Purpose Part-two of this consensus aimed to provide recommendations for the prevention of meniscus injuries, non-operative treatment of acute tears and degenerative lesions, return to sports, and patient-reported outcome measures. Methods This consensus followed the European Society of Knee Surgery, Sports Traumatology and Arthroscopy (ESSKA) formal consensus methodology. For this combined ESSKA- American Orthopedic Society for Sports Medicine (AOSSM) - American Academy of Sports Physical Therapy (AASPT) initiative, 67 experts from 14 countries, including orthopedic surgeons and physiotherapists, were involved. The 26 Steering Group members established guiding questions, screened the existing evidence, and proposed statements, and provided Grades of recommendations. The 41 Rating Group members assessed the statements according to a Likert scale (1-9). Final documents were assessed by an international peer review group for geographical adaptability. Results Low to moderate scientific level of evidence was available, so that grades of recommendations were low (three Grade A ratings, four Grade B, three Grade C and 13 Grade D), underlining the relevance of this consensus. One strong and 17 relative agreements with overall median of 8 (8-9) and a mean of 7.92 +/- 0.37 were achieved for 23 statements on 18 questions. Prevention of meniscus injuries is possible with general knee injury reduction programs and through avoidance of certain activities. Non-Operative treatment including physical therapy is the first line approach for degenerative meniscus lesions and may be an option for some acute tears. Return to sports after meniscus tear surgery should be both criterion-based and time-based. Patient reported outcomes in combination with performance-based measures are recommended to evaluate the rehabilitation process. Conclusion This international EU-US consensus established recommendations for prevention strategies, describes rehabilitation of non-operated patients and of patients after partial meniscectomy, meniscus repair and meniscus reconstruction, and establishes return to sport criteria. These updated and structured recommendations may be applied by surgeons and physiotherapists. Level of Evidence I, Formal Consensus.

Abstract Purpose The aim of part one of this EU‐US consensus was to combine literature research and expertise to provide recommendations for the usage of rehabilitation (including physical therapy) of patients undergoing surgical treatment for degenerative meniscus lesions or acute meniscus tears (including meniscectomy, repair, or reconstruction). Prevention programmes, non‐operative treatment of acute tears and degenerative lesions, return to sports and patient‐reported outcome measures will be presented in a part II article. Methods This consensus followed the European Society for Sports Traumatology and Arthroscopy (ESSKA)'s ‘formal consensus’ methodology. For this combined ESSKA, American Orthopedic Society for Sports Medicine and American Academy of Sports Physical Therapy initiative, 67 experts (26 in the steering group and 41 in the rating group) from 14 countries (US and 13 European countries), including orthopaedic surgeons, sports medicine doctors and physiotherapists were involved. Steering group members established guiding questions, searched the literature and proposed statements. Rating group members assessed the statements according to a Likert scale and provided grades of recommendations, reaching a final agreement about rehabilitation of the knee after meniscus surgery. Final documents were then assessed by a peer review group to address the geographical adaptability. Results The overall level of evidence in the literature was low. Of the 19 questions (leading to 29 statements), 1 received a Grade A of recommendation, 2 a Grade B, 9 a Grade C and 17 a Grade D. Nevertheless, the mean median rating of all questions was 8.2/9 (9 being the highest rating on a scale of 1–9). The global mean rating was 8.4 ± 0.2, indicating a high agreement. Rehabilitation depends on the type of lesion, the treatment performed and is the same after medial or lateral meniscus surgery. Rehabilitation after meniscectomy should follow a criterion‐based rehabilitation protocol, based on milestones rather than a time‐based protocol. After meniscus repair and reconstruction, rehabilitation should be progressed according to both time and criterion‐based milestones. Conclusion Rehabilitation after meniscus surgery is a debated topic that may influence surgical outcomes if not optimally performed. This international formal consensus established clear, updated and structured recommendations for both surgeons and physiotherapists treating patients after meniscus surgery. Level of Evidence Level I, consensus.

Background Knee injuries are prevalent in cutting, pivoting, and jumping sports. Studies have investigated the effects of exercise-based knee injury prevention programs, however no clinical practice guidelines (CPG) exist. Objective 1) Review the evidence for exercise-based knee injury prevention programs, 2) identify if there are exercise-based knee injury prevention programs that are effective for particular groups of athletes, 3) explore the evidence for dosage and delivery of exercise-based knee injury prevention programs, 4) provide information on how exercise-based knee injury prevention should be implemented. Design Systematic review for CPG development. Setting Multiple. Patients (or Participants) Healthy, active individuals, particularly athletes participating in cutting, pivoting, and jumping sports. Interventions (or Assessment of Risk Factors) A systematic review of literature was performed via PubMed, Scopus, SportDiscus, CINAHL, and the Cochrane databases for relevant articles addressing the effects of an exercise-based knee injury prevention program. The final search was performed in April, 2016 to identify all articles published prior to that point. Main Outcome Measurements The effects and outcomes of exercise-based knee injury prevention programs. Results Thirty-seven studies met the inclusion criteria for this CPG. Exercise-based knee injury prevention programs have a low implementation cost and large relative risk reductions. Clinicians should implement an exercise-based knee injury prevention program for all athletes involved in cutting and pivoting type sports to reduce the number of significant knee injuries. The program should be implemented two to three times per week in the preseason and one to three times per week in the competitive season. It should consist of a combination of plyometric training, strength and power exercises, balance and dynamic stabilization training, core strengthening, technique training, and/or sports-specific drills. Conclusions This CPG will provide evidence based guidance for clinicians in choosing and implementing exercise-based knee injury prevention programs appropriate for the athlete(s) they work with.
