Postoperative Rehabilitation Protocol for ACL Reconstruction
- Program is designed to protect the ACL and the patella, and get full extension early
- Even with addition of meniscus repair no significant changes made in rehab
- Patellofemoral protection is important; no wall slides or lunges, only do mini squats
- Assume twelve weeks graft to bone healing time
- With hamstrings or Allograft flexion is restricted to 90 degrees for first 4 weeks to reduce stress on graft
- ACL with posterolateral corner or LCL repair follows different post-op care, i.e. crutches x eight weeks and brace to avoid varus stress
General Progression of Activities for Daily Living
Patients may begin the following activities at the dates indicated (unless otherwise specified by the physician):
- Showering – once dressing removed; no immersion until stitches/staples removed and wounds healed, if brace is present may remove for shower.
- If patient has a brace may sleep without brace after comfortable (usually a few days) unless there is cartilage repair or lateral side surgery then same for WB restrictions.
- Driving: when safely able to operate the controls of the vehicle. Any time for left knee surgery (assuming automatic transmission), and longer for right leg surgery.
- Full weight bearing without crutches usually by two weeks or as tolerated, however for meniscus repair toe touch for about four weeks, and eight weeks when any lateral side surgery also performed.
Physical Therapy Attendance
The following is an approximate schedule for supervised physical therapy visits:
- Formal PT begins after 1st post-op visit usually about two weeks
- 3 times per week is optimal
- Home exercises daily as instructed by the therapist
- Supervised physical therapy takes place for approximately three-to-five (3-5) months post-op
Begins immediately following surgery and lasts approximately one month. Patient is to perform ROM exercises and hip, knee and ankle strengthening as directed daily.
- Protect healing bony and soft tissue structures
- Minimize quadriceps atrophy and joint stiffness through:
- Early range of motion with emphasis on full extension, patella mobilizations and flexion limit dependent on graft choice, meniscus repair and other concurrent surgery (i.e., lateral side)
- PRE’s for quadriceps, hip and calf
- Patient education for a clear understanding of limitations and expectations of the rehabilitation process
Weight Bearing Status (unless with meniscal repair*)
- 0-1 weeks: Partial weight bearing with two crutches to assist with
- 1-2 weeks: Partial weight bearing with normal gait mechanics
- After two weeks, full weight bearing allowed based on quad function
* With meniscal repair weight bearing may be kept toe-touch for one- month post-op, lateral side surgery six-to-eight (6-8) weeks.
From zero to two weeks:
- Straight leg raises and quad sets for quads tone
- Ankle Pumps
- Patella mobilizations
- Passive full extension
- Active flexion to 90 if possible
Add at the first post-op visit two weeks out through week four:
- Standing toe raises for calf muscle tone
- For bone-tendon-bone may begin AAROM for full ROM, begin exercise
bike, mini-squats, balance training
- For hamstrings or Allograft same exercises as above but limit flexion to
90 (i.e., mini-squats, balance, bike is OK)
- After sutures out at two weeks if pool available may begin aquatics (walk
in pool, mini-squats). Pool is helpful but not essential..
Begins at one month post-op, and extends to the twelfth post-op week.
- Increase range of motion for all patients/all grafts progress to full flexion
- Progress in weight bearing for all patients/all grafts according to previous precautions (i.e., lateral side surgery six-to-eight (6-8) weeks of crutch/brace)
- Continue lower extremity muscle toning
- Begin functional restoration of leg function for balance and ADL
- Begin total patient reconditioning with non-impact cardiovascular
- Continue to protect graft(s)
From four to twelve weeks: Once patient is full weight bearing and does not require the brace, therapy can be liberalized and proceed on a more “as tolerated” basis.
- Begin isometric quads and co-contraction of quads/hams
- Progress to mini-squats when able to be full weight bearing, graduated step
- May continue hip flexion/extension/Abduction/Adduction
- Closed kinetic chain for knee extension utilizing resisted band while standing
and weight machines as follows. Leg press is OK, active open chain knee
flexion is OK.
- Stationary bike, XC ski machine, Stairmaster and/or elliptical machines can be
used for cardio and leg conditioning
- Balance and Proprioception activities (e.g. single leg stance or mini-
Begins approximately three months post-op, and extends to four to five months post-op. Expectations for advancement to Phase III:
- Restore any residual loss of motion that may prevent functional progression
- Improve functional strength and proprioception utilizing closed and/or open
kinetic chain exercises
- Continue to work on restoration of functional progression of the extremity
and the patient as a whole in preparation for return to activity or sports
- Continue lower extremity exercise progression with emphasis on quads tone and strength
- Treadmill walking progress to running as tolerated
- Stairmaster/elliptical trainer, swimming is OK (no breast stroke)
- May progress to out door biking, walking and ultimately running
- May play golf or bowling if able
- No twisting turning or jumping activities yet
Return to sport approximately five to six months.
- Safe and gradual return to work or athletic participation
- This may involve sports specific training, work hardening or job restrictions as needed
- Maintenance of strength, endurance and function
- Running progression
- Figure 8 progression, Carioca, Backward running, cutting
- Jumping (plyometrics) if needed for sport (i.e., volleyball or basketball)
* These instructions are to be used as general guidelines. Before three months it is important not to go any faster even if the patient seems able, since the most important consideration is graft protection. Please have physician contacted if there are questions or concerns.
