These injuries have been reported to change joint loading due to failure of the meniscus to convert axial loads into hoop stresses. Treatment or management protocols for posterior horn menial meniscus tears are quite challenging. what is the treatment? I have been diagnosed with a subtle oblique tear involving the posterior horn of the medial meniscus and extends to the inferior articular surface of the meniscus. 3 Thornton DD, Rubin DA.

Common tears include bucket handle, flap, and radial. McMurray (Figure 1) and Apley tests (Figure 2) are often positive, although these are specific but not sensitive specificity being 5798% and 8099%, and sensitivity being 1066% and 1658% respectively.2,9 The most useful clinical test for meniscal injury is the Thessaly test, which is demonstrated in Figure 3.

Know why a new medicine or treatment is prescribed, and how it will help you. Historically, medial meniscal root tears have been treated conservatively or by partial meniscectomy. 2.

Presumptive subarticular stress reactions of the knee: MRI detection and association with meniscal tear patterns. Repair is sometimes attempted even with these tear types, particularly when the patient is young and substantial loss of meniscal tissue would lead to an unacceptable risk of future arthritis.11 Repair of these challenging tear types should only be attempted when the meniscal tissue is of good quality and a stable result is achievable.

Depending on your duration of symptoms you can at least start off with physical therapy, a knee sleeve, and if there is arthritis present consider a c Dr. Christopher Ferguson and another doctor agree.
