Overview of the Progression of Knee Range of Motion (ROM) Status, Knee Bracing, and Exercise Rehabilitation Undertaken by Both the Accelerated and Traditional Rehabilitation Groups

Postoperative Timeline	Rehabilitation Overview
Week 1	Knee ROM: passive and active ROM from 0°-30° Knee bracing: 0°-30° Treatment/rehabilitation: isometric contractions and circulation exercises, CPM (0°-30°) and cryotherapy
Weeks 2-3	Knee ROM: active ROM from 0°-30° (week 2) to 0°-60° (week 3) Knee bracing: 0°-30° (week 1-2) to 0°-60° (week 3) Treatment/rehabilitation: isometric and straight leg exercises, passive and active knee flexion exercises, remedial massage, soft tissue and patella mobilization, CPM (0°-90°), cryotherapy, and hydrotherapy
Weeks 4-6	Knee ROM: active ROM from 0°-90° (week 4) to 0°-130° (week 6) Knee bracing: 0°-90° (week 4) to full range (week 5) Treatment/rehabilitation: introduction of calf raises, weighted hip adduction and abduction, trunk strengthening, recumbent cycling
Weeks 7-12	Knee ROM: active ROM from 0°-130° (week 6) to full range (week 7) Knee bracing: full knee flexion (brace worn until 12 weeks postsurgery) Treatment/rehabilitation: introduction of proprioceptive/balance activities, cycling, walking, resistance, and CKC activities

Note: ROM = range of motion; BW = body weight; CPM = continuous passive motion; CKC = closed kinetic chain; OKC = open kinetic chain.
