Glossary

Likelihood ratio for negative test

How many times more likely you are to not have a meniscal tear if you have a negative test compared with someone who has a positive test.

Likelihood ratio for positive test

How many times more likely you are to have a meniscal tear if you have a positive test compared with someone who has a negative test.

Musculoskeletal clinician

Orthopaedic specialist knee surgeon or extended scope physiotherapist with specialist knee interest (operating in a secondary care orthopaedic setting).

Negative predictive value

The proportion of patients with a negative test who do not have a meniscal tear.

Odds ratio

Diagnostic odds ratio of a test is the ratio of the odds of positivity in subjects with a tear relative to the odds in subjects without a tear. It is calculated according to the formula: odds ratio = (true positive/false negative)/(false positive/true negative).

Positive predictive value

The proportion of patients with a positive test who actually have a meniscal tear.

Primary care clinician

General practitioner- or community-based physiotherapist.

Sensitivity

The proportion of those patients with a meniscal tear who are correctly identified as positive by the test. Low sensitivity indicates a high rate of false-negative tests.

Specificity

The proportion of those patients without a meniscal tear who are correctly identified as negative by the test. Low specificity indicates a high rate of false-positive tests.
