Is Knee Ligament Surgery Right For You?
Knee ligament surgeries have become quite common, ACL (anterior cruciate ligament) surgeries average 250,000+ surgeries alone every year (1)! These invasive surgeries have come under investigation in recent years, wondering the necessity, or need to be done. Today lets understand the knee a little better and take a look at the need for a knee ligament surgery, in addition, look into alternative treatments.
Your knee has 3 points of contact or compartments that house the cartilage of your knee:
- Patella Femoral Compartment
- Lateral (outside) Compartment
- Medial (Inside) Compartment
These compartments are held together by a network of ligaments that hold each bone together and allow the knee to move properly.
Four Principle Knee Ligaments
There are four principle ligaments (2):
- Anterior Cruciate Ligament (ACL),
- Posterior Cruciate Ligament (PCL),
- Medial (inside) Collateral Ligament (MCL), and
- Lateral (outside) Collateral Ligament (LCL).
The collateral ligaments provide stability (3). You can think of these ligaments as the glue that holds the knee together, or even the lug nuts that keep your knee together! The 2 most commonly torn ligaments of these are the MCL and ACL (4).
The most important of these ligaments is your ACL. In addition to providing stability to the joint, your ACL acts as a ‘proprioceptive organ” (4). Meaning the ligament has a direct connection to your nervous system via sensory receptors that monitor your knee position. If these sensors sense that the knee is in a bad position, it will activate your nervous system to contract the muscle around the knee to protect the knee as a protective reflex.
Can a knee ligament heal without surgery?
The MCL is the most injured ligament of the knee and the ACL is the most commonly injured ligament in conjunction with the MCL. Most MCL injuries can be treated non-operatively (9). Even though the MCL can spontaneous heal without any additional treatment, the healing that does take place is typically incomplete (11) which can increase the risk of re-injuring the ligament over time.
A precise concentration of bone marrow concentrate can be a better alternative to waiting for body’s natural healing response to kick in. You can see in before and after treatment that there is near complete healing of the MCL.
ACL reconstruction has become a standard of care for most ACL tears because the spontaneous healing rate of ACL’s is less than 5% (10). But at The Centeno-Schultz Clinic we have created a novel treatment for ACL tears to prevent the need for a knee ligament surgery! Utilizing your own body’s stem cells, we can harvest and concentrate the cells, then precisely inject them into the injured ligament. This injection of your own healing cells allows your body to regenerate the ligament and effectively preventing the need for a knee ligament surgery! We have published multiple peer reviewed research papers demonstrating 7 to 8 out of 10 patients with an ACL tear can avoid the need for knee ligament surgery!
How long is recovery from knee ligament surgery
The main knee ligament surgery that is the most heavily researched is ACL reconstruction (5). Rehabilitation after reconstruction is key but the rehab course is extensive, taking 9-12 months to complete (5-8)! Postoperative rehabilitation should continue for 9-12 months. During the rehabilitation, there are notable complications and side effects that present. Re-injuries, reduced strength in both quadriceps and hamstrings. Loss of proprioception and up to a quarter (1 out of 4) will lose range of motion in both flexion and extension.
Comparing the recovery from the invasive surgery, our novel treatment has seen rehabilitation and return to activity reduced by 50%!
Is ACL surgery a major surgery
While most patients do well in the short term with ACL reconstruction surgery, many orthopedic surgeons fail to discuss the long term consequences of having the knee ligament surgery.
- 60% of patients will develop meniscal damage
- Loss of proprioception
- Loss of knee range of motion 23% of the time
- Quadriceps atrophy in a third of patients
- Hamstring weakness
- Chronic front of the knee pain in 50% of patient who have patella tendon graft
The worst is that within 15 years from surgery you will develop progressive knee arthritis and eventually be a candidate for a knee replacement
Here is a the latest video on the current treatment options for ACL tears:
Can you still walk with a torn ligament in your knee?
Yes, you can still walk with a torn ligament but without one (or even two) of your main knee ligaments, walking and simple activities can become difficult. This highlights the need for a good physical therapist that can help you activate the muscles around the knee to allow a more functional knee! Therapy is critical to help reduce the atrophy and help the motor control. There are some individuals that are able to continue without the need of a knee ligament surgery or a stem cell treatment where they can return to athletic activity, adapting without the ligament. We refer to these patients as “copers” (12). These are patients that can return to activity after a progressive rehabilitation with physical therapist without pain or instability BUT research on biomechanics continues to show alterations in the normal mechanics of the knee. Meaning that while these patients are still at risk for additional complications such as Meniscal tears and post traumatic arthritis!
Knee ligament surgeries are not simple and have long term consequences. We have created a treatment options for the majority of ACL and MCL tears to help our patients recover faster and get back to doing what they love sooner without the consequences of more invasive knee ligament surgeries! If you have had a knee ligament injury or other injury and would like to be evaluated, please contact the link below and our staff will be happy to get you set up to see if are a candidate for treatment.
