Treating a meniscus tear: options based on your profile

Medical treatment: when it is considered as a first-line option

For stable degenerative tears, the HAS recommends medical treatment as the first step before any surgical decision. This approach aims to reduce pain and restore knee function without surgery. It relies on several components: physical therapy to strengthen the knee's stabilizing muscles, pain relievers and anti-inflammatories prescribed by a doctor, and, if necessary, temporary offloading. The methods and duration are determined by the doctor or surgeon based on the clinical presentation.

Certain stable traumatic tears can also benefit from medical treatment. When the tear is located in the vascularized zone of the meniscus (the peripheral third), spontaneous healing is possible, especially in young patients. Medical treatment allows time for the injury to evolve before deciding on an intervention.

When symptoms persist despite well-managed medical treatment, the question of surgery is revisited. This common situation is one where the decision should be weighed carefully: verifying that the diagnosis is well-established before considering surgical treatment is a step that can prevent premature decisions.

As a guide, here is how institutional recommendations steer the decision based on your profile:

• Stable degenerative tear, patient over 50: recommended first-line medical treatment (HAS). ‍
• Degenerative lesion with failed medical treatment: surgery considered, partial meniscectomy in most cases. ‍
• Stable traumatic lesion, young patient: medical treatment possible to allow spontaneous healing depending on the location. ‍
• Unstable traumatic lesion, young patient (bucket-handle tear, vascularized zone): prompt surgery considered, meniscal repair preferred if criteria are met.

Partial meniscectomy or meniscal repair: two techniques with very different implications

When surgery is indicated, it is performed via arthroscopy (minimally invasive surgery performed under anesthesia, most often on an outpatient basis). Two techniques are possible, with very distinct indications and long-term implications.

• ‍Partial meniscectomy involves removing only the damaged, unstable, or painful portion of the meniscus. This is the most common technique. It is indicated for degenerative lesions that have not responded to medical treatment, irreparable tears, or unstable lesions, regardless of age. Recovery is generally faster. Important note: reducing the volume of the meniscus, even partially, increases stress on the articular cartilage, which may accelerate the onset of osteoarthritis in the long term. This risk is particularly significant in younger patients. ‍
• Meniscal repair aims to fix the tear to preserve the entire meniscus. The criteria for this procedure are stricter: the patient must be young, the tear must be recent and located in the vascularized zone of the meniscus (where healing is possible), and the knee must not show signs of advanced osteoarthritis. The failure rate is higher than that of a meniscectomy, and rehabilitation takes longer. When successful, however, the long-term benefits for joint preservation are superior. ‍
• Meniscal transplantation is a rare option, considered for certain young patients following a total meniscectomy. It requires an evaluation by a knee surgeon specializing in this technique.

A guiding principle, recognized by the HAS and SOFCOT, informs all these decisions: preserve as much meniscal tissue as possible. This rule of meniscal preservation has gradually become the standard in light of findings regarding the long-term consequences of overly extensive meniscectomies.

The choice between repair and meniscectomy is a precise technical trade-off, on which two knee surgeons may have different approaches depending on their analysis of the case. Before committing to a surgical decision, it can be helpful to have the complete file evaluated by a second specialist.

Therapeutic decision-making: patient-specific factors

The treatment decision is not based solely on the MRI. It incorporates factors specific to each patient, which the surgeon evaluates during the consultation:

• Age and joint longevity: for a young patient, the choice between repair and meniscectomy will have consequences for decades to come. For a patient over 50, other factors come into play (the condition of the cartilage, the presence of associated osteoarthritis). ‍
• Sports and professional activity: A high-level athlete, a manual laborer, and a sedentary individual will have different functional requirements. ‍
• Actual functional impairment: The intensity of symptoms, their impact on daily life, and the response to any medical treatment guide the decision. ‍
• Associated injuries: An ACL tear or early-stage osteoarthritis changes the overall surgical strategy.

There is no universal protocol. Two patients with identical MRI findings may legitimately receive different recommendations based on these parameters. This is precisely what the French Arthroscopy Society emphasized in 2019: the decision must be based on a precise and individualized assessment. Having your entire file analyzed by a specialized knee surgeon ensures that the chosen approach is tailored to your personal situation and that all options have been carefully weighed.
