In vivo cartilage strain differentiates symptomatic, asymptomatic, and healthy knees six months after ACL reconstruction

Key Points

• Symptomatic knees demonstrated significant cartilage strain compared to healthy and asymptomatic knees six months post ACL reconstruction.
• The key metric of cartilage strain was analyzed across three groups: symptomatic, asymptomatic, and healthy knees over six months.
• Assessment using in vivo cartilage strain measurements distinguishes knee health status following ACL reconstruction surgery.
• Findings suggest that monitoring cartilage strain could inform rehabilitation strategies, but external validation is required.
