Understanding the Timeline: How Long is ACL Rehab?

An ACL injury affects physical health and overall well-being. When injured, the ACL demands a practical rehabilitation approach. Knowing what to anticipate during recovery prepares you for the journey ahead.

That’s why La Clinica’s injury care specialists have taken their time to walk through the journey and will discuss ACL recovery in this blog post.


Your knee joint relies on many bands for stability. They also ensure proper function. Ligaments are rugged and fibrous bands that connect bones. As such, providing stability and facilitating joint movement. It sits in the center of the patella joint and plays a pivotal role in maintaining its stability.


Your ACL is a crucial component of the knee and plays various roles. Let’s delve into some of its essential functions below:

Stabilizing the Knee

The first key function of the ACL is to strengthen the patella. This is especially vital during sudden stops, changes in direction, or pivoting movements. The ACL also acts as a crucial stabilizer by preventing too much forward movement of the tibia (shinbone) in relation to the femur (thighbone).

Controlling Rotation

It also contributes significantly to controlling the rotation of the knee. This crucial ligament restrains excessive twisting or turning of the joint, ensuring that the bones move in a coordinated manner.

Preventing Hyperextension

Your anterior cruciate ligament prevents this from happening and subsequently safeguarding it from overstretching or damage.

How ACL Injuries Occur

Sports Injuries

Due to soccer’s dynamic and high-impact nature, athletes are at a higher risk of these mishaps. Football and netball players may also suffer tears or damage.

Sudden Stops or Changes in Direction

Abruptly stopping or changing direction, especially when running or pivoting, can place immense stress on the ACL and lead to injury.

Overuse and Fatigue

Repetitive stress is another cause of overuse injuries. It compromises neuromuscular control and increases the likelihood of injury.

Improper Landing Techniques

Athletes who land from a jump with poor technique are at a higher risk of ACL injuries. This misalignment puts excessive stress on the ligament. Incorrect stances to watch out for include but are not limited to:

  • Knees collapsing inward upon landing
  • Landing with stiff or locked knees
  • Allowing the knees to extend beyond the toes during landing
  • Uneven distribution of weight on one leg during landing
  • Landing with the feet too close together
  • Not maintaining proper alignment of the hips, knees, and ankles during landing

Muscle Imbalances

Weakness or imbalances in the quadriceps and hamstrings contribute to cruciate ligament injuries. These muscles stabilize the knee, and their weakness may increase the vulnerability of the ligament.

Terrain and Surface Factors

Playing on surfaces with poor traction increases the risk of these injuries. So, it is best to be mindful of environmental conditions.

Previous ACL Injuries

If you have previously experienced a damaged band, you are at a higher risk of re-injury. Adequate preventive measures reduce the risk of recurrence.

Gender and Anatomic Factors

Studies suggest that females tend to get ACL injuries than males. A possible reason is differences in anatomy, neuromuscular control, and hormonal factors. Anatomic variations, such as a narrow femoral notch, may also contribute.

The Phases of ACL Rehab

Early intervention deals with the symptoms before they get out of hand. Above all, it promotes quick recovery. ACL recovery involves various multiple phases. Each is crucial in rebuilding strength, mobility, and function.

Here’s a comprehensive timeline of each phase:

Initial Recovery

The first phase focuses on managing pain and swelling. During this period, physical therapy doctors concentrate on:

  • Rest: Adequate rest is paramount to prevent further damage.
  • Ice: Cold therapy helps minimize swelling and inflammation.
  • Compression: Compression garments or wraps aid in reducing swelling.
  • Elevation: Elevating the leg assists in fluid drainage.

Your journey begins with gentle range of motion exercises to prevent stiffness. These include:

  • Ankle Pumps
  • Quad Sets
  • Heel Slides
  • Seated Knee Flexion
  • Passive Knee Extension
  • Ankle Circles
  • Stationary Bike

Regaining Mobility

In phase two, PT doctors focus on restoring the full range of motion. Expect the sessions to become more intense. Exercises now aim to strengthen the surrounding muscles. You may also begin light aerobic exercises.

Exercises your PT doctor may suggest during phase 2 include:

  • Hamstring Curls
  • Straight Leg Raises
  • Calf Raises
  • Prone Hangs
  • Mini Squats
  • Seated Leg Press
  • Stationary Biking

Building Strength

Entering the third phase, the focus intensifies on building strength. Your specialists introduce progressive resistance exercises, targeting your calf muscles and quadriceps. Your hamstrings may also get some attention. Stability programs retrain the neuromuscular system.

  • Single-Leg Balance Exercises
  • Bosu Ball Exercises
  • Step-Ups
  • Lateral Band Walks
  • Medicine Ball Exercises

Also, your PT specialist may introduce various physical therapy modalities during this phase:

  • Electrical Stimulation: Used to generate muscle contractions and aid in their re-education.
  • Ultrasound Treatment: Produces sound waves that aid healing. It also alleviates inflammation.
  • Heat Therapy: Relaxes muscles around your knee and increases blood flow to promote flexibility.

Functional Training

The rehabilitation program transitions to functional activities. Patients work on balance, agility, and sport-specific drills. In addition, specialists introduce plyometric exercises to prepare your joints for dynamic movements. Discover what your doctor might do at this stage:

  • Conduct assessments to ensure proper movement patterns and identify any lingering deficits.
  • Recommend exercises that challenge balance and agility like single-leg hops, lateral shuffles, and cutting movements.
  • Tailor exercises to mimic the movements required in the individual’s particular sport or daily activities.
  • Gradually introduce plyometrics, like jumping and quick directional changes, to enhance power and coordination.
  • While continuing to build strength, the focus shifts to maintaining the achieved strength levels through targeted exercises.
  • Fine-tune neuromuscular control for proper joint stability while preventing re-injury.
  • Incorporate sport-specific cardiovascular exercises to improve endurance.
  • Depending on the progress and individual goals, a gradual return to complete activities is initiated under the doctor’s guidance in physical therapy.

Return to Sport

The truth is that your ultimate goal is often a return to sports activities. Your team will introduce sport-specific drills so you can handle the demands of the game. The focus is increasing performance and ensuring you never get the injury again. Below is what to expect:

  • Unique exercises and drills to closely mimic the movements and intensity of the game.
  • High-intensity cardiovascular conditioning to enhance endurance and stamina specific to the sport.
  • Dynamic strength exercises and power training to prepare the muscles for explosive movements.
  • Integrating specific skills required for the sport, such as cutting, jumping, and rapid directional changes.
  • Focusing on exercises and strategies to prevent future injuries, including targeted strengthening and proprioceptive exercises.
  • Slowly reintroducing the individual to full practice sessions and competitive play. It is vital to closely monitor their response and adjust the intensity as needed.
  • Fine-tuning performance aspects, including agility, speed, and coordination, to ensure the individual is not only back on the field but performing at their best.
  • Conducting a thorough assessment to evaluate the individual’s readiness for total return, considering physical and psychological factors.
  • Even after returning to the sport, continued monitoring and periodic check-ins with the PT doctor help ensure sustained performance and address emerging concerns.

Factors Influencing Rehab Duration

Everyone’s recovery experience is unique and influenced by various factors. Understanding these factors enables specialists to tailor the plan to your needs.

Here’s what determines the duration of ACL rehab.

The Type of Surgery

The type of ACL surgery performed significantly influences the rehabilitation timeline. Each procedure yields different recovery experiences.

Traditional ACL reconstruction involves using a graft to replace the torn band. The conventional approach requires precise drilling of bone tunnels to secure the replacement. This option is effective but can result in more postoperative pain and rehab.

Less invasive procedures minimize disruption to surrounding tissues through smaller incisions and the use of specialized instruments guided by a camera. While these procedures generally lead to less initial discomfort and faster early recovery, the overall rehabilitation timeline still depends on various factors.

Individual Healing Factors

No two individuals heal equally. Individual traits determine how the body responds to the injury. Not only that, but it also affects subsequent surgical intervention. These include but aren’t limited to:

  • Age
  • Overall health
  • Genetic predispositions
  • Fitness

Younger individuals often experience a more robust healing response. Youthful tissues may recover and adapt more quickly, expediting the rehabilitation process. Conversely, older individuals may face additional challenges due to decreased collagen production and potential comorbidities.

Overall health is another crucial consideration. Those with good overall health, including adequate blood flow, cardiovascular fitness, and nutritional status, may exhibit more efficient healing.

Genetic factors like collagen structure and the body’s inflammatory response also determine how your body responds to injury. Thanks to such crucial details, healthcare professionals tailor rehabilitation plans to individual needs.

Adherence to the Rehab Program

Patients who adhere diligently to their rehabilitation program will likely regain functionality soon. Specialists carefully design the rehabilitation plan to progress through specific phases. Each targets different aspects of recovery. Regular engagement in exercises, both during supervised sessions and alone at home, promotes muscle strength, joint flexibility, and overall functional improvement. 

Remember to follow up with PT experts for progress evaluations, scheduled appointments, and assessments, which are also vital.  Attending these appointments empowers the experts to monitor your recovery milestones. They also allow for the adjustment of the rehabilitation plan as needed and address any emerging concerns.

Psychological Factors

The psychological challenges that often accompany cruciate ligament damage, such as fear of re-injury, frustration, or anxiety about the timeline, influence your engagement in the process.

Patients who approach the process with a positive attitude and a strong mental outlook more often than not stay committed to the program. However, persistent negative thoughts or emotional barriers can hinder progress and potentially lead to setbacks.

Healthcare professionals work collaboratively to support patients in addressing psychological factors.
