Each year, between 300,000 and 500,000 meniscal surgeries are performed. Most patients recover well from these procedures, experiencing no further issues. However, a subset of individuals may develop pain or other symptoms even after surgery. This pain can occur with or without the presence of arthritis. The underlying cause of this discomfort can be multifaceted, including cartilage loss, joint malalignment or ligament damage.
For patients who continue to suffer from pain despite meniscal surgery, meniscal transplantation may be a viable option. This procedure involves replacing the missing meniscus with a donor meniscus, typically obtained from a human cadaver. Here’s what you need to know about meniscal transplantation:
- Procedure Overview: Meniscal transplantation is performed arthroscopically, which means it is minimally invasive and generally done as an outpatient procedure. The donor meniscus is carefully matched in size and shape to fit the patient’s knee.
- No Rejection Concerns: Unlike organ transplants, meniscal transplants do not require anti-rejection medications because the body does not recognize the meniscal tissue as foreign. This makes the recovery process somewhat simpler compared to other types of transplants.
- Evaluation and Associated Issues: Before proceeding with a meniscal transplant, patients undergo a thorough evaluation to check for additional problems such as cartilage loss, malalignment, or ligament disruptions. Addressing these issues is critical to the overall success of the transplant.
- Success Rates and Expectations: Meniscal transplantation has a success rate of 75 to 85 percent, with many patients able to return to sports and normal activities. However, it is important to note that the primary indication for the procedure is to alleviate current pain and dysfunction, not to prevent future arthritis progression.
- Longevity and Risks: The transplanted meniscus generally remains effective for 10 to 12 years, although this can vary. There is also a risk of the transplanted tissue re-tearing. Thus, while meniscal transplantation can significantly improve quality of life, it is not a guaranteed long-term solution.
Post-Operative Care and Recovery
Recovery from a meniscal transplant typically takes six to eight months. During this period, patients often use crutches and a brace, and may even require a passive motion machine to restore range of motion and nourish the newly placed cartilage. Detailed rehabilitation protocols are essential for a successful recovery, and patients should follow their surgeon’s guidance closely.
Continuing Research and Support
At Rush University’s Department of Orthopedic Surgery, we are at the forefront of orthopedic research. Our team of surgeons, clinicians, and researchers work collaboratively to develop new treatments and improve patient outcomes. Our research efforts are supported by generous donors, patients, and families who believe in advancing musculoskeletal care.
