfaction, and safety profile, cryotherapy is recommended for post-knee surgery management.
