Why supervised exercise therapy works
A 2026 La Trobe University trial published in the Annals of Internal Medicine studied 184 adults (ages 18-40) who still had knee problems one to three years after ACL reconstruction. Those who completed a four-month, physiotherapist-led progressive exercise program reported less knee pain, better function, and stronger thigh muscles than those who received a single education session and exercised on their own — and MRI showed no deterioration of knee cartilage. Supervised guidance made the difference.
