PCL Reconstruction
Phase I – Maximum Protection (Weeks 0 to 6):
Weeks 0 to 6:
- Brace at all times locked at 0°/0° for six to eight weeks
- Ice and modalities to reduce pain and inflammation
- Use crutches PWB for 6 weeks
Range of Motion
- Begin aggressive patella mobility
- Limit ROM 0°-90° with passive prone flexion or seated with anterior tibial translation by the patient or therapist for first 6 weeks
Exercises
- Quadriceps setting; towel placed behind tibia. Focusing on VMO contraction
- Blood Flow Restriction Therapy for muscle mass and quad activation
- Straight leg raises in the brace
Phase II – Progressive Stretching and Early Strengthening (Weeks 6 to 12):
Weeks 6 to 12:
- Continue with modalities to control inflammation
- Open brace 0°-90° if patient demonstrates good quadriceps function
Range of Motion
- Progress to full knee ROM. Minimize posterior tibial translation
Exercises
- May begin active hamstring contractions
- Begin total leg strengthening with SLR program (no resisted hamstrings x 12 wks)
- Bilateral closed kinetic chain squatting
- Multi-plane open and closed kinetic chain hip strengthening
- Unilateral step-up progression
- Stationary biking
- Pool program; walking and deep water exercise only. No running
- Proprioception drills
Phase III – Advanced Strengthening and Proprioception Phase (Weeks 12 to 24):
Weeks 12 to 24:
Range of Motion
- Full
Exercises
- Advance cardiovascular program; stationary bike, treadmill walking, elliptical trainer
- Increase intensity of closed kinetic chain exercises
- May begin resisted hamstring exercises
- Advance proprioception drills
- Initiate gym strengthening progressing from bilateral to unilateral as tolerated:
- Leg press, squats, partial lunges, hamstring curls, ab/adduction, calf raises
Phase IV – Advance Strengthening and Return to Sport (Weeks 20 to 9mo/12mo):
- Pool running at 20 weeks
- Dry land running at 24 weeks
- Multidirectional agility drills at 7-8 months
- Return to sport 9-12 months
