The function, pathology, and surgery of the meniscus.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Knee Biomechanics

Background:

• The menisci are crucial for knee joint function and articular surface protection.
• Meniscal tears are prevalent but frequently asymptomatic, complicating diagnosis.
• Clinical diagnosis of meniscal tears is often unreliable.

Purpose of the Study:

• To evaluate the diagnostic accuracy of imaging modalities for meniscal tears.
• To assess the relationship between meniscal tears and osteoarthritis.
• To compare the outcomes of different meniscal surgical interventions.

Main Methods:

• Review of diagnostic techniques including arthrography and arthroscopy.
• Analysis of clinical data correlating meniscal tears with joint degeneration.
• Comparison of outcomes following total meniscectomy versus partial meniscectomy.

Main Results:

• Arthroscopy and arthrography significantly improve the accuracy of meniscal tear diagnosis.
• A direct causal link between meniscal tears and osteoarthritis is difficult to establish.
• Partial meniscectomy effectively alleviates mechanical symptoms and preserves meniscal function.

Conclusions:

• Arthroscopic partial meniscectomy is an efficient and effective treatment for symptomatic meniscal tears.
• Preserving meniscal rim function is key to preventing abnormal stress transfer and degenerative changes post-surgery.
• Careful clinical correlation is necessary when interpreting findings from imaging of minor meniscal tears.
