Derrick Rose Has Knee Surgery to Repair his ACL Tear
As most sports fans know… both Derrick Rose and Mariano Rivera recently sustained ACL tears. The ACL is the anterior cruciate ligament and for those interested, this short knee anatomy video will show you the structure of the knee, and more specifically the ACL.
After a course of “pre-habilitation” Derrick Rose recently underwent surgery to repair his ACL. The Chicago news media reported that the surgeon chose a patella tendon graft and also elected to perform a PRP or Platelet Rich Plasma injection at the time of the surgery. Let’s look at these aspects of his ACL surgery and events leading up to it more closely.
Rehabilitation Before Surgery:
Most surgeons recognize the benefit of pre-hab or physical therapy before surgery. The focus of pre-hab is to:
- Allow for the swelling to subside
- Decrease the inflammation within the knee
- Let you get back some of the lost strength in the muscles supporting the knee.
A more flexible, less painful knee before ACL knee surgery, leads to less swelling, less inflammation and hopefully an easier recovery after ligament surgery for an ACL tear.
Graft Choices for an ACL Ligament Reconstruction:
As surgeons we have many graft choices available to reconstruct or rebuild your ACL tear. These include:
Autografts (your own tissue):
- Hamstring Tendons: Where we use two (of four) of your tendons to create the new ACL.
- Quadriceps Tendon: Where we take a portion of your quadriceps tendon (above the kneecap)
- Patella Tendon: Where we take the central 1/3 of your patella tendon (below your kneecap)
Allograft: (Cadaveric tissue, or tissue from someone who has passed on and donated their tissues for medical use)
- Patella Tendon
- Quadriceps Tendon
- Achilles Tendon
- Hamstring Tendons
- Other tendons from the leg
The most important factor is not necessarily which tissue you chose to use for your ACL reconstruction eg: patella tendon vs. hamstring tendons. The bigger decision is whether or not to use autograft or your own tissue, versus allograft, which is from a cadaver. There is recent scientific literature which reveals a higher re-tear rate in children if an allograft is used versus autograft.
PRP or Platelet Rich Plasma:
PRP, or platelet rich plasma is a portion of your blood that we prepare by taking a sample of your blood, approximately 30-60cc, and then that blood is placed in a centrifuge for 15 minutes. After that the blood separates into different layers or components. One of those layers contains the platelets, which are cells which contains a number of growth factors and chemicals which initiate a reaction by the body to repair the area where the platelets are.
PRP has proven to be useful in the treatment of tennis elbow, and other tendon related disorders. PRP is also being actively investigated to determine if it is useful in improving the healing time after surgery. While PRP is a well accepted treatment for certain tendon or muscle problems and has become very popular, there is less certainty as to whether or not it is useful when used at the time of surgery.
Hopefully Derrick Rose continues to recover well from his recent ACL reconstruction!
