This review aimed to evaluate the certainty of evidence for the use of cryotherapy in patients with musculoskeletal disorders. PubMed, Embase, Cochrane Library and AMED were searched from January 2000 to January 2018 (update June 2019) for systematic reviews (SRs) and randomized controlled trials (RCTs) reporting outcomes on pain, swelling, range of motion (ROM), function, blood loss, analgesic use, patient satisfaction and adverse advents. The papers were categorised into: surgical procedures, acute pain or injury and long-term pain or dysfunction. Methodological quality and risk of bias were assessed using the AMSTAR and the Swedish Health Technology Assessment instruments. Level of certainty of evidence was synthesized using GRADE. Eight SRs and 50 RCTs from a total of 6027 (+839) were included. In total 34 studies evaluated cryotherapy in surgical procedures, twelve evaluated cryotherapy use in acute pain or injury and twelve studies evaluated cryotherapy in long-term pain and dysfunction. The certainty of evidence is moderate (GRADE III) after surgical procedures to reduce pain, improve ROM, for patient satisfaction and few adverse events are reported. Cryotherapy in acute pain and injury or long-term pain and dysfunction show positive effects but have a higher number of outcomes with low certainty of evidence (GRADE II). Cryotherapy may safely be used in musculoskeletal injuries and dysfunctions. It is well tolerated by patients. More advanced forms of cryotherapy may accentuate the effect. Future research is needed where timing, temperature for cooling, dose (time) and frequency are evaluated.
