Meniscal transplantation can alleviate pain and swelling in meniscus-deficient patients, potentially preventing further joint degeneration. Early intervention is recommended, especially before advanced cartilage damage occurs.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Regenerative Medicine

Background:

  • Meniscal deficiency can lead to progressive joint degeneration and pain.
  • Meniscal allograft transplantation is a potential solution for selected patients.
  • Absence of the medial meniscus increases stress on anterior cruciate ligament grafts.

Purpose of the Study:

  • To evaluate the efficacy of meniscal transplantation in preventing joint degeneration.
  • To identify patient selection criteria and contraindications for meniscal transplantation.
  • To assess early outcomes of meniscal allograft transplantation.

Main Methods:

  • Patient evaluation using standing long-leg radiographs and MRI for cartilage assessment.
  • Use of fresh-frozen and cryopreserved allografts.

  • Graft sizing based on radiographic tibial plateau measurements.

    • Main Results:

    • Early results show improvements in pain, swelling, and knee function.
    • Poor outcomes are associated with advanced cartilage degeneration.
    • Degeneration of the posterior horn of the transplant is sometimes observed.

    Conclusions:

    • Meniscal transplantation is a viable option for selected meniscus-deficient patients to prevent further joint degeneration.
    • Careful patient selection, including assessment of cartilage health and alignment, is crucial.
    • Earlier transplantation in cases of known meniscal deficiency may yield better results.
