ACL Reconstruction Rehabilitation

While operative treatment for ACL reconstruction is important, the rehabilitation process is also vital to your health and the strength and healing time of your knee. Outlined below is a typical rehabilitation process for clients in the postoperative phase.

Preoperative Rehabilitation Phase

You have been diagnosed with an ACL tear and are anxious to “get it fixed” and return to your active lifestyle. But…it is very important for the knee to get through the acute injured state prior to having surgery. Research has clearly shown that performing an ACL surgery on a knee when it remains acutely inflamed and swollen carries a very high risk of having the postoperative complications of stiffness and pain.

Therefore, in the immediate post injury state, I recommend that you ice the knee for 20 minutes several times per day and utilize Ibuprofen 800mg three times a day or Aleve (Naproxyn) 2 pills twice per day for the first week. Additionally, you should utilize crutches as long as it is painful to bear weight.

Additionally, I will typically refer you to physical therapy to help guide through a preoperative regimen to optimize your knee’s status for surgery. Ideally, your knee will have normal range of motion, minimal swelling, and you will walk with a normal gait prior to surgery.

 

Phase 1 – Postoperative – Days 1-7

GOALS:
1. Control pain and swelling – Icing and elevation is very important in the initial post-operative phase. You will be offered a icing/compressive device (Thermacare) to use after surgery. Utilize this machine continuously for the first 3 days and then as needed. If you did not receive one of these, utilize ice packs for 20 minutes every hour.

2. ****Obtain full extension EARLY**** This is probably the most important item to work on in the first phase. I encourage you to avoid propping the leg up with a pillow behind the knee, and alternatively, prop the leg up with a support under the foot, leg and ankle which will allow the knee to extend.

3. Prevent Deep Venous Thrombosis (DVT) 

There are many things that can do to minimize your risk of developing a DVT. Utilizing an Aspirin (325 mg/day for 4 weeks) will help, and early mobilization is probably the most beneficial thing that you can do. This not only means getting up and moving, but also doing ankle/calf pumps beginning the evening of surgery.

4. CPM (Continuous Passive Motion): I recommend a CPM device for the first 2 weeks after surgery. This should be started at 0-45 degrees and increased at 5-10 degrees per day as tolerated. You should try to use this for 2 hour sessions 3 times per day.

 

Phase 2 – Return to Life – Weeks 2-8

GOALS:
1. Maintain Full Extension
2. Normalize Gait
3. Return to work/life

Gait
– As your pain and swelling diminish, I encourage you to get up and move around with crutches for support. During this first week, I want you to maintain partial weight-bearing with your brace locked in full extension. As your strength and quad control improve, your therapist will help progress you first to unlocking the brace to allow knee range of motion, and then to be off the crutches while walking.

Range of Motion

– Extension: Obtaining full extension is the primary goal of this first phase.
Avoid propping the leg with a pillow under the knee. Although this is the most comfortable position, it also makes it very difficult to maintain full extension. Alternatively, prop the leg up with support under the foot and ankle.

– Flexion: You also need to begin working on flexion. Your CPM device will help with this, but you should also work on prone flexion, heel slides and gravity assisted flexion. Your therapist will help you with these activities.

– Patella Mobility: Moving the patella (kneecap)with glides will help prevent scar tissue formation. You do this by moving the patella up/down and in/out.
EXERCISES
– No Resistance:
  • Quad sets
  • Straight leg raises
  • Hip abduction/adduction/flex/extension
  • Knee flexion/extension (standing and prone)
  • Short arc quads
  • Toe raises
  • Semi-squats
  • Tilt board/balance board
– Stationary Bike:
  • The stationary bike is one of the most useful tools that you can use during your recovery
  • Begin with minimal resistance and emphasize pedaling circles (pushing and pulling) so that you are working both the quadriceps and the hamstring muscle groups
  • You may gradually increase the resistance as your strength and conditioning improve
  • Walking
  • As you are able to wean off crutches and out of brace, walking on flat and level surfaces is an excellent form of rehabilitation.
– Pool Therapy:
  • If you have access to a pool, you can perform many of your exercises in the pool including walking, standing knee flexion, squats and toe raises.

 

Phase 3 – Functional Training – Weeks 9-16 

GOALS:

  1. Obtain full flexion to 130-135 degrees
  2. Maintain normal gait with knee extension on heel strike
  3. Progress to functional rehabilitation
EXERCISE:
– Continue all exercises from Phase 2 and incorporate progressive resistance

Running (**Patients should demonstrate normal gait pattern, excellent quad control and hamstring strength prior to running)

  • Begin in pool and progress as tolerated to flat even surfaces
  • Backward running
  • Sprint work
  • Gradually build up speed and slow down gradually
  • No sudden starts or stops

Jump Rope: Begin with 3 to 5 minutes and progress to 10 to 15 minutes with varying footwork

Jumping Drills: Bilateral box jumps, single leg jumps and landings

Skill and Agility Drills: Side-steps, Carioca, Figure of 8’s large and small, shuttle runs, one leg hops

 

Phase 4 – Sports Specific Training – 5-6 Months

Functional Training
– Sport Specific Training
RETURN TO SPORT BETWEEN 6-9 MONTHS
-Your release to sports and other activities that involve pivoting, twisting and cutting will be determined by Dr. Jones
– Things I will consider in this release include:

  • A Stable Knee
  • Adequate completion of rehabilitation protocol
  • Quadriceps girth measurement within 1 cm of opposite side
  • Quadriceps and Hamstring strength at least 80% of opposite side
  • At times I will request a functional test to be performed by your Physical Therapist.
