Proper Cartilage Status for Meniscal Allograft Transplantation Cannot Be Accurately Determined

Purpose: To evaluate if pre-operative patient clinical evaluation scores accurately reflect the cartilage status in a patient who has undergone a lateral meniscectomy and has progressed to lateral meniscal allograft transplantation.

 Summary:

  • 113 consecutive patients underwent lateral MAT and completed the most common patient-reported outcome measures: VAS, IKDC Subjective, Lysholm and Tegner Activity Scale.
  • More than half of the patients had high-grade cartilage degeneration at time of surgery even though their VAS pain scores were low
  • The majority of the patients did not experience significant pain during light activities
  • Could not find a difference in scores between patients with low-grade and high-grade cartilage degradation except with the Lysholm test (mean score only differed by 5.5 points)
  • The most commonly used outcome measures are not helpful in assessing the degree of cartilage damage

Take Away: Mild or tolerable symptoms did not always mean that the articular cartilage was well preserved; more observation should be undergone to determine possible chondral damage pre-operatively.
