- QALY search for term
-
QALY is an abbreviation for quality-adjusted life year (or quality-adjusted life-year) and is a generic measure of disease burden.
- Quad sets search for term

Quad sets or quads sets are knee rehabilitation exercises to keep the quadriceps (quads) muscles from becoming inhibited after injury or surgery.
- Quadriceps angle search for term
-
The Quadriceps angle of the knee is a measurement of the angle between the quadriceps muscles and the patellar tendon and provides useful information about the alignment of the knee joint.
- Quadriceps atrophy search for term
-
Quadriceps atrophy is the physical wasting of the quadriceps muscle.
- Quadriceps inhibition search for term
-
Quadriceps inhibition is a problem that may occur when the knee is very painful, and a reflex inhibits the muscle from contracting.
- Quadriceps lag search for term
-
A 'quadriceps lag' is present when a patient cannot fully 'actively' extend the knee (straighten the leg using muscle contraction), but it can be fully 'passively' extended by the clinician.

- Quadriceps tendinitis search for term
-
Quadriceps tendinitis is an overuse disorder of the quadriceps tendon.
- Quadriceps tendinopathy search for term
-
An overuse condition, where the attachment of the quadriceps (quads) tendon to the upper pole of the patella (kneecap) becomes painful.
- Quadriceps tendon search for term
-

- Quads search for term
-
