For example, Coslick et al (Coslick et al, 2019) proposed successfully a protocol following a femur stress fracture including a loadshedding system quantifiable in percentage permitting to evolve progressively to full body-weight running. While meaningful in the context of ACL-R, the limitations inherent to the swimming pool, unloaded treadmill or load-shedding system (cost, place, maintenance, …) make it difficult to implement in clinical setting.…”
