Song M, Sun X, Tian X, Zhang X, Shi T, Sun R, Dai W. Compressive cryotherapy versus cryotherapy alone in patients undergoing knee surgery: a meta-analysis. Springerplus. 2016 Jul 13;5(1):1074.
Design: Meta-analysis of randomised controlled trials.
Methods: 10 RCTs were selected, including 522 patients who underwent knee surgery. Outcomes included: Pain intensity (visual analog scale), Swelling (knee circumference measured using tape), Adverse events (thermal injury such as frostbite and transient nerve palsy).
Results:
Key message: Cold + Compression is more beneficial for reduction of pain and swelling at the early postoperative period for knee surgery than cold alone.
• Patients who underwent compressive cryotherapy tended to have less pain than patients who underwent cryotherapy alone at postoperative day (POD) 2 and POD3 • Compressive cryotherapy had a strong tendency towards less swelling over cryotherapy alone at POD1 and POD2. • However, there was no significant difference between compressive cryotherapy and cryotherapy alone at the intermediate stage of rehabilitation after knee surgery.
