Physical Therapy vs Surgery for ACL Injuries


Trauma to the ACL (anterior cruciate ligament) is a common sports tear that can be debilitating and in some cases career-ending for people in professional sports.

ACL is a key knee connective knot that joins the thigh bone to the shinbone. Risk for ACL injury is increased for some sports than for others. ACL ruptures are most frequent in kinds of sports like football, basketball, soccer, ice hockey.

It is increasingly common for docto prevent long run effects such as osteoarthritis and menisci tears. However, there is mounting evidence that conservative handling of ACL injuries, including physical therapy, are just as effective in resolving this type of trauma. Furthermore, conservative treatment for ACL injury is reversible, while the surgery is permanent.

The Research

There are a plethora of experimental studies and reviews that address the topic of surgery vs ACL PT post-injury. The most impressive studies are described below as follows.

  • The first of the two studies depicts the difference between the early post-trauma operational reconstruction of the ligament with the conservatively treated (rehabilitated) post-trauma ACl.
  • 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. The first and the second group of patients improved knee health over two years’ time. Groups were very similar per se. In more than half of the patients the joint healed up and the surgery was avoided.

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 of people that went for early post-trauma reconstruction did not lead to better results.

The follow-up study by the same authors came back to developing side effects. Five years after treatment, half of the early rehab group did not need the surgery at all.
Regardless of whether ACL patients elect to play after ACL rupture.

In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
