What quad strength milestone is targeted by week 6 after ACL reconstruction?

• A. 40%
• B. 60%
• C. 80%
• D. 100%

Answer: (B)

Regaining quadriceps strength is a central goal in ACL rehab, and early strength milestones guide how you progress exercises while protecting the graft. By about six weeks after ACL reconstruction, many rehab protocols target the quadriceps to reach roughly 60% of the strength of the healthy leg. This level reflects meaningful activation and control, allowing you to advance from basic range-of-motion and light resistance toward more functional exercises, while still avoiding excessive load that could jeopardize graft healing. Strength is usually measured with an objective test (often isometric knee extension) and expressed as a percentage of the uninvolved leg or the patient’s preoperative baseline. While exact targets can vary with protocol and measurement method, 60% at six weeks is a common, practical milestone that signals sufficient early recovery to progress, without pushing toward full strength or high-impact activity too soon. The other numbers represent different stages: 40% would indicate more substantial weakness and would slow progression, whereas 80% or 100% would be more typical of later phases when returning to higher-demand activities.
