5 Reasons Why Your Flexion Sucks After ACL Surgery

In this concise monologue, Victoria S. Dorsano highlights a common but under‑discussed problem after anterior cruciate ligament (ACL) reconstruction: loss of knee flexion. She explains that while many resources focus on regaining extension, flexion deficits often stem from five key issues. First, the inevitable swelling that follows the surgical trauma makes bending the knee difficult. Second, swelling can re‑accumulate if the patient over‑uses the joint or progresses too quickly in rehab. Third, poorly managed postoperative pain discourages patients from performing the necessary range‑of‑motion exercises. Fourth, limited patellar mobility—where the kneecap does not track smoothly—can mechanically block flexion. Fifth, arthrofibrosis, a pathological scar tissue formation, can severely restrict motion if it develops. Dorsano notes that her full YouTube video expands on each cause and offers specific strategies to restore flexion.
