Treatment of Knee Sprain

Initial Management

  • The British Journal of Sports Medicine and American Family Physician recommend functional treatment with early exercise therapy and functional support for knee sprain treatment, leading to faster recovery and return to normal activities 1, 2
  • Functional treatment should be initiated as soon as possible after injury, consisting of three phases: protection, exercise therapy, and endurance training, as recommended by the American Family Physician 2
  • NSAIDs may be used to reduce pain and swelling in the acute phase, according to the British Journal of Sports Medicine and American Family Physician 1, 2
  • The traditional RICE protocol is no longer recommended as a standalone treatment, as there is no evidence that it positively influences pain, swelling, or patient function, as stated by the British Journal of Sports Medicine 4, 1

Evidence on Individual Components

Functional Support

  • The British Journal of Sports Medicine recommends a brace as the preferred functional support option for knee sprains, providing better outcomes than immobilization 1, 2
  • Functional support should be used for 4-6 weeks to promote healing while maintaining joint mobility, as recommended by the British Journal of Sports Medicine 1
  • Lace-up or semirigid supports are more effective than tape or elastic bandages for supporting injured joints, according to the American Family Physician 2

Exercise Therapy

  • The British Journal of Sports Medicine recommends starting exercise therapy as soon as possible to recover joint functionality 1
  • Supervised exercises focusing on proprioception, strength, coordination, and function are recommended for optimal recovery, as stated by the British Journal of Sports Medicine 1
  • Exercise therapy has been shown to be effective for preventing recurrent sprains and should be incorporated into regular training activities, according to the British Journal of Sports Medicine 1

Pain Management

  • NSAIDs have been shown to reduce pain in the short term without significantly increasing adverse events, as recommended by the British Journal of Sports Medicine 4
  • Paracetamol appears to be equally effective as NSAIDs for pain management with potentially fewer side effects, according to the British Journal of Sports Medicine 4
  • NSAIDs may potentially delay natural healing as they suppress inflammation, which is a necessary component of tissue recovery, as stated by the British Journal of Sports Medicine 4

Cryotherapy (Ice)

  • Cryotherapy alone has limited evidence supporting its effectiveness, as stated by the British Journal of Sports Medicine and American Family Physician 4, 2
  • If used, cryotherapy appears most beneficial when combined with exercise therapy rather than as a standalone treatment, according to the British Journal of Sports Medicine 4

Return to Activity

  • Functional treatment allows patients to return to sports approximately 4.6 days sooner than immobilization, as recommended by the American Family Physician 2
  • Patients using functional treatment return to work approximately 7.1 days sooner than those treated with immobilization, according to the American Family Physician 2
  • A functional approach with early weight-bearing leads to the fastest resumption of work and daily activities, as stated by the British Journal of Sports Medicine and British Journal of Sports Medicine 3, 5

Common Pitfalls to Avoid

  • Complete immobilization of the knee should be avoided as it shows no benefits and delays recovery, as recommended by the British Journal of Sports Medicine and American Family Physician 1, 2
  • The RICE protocol should not be relied upon solely as there is insufficient evidence for its effectiveness as a standalone treatment, according to the British Journal of Sports Medicine and British Journal of Sports Medicine 4, 1
  • Heat application should be avoided in the acute phase of injury, as stated by the American Family Physician 2
  • Delaying the initiation of exercise therapy should be avoided, as early movement promotes better healing and functional outcomes, as recommended by the British Journal of Sports Medicine 1
