medial and lateral menisci Flashcards
What are the medial and lateral menisci attached to?
The medial and lateral menisci are firmly attached to the proximal surface of the tibia.
How do the thicknesses of the menisci vary?
The menisci are thick at the periphery and thinner at their internal unattached edges.
Which meniscus is more commonly injured?
The medial meniscus is more commonly injured than the lateral meniscus.
Why is the medial meniscus less mobile
The medial meniscus is less mobile due to its attachment to the joint capsule.
What methods are used to definitively diagnose meniscal injuries?
Meniscal injuries are definitively diagnosed by arthroscopy or magnetic resonance imaging.
What happens to the incidence of medial meniscal tears over time with ACL deficiency?
The incidence of medial meniscal tears increases significantly over time with ACL deficiency.
What is the common etiology of meniscal injuries?
Meniscal injuries are usually associated with fixed foot rotation while weight bearing on a flexed knee.
What is the initial treatment approach for meniscal injuries?
The initial treatment includes RICE (Rest, Ice, Compression, Elevation), NSAIDs, and analgesics as needed.
What special tests can identify the presence of a meniscus tear?
Special tests include Apley’s compression test, bounce home test, and McMurray test.
What clinical signs and symptoms are associated with meniscal injuries?
The clinical presentation includes joint line pain, swelling, catching, or a locking sensation.
What does conservative treatment for meniscal injuries consist of?
Conservative treatment consists of palliative modalities and strengthening exercises.
Where are meniscal repairs typically performed, and why?
Meniscal repairs are typically performed on tears located on the outer edges of the meniscus due to the increased vascularity.
What surgical options are available for active individuals with meniscal injuries?
Surgery can range from a partial meniscectomy to a meniscal repair for active individuals.
What recent advances have influenced meniscal surgery?
Recent advances in technology have increased the incidence of meniscal transplantation.
