What is the standard postoperative protocol after Lisfranc injury?

• A. Non-weight-bearing for 6-8 weeks, then 2-4 weeks partial weight bearing in CAM boot
• B. Non-weight-bearing for 2 weeks, then full weight bearing
• C. Partial weight bearing immediately in CAM boot for 6 weeks
• D. Cast immobilization for 12 weeks

Answer: (A)

Protection and gradual loading are the guiding principles after a Lisfranc injury repair. The standard approach starts with non-weight bearing for about 6 to 8 weeks to shield the repair and allow the ligaments and any fixation to heal in proper alignment. Once that initial healing window passes, weight bearing is gradually introduced in a controlled way, typically transitioning to partial weight bearing in a CAM boot for about 2 to 4 weeks, before progressing to full weight bearing as tolerated and with radiographic confirmation of stability. This sequence minimizes the risk of displacement, hardware failure, and posttraumatic arthritis while promoting joint and soft-tissue healing. Shorter non-weight bearing, immediate partial or full weight bearing, or prolonged cast immobilization for 12 weeks are not considered standard because they either increase the risk of displacement or stiffness without offering the best balance of protection and rehab.
