In this circumstance, an athlete sustains a reinjury to their knee with the ACL graft being torn. When all factors have been evaluated, an assessment can then be made if a one stage or two stage reconstructions are necessary. Study results presented today at the 2008 American Orthopaedic Society for Sports Medicine's Annual Meeting in Orlando, Fla., have found that ACL reconstructions that use cadaver tissue fail in 23% of patients younger than 40. In severe cases, the tendon can retract significantly causing a palpable gap on examination along the tendon course. I was told by one of the orthopedic surgeons that I worked with that I would never run again and would be lucky if I could ever hike again. Thus, consideration for bone grafting when the tunnels are too large or when the tunnels would overlap with a properly placed tunnels for a revision ACL reconstruction should be considered in all patients. ACL surgery can fail, even in the best of circumstances. Other causes of ACL graft failures include a lack of a medial meniscus, because the medial meniscus is an important stabilizer to preventing the knee from slipping forward in an ACL deficient knee. A repair using cadaver or donor tissue is called an allograft ACL repair.” The graft sources are similar for both procedures. Dr. La Prade had just moved to Vail and I was his 2nd patient @ The Steadman Clinic. Reasons for early allograft failure could include an immune response and lack of graft incorporation, a too early return back to high level activities prior to graft incorporation or issues with the graft itself to include unrecognized tearing within the graft or use of irradiation to sterilize the graft (which has been shown to increase the risk of graft failure). Thus, the work-up for ACL revision surgery has to include an evaluation of biology, evaluation of the patients alignment and their secondary restraints, a careful assessment of the posterior horn of the medial meniscus and also an evaluation of the previous reconstruction tunnel placement and size. This is believed to be the main reason why allografts fail up to 45-50% of the time in patients that are less than 25 years of age. The principle reasons for failure are permanent stiffness of the knee manifested by lack of full extension, and recurrent instability or giving way. When there is no medial meniscus, an ACL graft would be at risk for stretching out. The short answer at this time is no. In addition, there is not a blood supply that goes through an ACL graft, again, like a large organ would be transplanted and so, you do not have to have anti-rejection … Has n… You can schedule an office consultation with Dr. LaPrade. We also keep them in an ACL brace to protect their knee against any undue forces with twisting, turning or pivoting until at least the 6-month point. Donate It. “Because the actual ACL tendon is a very small piece of tissue inside the joint, we don’t use a cadaver ACL tendon for repairs; it’s too short,” says Dr. Pepin. So how do you decide which type of ACL graft is best for you? - Dr. Matava (VIDEO), After ACL Surgery, When Can Women Return To Work? See ACL Tear Surgical Repair. A large number of studies have indicated that the use of cadaver grafts (allografts) in younger patients have a much higher risk of failure. Both graft types remain viable options for primary ACL reconstruction, and the difference in failure rate should be one part of a larger conversation with each individual patient about graft selection that should also include potential differences in donor site morbidity, complication rates, and patient-reported outcome measures. For that reason, misplaced graft reconstruction tunnels are still a very common cause of an ACL reconstruction failure. Together with my team of researchers, I have spent nearly three decades studying the causes of failure of knee ligament reconstructions and the outcome of revision operations using a variety of graft materials.. (Please keep reading below for more information on this treatment.). In addition, there is not a blood supply that goes through an ACL graft, again, like a large organ would be transplanted and so, you do not have to have anti-rejection medications. Clinical symptoms can include pain, failure to toe off and trouble walking up-hill or along an incline. This type … It is felt that a 3 mm increase in anterior tibial translation compared to the contralateral knee is indicative of a nonfunctional ACL reconstruction graft. However, the majority of ACL reconstructions performed in the United States are performed by surgeons who perform ten (10) or less each year. You may be a candidate for an ACL Revision Reconstruction. Patients that do not have arthritis and can perform a single-leg squat with no valgus collapse may be considered for initiation of a jogging or running program starting at 4 months postoperatively. - Dr. Matava (VIDEO). A very careful assessment of the cause of the graft failure is necessary to try to maximize an individual patient’s outcome with an ACL revision surgery. There are certain times when trying to perform a one stage ACL reconstruction may significantly increase the risk of failure of the revision graft. Request Case Review or Office Consultation, Lateral Patellotibial Ligament Reconstruction, Biomechanical Comparsion of Anatomical Single and Double Bundle ACL Reconstruction, Femoral Cortical Suspension Devices for Soft Tissue ACL Reconstruction, Biomech Comparison of Tibial Fixation for Soft Tissue ACL Grafts on the Tibia, Effects of Grade III PLC Injuries on ACL Grafts. An ACL reconstruction is one of the most common surgical procedures in orthopaedic surgey. The anterior cruciate ligament(ACL) is important for maintaining stability of the knee joint, particularly in activities involving weaving, pivoting or kicking. - Dr. ... ACL Reconstruction, What Is The Success Rate? • The allograft tissue is thoroughly tested for diseases. Patients may have swelling with activities also. Thus, one has to use caution to ensure that there is sufficient ability for the ACL graft to heal. First, if an athlete returns to competition prior to having full endurance, proprioception, strength and agility, they are at risk for an ACL reconstruction failure even if the graft is perfectly placed. An individual can receive an organ donation from an animal (such as a pig heart valve) or donate tissue to themselves by moving healthy tissue from one part of their body to another (such as skin grafting). Sometimes these grafts may even look “normal” on an MRI scan. This is because the blood supply is not as good in a revision reamed tunnel as the first time around and biology seems to greatly affect ACL graft healing. - Dr. Matava (VIDEO), When The Meniscus Is Removed, What Happens To The Knee? If left untreated, the natural history of an ACL-deficient knee can result in recurrent instability, inability to return to full athletic activity, meniscal tears, and articular cartilage damage.27 Therefore, the goals of ACL Issues that can occur with an ACL reconstruction surgery include fractures of the lateral femoral condyle, for which we have published peer-reviewed case reports on, breaking out the back wall, or soft bone which hinders fixation. They wear an ACL brace through 6 months postoperatively to ensure that they do not have extra forces on their ACL when they twist, turn, or pivot. Has your ACL reconstruction surgery failed? That certainly can happen. Most surgeons who perform ACL revision surgery obtain CT scans of the patient’s knee to assess the original ACL reconstruction tunnel location and size. A 30-year-old patient complained of certain symptoms, such as an inability to focus mentally, rash on the right femur, chronic fatigue, decreased sex drive, and localized alopecia, 3 months after ACL reconstruction in the right knee. Find allograft rejection information, treatments for allograft rejection and allograft rejection symptoms. Thus, ACL revision rehabilitation programs tend to be more conservative and advance slower to give the best chance for the ACL graft to heal.
