Immediate Post-Operative Phase (1-4 Days):
Precautions:- DO NOT remove steri-strips.
- Change surgical dressing 2-3 days postoperatively and replace with 4x4 gauze if drainage is present. (If you are a patient of Dr. Zahn, wait until your first physical therapy session for the therapist to change the dressing for you).
- Perform sponge baths or shower with saran wrap covering surgical site. (If you are a patient of Dr. Zahn, sponge baths only. No showers until follow up with him at 1 week after surgery)
- Avoid resisted knee extension to protect graft.
- If you experience malaise, fever, or chills- contact your physician immediately.
- Perform home exercise program issued at pre-op from Hamilton Orthopedics Physical Therapy Department.
- Control acute inflammation with the use of Cryocuff, 15-20 minutes hourly, rest, elevation, and prescribed medications.
- Ambulation: weight bearing as tolerated with the use of bilateral crutches or walker, a postoperative brace on involved lower extremity.
- Primary goal is to achieve terminal knee extension and good quad control.
Acute Phase (5 days - 2 weeks):
- Begin Physical Therapy 5 days postoperatively for 3 sessions per week.
- Continue to ambulate with post-op brace, needs to be worn for all weight bearing activity for 6 weeks.
- Continue to avoid resisted knee extension.
- Steri –strips should remain intact for approximately 2 weeks post–op.
- Ambulation/Gait training: begin with stance shifts to regain good quad control and advance to single crutch, then no assistive device by 2 weeks.
- Patella mobilization.
- Ankle pumps.
- Isometric quad sets.
- Active and passive terminal knee extension.
- Straight leg raises, adding resistance as tolerated ( hip flexion, abduction).
- Flexibility of hamstring, gastroc-soleus, quadriceps, hip adductors.
- AAROM: wall-slides, heel-slides, and knee flexion in chair.
- Standing calf lifts.
- Partial wall squats(<45 degrees of flexion).
- Closed chain resisted terminal knee extension (i.e ball squeeze at wall).
- Active Knee extension 90-40 degrees.
Acute Phase Continued (14 days - 4 weeks):
- Continue to progress above exercises.
- Range of motion: 0-120 degrees.
- Continue patella mobilization as needed.
- Proprioceptive and single leg balance activities (if able to fully weight bear through involved lower extremity).
- Stationary lunge.
- Partial wall squats (<60 degrees of flexion).
- Stationary bike (when able to achieve 110 degrees of flexion).
- Leg press (0-90 degrees).
- Sub maximal quad and hamstring isometrics at 45 degrees of knee flexion.
- Stairmaster, Nordic Track.
- Forward/ lateral step-ups (4-8 inches).
- Continue to control edema and discomfort.
Subacute Phase (4-7 weeks):
- Continue to progress above exercises.
- At 4 weeks begin active range of motion knee flexion and hip extension.
- Begin resisted knee extension from 90-40 degrees.
- Begin squats (machine based only, NO free weight squats x 6 mos.).
- Begin eccentric quad strengthening.
- Range of motion: 0-135 degrees/full.
- Emphasize closed kinetic chain therapeutic exercise.
- Walking lunges at 6 weeks post op.
- At 6 weeks post-operatively begin resisted knee flexion and hip extension.
- Aerobic stepping (Reebok step program) forward and lateral at 6 weeks post op.
- Fitting for sports specific functional ACL brace at Hamilton Orthopaedics at 6 weeks. Discontinue postoperative brace at that time.
Return to Activity Phase (8-11 weeks):
- Continue to progress above exercises with emphasis on single leg strengthening for all resistive strengthening.
- Perform 8 week functional test with forms provided by Hamilton Orthopaedics. Fax results to Surgeon, (315) 824-8961.
- If patient successfully completes the test, they may begin interval jogging, uniplanar double leg plyometrics, double-leg agility work, and dynamic flexibility programming.
- All plyometrics, jogging, and agility should be performed with the functional ACL brace on.
Activities Progression Phase (12-15 weeks):
- Continue to progress above exercises.
- Perform 12 week functional test with forms provided by Hamilton Orthopaedics. Fax results to Surgeon, (315) 824-8961.
- If patient successfully completes the test, they may begin single leg uniplanar and double leg multiplanar plyometrics, and progress ladder work accordingly.
- Continue jogging program, progressing to tolerance.
- Begin sport specific training as indicated.
- All plyometrics, jogging, and sports specific training should be performed with the ACL brace on.
Return to Prior Level of Recreational Activities (16-20 weeks):
- Continue to progress resistive and endurance exercises.
- Perform 16 week functional test with forms provided by Hamilton Orthopaedics. Fax results to Surgeon, (315) 824-8961.
- Prior to discharge, perform sports related drills implementing directional changes and sprinting.
- Return to sports when released by physician.
