Abstract Background Multiligament knee injuries, though rare, can be profoundly disabling. Surgeons disagree about when to initiate rehabilitation after surgical reconstruction due the conflicting priorities of postoperative stability and motion. Questions/purposes (1) Does early or late initiation physical therapy multiligament surgery result in fewer manipulations? (2) versus compromise postoperatively? (3) improved patient-reported outcomes, as measured by Multi-ligament Quality Life...
