Dear group: Seeking advice on protocols, thoughts for knee flexion post arthroscopic ACL repair. Different authors appear to recommend different approaches for the days 1 - 5 post op. Some suggest PROM knee flexion, others active assisted ROM, and others AROM. Understanding that initially knee flexion is not allowed with the knee in weight bearing what approaches are members of the group taking for this early stage of rehab? (Frequently the patient is not using CPM and does not present with significant edema.) Rationale and or evidence to support your approach is much appreciated. Many thanks Fran Wedge
