Failed Meniscus Repair

What is a Meniscus Repair?

The meniscus is a segment of crescent-shaped cartilage in your knee that acts as a cushion between the femur (thigh bone) and tibia (shin bone). A meniscus repair is a surgical procedure aimed at stitching torn meniscal tissue together to restore its function and prevent long-term joint damage.

A failed meniscus repair occurs when the repaired tissue does not heal properly, re-tears, or continues to cause pain and dysfunction after surgery.

  • Poor blood supply to the tear location (especially in the inner “white zone”)
  • Re-injury or trauma to the knee during recovery
  • Non-compliance with rehab protocols (e.g., returning to sports too soon, early weightbearing)
  • Complex or degenerative tears that have poor healing potential
  • Incorrect diagnosis or surgical technique
  • Underlying joint conditions, such as arthritis

  • Persistent or recurrent knee pain
  • Swelling or stiffness in the knee
  • Locking, clicking, or catching sensations over the torn meniscus
  • A feeling of instability or giving way
  • Limited range of motion
  • Pain during twisting, deep squatting, or weight-bearing activities

Evaluation of a failed meniscus repair includes:

  • History & Physical Exam: Assessment of knee symptoms, swelling, location of tenderness, and mobility.
  • Imaging Studies:
    • MRI: Most accurate for visualizing meniscal integrity and surrounding structures. Effective but some meniscus tears may not be seen
    • X-rays: Rule out other joint pathology, osteoarthritis, and assess joint health
    • Arthroscopy: Occasionally used to confirm diagnosis directly if imaging and exam are inconclusive

Non-Surgical Management

Often trialed initially. For mild symptoms, or low activity patients:

  • Physical therapy: Strengthening the muscles around the knee to improve stability
  • Anti-inflammatory medications (NSAIDs)
  • Activity modification: Avoiding high-impact or twisting movements during early rehab
  • Knee braces or supports to help with function initially. Will discontinue as knee strength improves
  • Corticosteroid injections (for pain and inflammation)
  • Viscosupplementation (in select cases)

For active patients or those with ongoing symptoms:

Revision Meniscus Repair

  • Suitable if the tissue is still viable and located in a vascular region
  • Often combined with biologics like PRP or bone marrow aspirate to improve healing

Partial Meniscectomy

  • Removal of the damaged portion of the meniscus
    • Indicated if meniscus tissue cannot be repaired or has poor healing potential
  • Faster recovery, but increased risk of long-term arthritis

Meniscus Transplantation

  • In select younger patients with total meniscus loss
  • Requires strict selection criteria and is less commonly performed
    • Contraindicated if there is moderate to advanced osteoarthritis

Adjunctive Procedures

  • ACL reconstruction, osteotomy, or cartilage restoration may be needed if other pathology is present

  • Recovery depends on treatment chosen, age, activity level, and knee health
    • Slower recovery is often expected given that this is a revision procedure
  • Rehabilitation is crucial—adhering to physical therapy and weightbearing protocols is vital to having a good outcome

Contact your orthopedic provider if you experience these symptoms after a meniscus repair:

  • New or worsening knee pain
  • Swelling that does not improve
  • Difficulty walking or bearing weight
  • Clicking, locking, or instability symptoms
