Physical Therapy vs Surgery for ACL Injuries

Physical Therapy vs Surgery for ACL Injuries Blog

Damage to the anterior cruciate ligament (ACL) is a common sports injury that can be debilitating and in some cases career-ending for athletes.

The ACL is a major knee ligament that connects the femur to the tibia. Risk for ACL injury is higher for some sports than for others. ACL ruptures are most common in high-risk sports like football, basketball, hockey and soccer.

It is increasingly common for doctors to steer injured athletes with ACL ruptures toward quick surgery, hoping to prevent long-term consequences such as osteoarthritis and menisci tears. However, there is mounting evidence that conservative management of ACL injuries, including physical therapy, are just as effective in resolving the injury. Furthermore, conservative treatment for ACL tears is reversible, while ACL reconstructive surgery is permanent.

The Research

There are a plethora of experimental studies and reviews that address the topic of surgery vs physical therapy after ACL injury. Two of the most compelling come from Frobell et al. (2010 and 2013).

  • In the first study, researchers performed a randomized controlled trial to compare early ACL reconstruction to early rehabilitation with optional delayed ACL reconstruction. Participants were 121 injured athletes with a mean age of 26. The athletes were evaluated at three, six, 12 and 24 months, using outcome measures of pain, function, osteoarthritis measures and other tests. Both groups improved in all measures over the course of two years. There was no significant difference between the two groups. In 61% of the rehab group, surgical reconstruction was avoided without compromising results. The research team concluded that early ACL reconstruction did not lead to better outcomes than rehabilitation with optional delayed ACL reconstruction.
  • The follow-up study by the same authors revisited the athletes after five years and found no difference between the two groups. However, athletes who received a patellar graft for ACL reconstruction had a higher incidence of patellofemoral osteoarthritis. Five years after treatment, 50% of the early rehabilitation and optional reconstruction group did not need ACL reconstruction

Regardless of whether ACL patients elect to have surgery, or to pursue conservative treatment, physical therapy plays a key role in restoring knee function, increasing an athlete’s chances of returning to play after ACL rupture.

Planks and Crunches for Abdominal Diastasis: Totally Tabu, or OK for You?

Abdominal diastasis, known clinically as diastasis recti abdominis, or DRA, is the separation that occurs along the midline of the rectus abdominis, or RA (the six-pack muscle) during and after pregnancy. As the fetus grows, the linea alba, the connective fascial tissue that binds the right and left halves of the RA, thins and stretches […]

Fibromyalgia vs Myofascial Pain Syndrome: Are they related?

Chronic pain syndromes like fibromyalgia and myofascial pain syndrome (MFS) are often confused, and sometimes painted by uniformed practitioners with the same broad brush. Consequently, some patients with MFS may be misdiagnosed with fibromyalgia, and vice versa. However, while the two syndromes share pain as a common denominator, the origins of pain differ, as does […]
