Clinical Report: Surgical Approaches for Degenerative Meniscus Lesions
Overview
Degenerative meniscus lesions (DMLs) are common in middle-aged and older adults, often associated with knee osteoarthritis. Despite widespread use of arthroscopic partial meniscectomy (APM), randomized controlled trials have generally shown no significant benefit over non-operative treatments, prompting the 2016 ESSKA consensus to provide a balanced framework for management.
Background
DMLs develop slowly, typically involving horizontal cleavage in patients over 35 years without trauma history. Their prevalence increases with age, affecting over 50% of men aged 70–90 years. MRI commonly reveals intrameniscus hypersignals due to mucoid degeneration. Although APM is frequently performed, concerns remain about its efficacy and the risk of subsequent osteoarthritis. The ESSKA consensus project aimed to reconcile clinical practice with evidence from randomized trials to guide treatment decisions.
Data Highlights
Prevalence of DMLs increases with age: 16% in women aged 50–59 years and over 50% in men aged 70–90 years. Incidence of surgical meniscus procedures doubled in Denmark from 164 to 312 per 100,000 persons between 2000 and 2011. Multiple RCTs since 2002 show no additional benefit of APM compared to non-operative or sham treatments at short- and mid-term follow-up.
Key Findings
DMLs are degenerative lesions occurring without trauma in patients older than 35 years.
APM is widely performed but RCTs generally do not demonstrate superiority over conservative management.
There is a high risk of osteoarthritis development following APM.
Clinical practice shows increasing rates of meniscus surgery despite evidence favoring non-operative treatment.
RCTs have limitations including crossover to surgery, complicating interpretation.
The ESSKA consensus provides a framework combining scientific evidence and expert opinion rather than strict guidelines.
Clinical Implications
Clinicians should carefully consider non-operative management as the first-line treatment for symptomatic DMLs, especially given the lack of clear benefit from APM and the risk of osteoarthritis progression. Surgical intervention may be reserved for selected cases where conservative treatment fails or mechanical symptoms persist. The ESSKA consensus supports individualized patient care guided by both evidence and clinical expertise.
Conclusion
The 2016 ESSKA consensus highlights the need for a balanced approach to managing degenerative meniscus lesions, emphasizing non-operative treatment while recognizing the role of surgery in specific clinical scenarios. This framework aims to optimize patient outcomes and reduce unnecessary meniscectomies.
