| knee-deep | 1. Rising to the knees; knee-high; as, water or snow knee-deep. "Grass knee-deep within a month." (Milton) 2. Sunk to the knees; as, men knee-deep in water. "Where knee-deep the trees were standing." (Longfellow) Source: Websters Dictionary (01 Mar 1998) |

| knee-elbow position | A prone position resting on the knees and elbows, assumed for gynecologic or rectal examination or operation. Synonym: genucubital position. (05 Mar 2000) |
| knee injuries | Injuries to the knee or the knee joint. (12 Dec 1998) |
| knee jerk | The reflex tested by tapping just below the bent knee on the patellar tendon to cause the quadriceps muscle to contract and bring the lower leg forward. It has given rise to the saying: a knee-jerk reaction. Also known medically as the patellar reflex. (12 Dec 1998) |
| knee-jerk reflex | A sudden contraction of the anterior muscles of the thigh, caused by a smart tap on the patellar tendon while the leg hangs loosely at a right angle with the thigh. Synonym: knee jerk, knee phenomenon, knee reflex, knee-jerk reflex, patellar tendon reflex, quadriceps reflex. (05 Mar 2000) |
| knee joint | A compound condylar synovial joint consisting of the joint between the condyles of the femur and the condyles of the tibia, articular menisci (semilunar cartilages) being interposed, and the articulation between femur and patella. Synonym: articulatio genus. (05 Mar 2000) |
| knee prosthesis | Replacement for a knee joint. (12 Dec 1998) |
| knee reflex | A sudden contraction of the anterior muscles of the thigh, caused by a smart tap on the patellar tendon while the leg hangs loosely at a right angle with the thigh. Synonym: knee jerk, knee phenomenon, knee reflex, knee-jerk reflex, patellar tendon reflex, quadriceps reflex. (05 Mar 2000) |
| knee sprain | <orthopaedics> Any injury to one of six different ligaments which stabilise the knee joint. Those ligaments include: medial and lateral collaterals, medial and lateral meniscus and the anterior and posterior cruciate ligaments. Knee sprains are characterised by knee pain, swelling and tenderness with range of motion. Severe sprains may result in a knee joint effusion (blood inside the joint). Completely torn ligaments may require surgical repair to reestablish knee joint stability. (17 Dec 1997) |
| knock-knee | <medicine> A condition in which the knees are bent in so as to touch each other in walking; inknee. Source: Websters Dictionary (01 Mar 1998) |
| lateral ligament of knee | <anatomy> The cordlike ligament that passes from the lateral epicondyle of the femur to the head of the fibula. Synonym: ligamentum collaterale fibulare, lateral ligament of knee, Winslow's ligament. (05 Mar 2000) |
| locked knee | A condition in which the knee lacks full extension and flexion because of internal derangement, usually the result of a torn medial meniscus. (05 Mar 2000) |
| adhesion phenomenon | A phenomenon manifested by the adherence of antigen-antibody-complement complex to "indicator cells" (microorganisms, platelets, leukocytes, or erythrocytes), the reaction being sensitive and specific for the antigen and antibody in the complex. Synonym: erythrocyte adherence phenomenon, immune adherence phenomenon, red cell adherence phenomenon. (05 Mar 2000) |
| AFORMED phenomenon | As induced pulsus alternans progresses, a state in which alternating heart depolarisations fail to eject any blood, thus allowing longer diastolic filling; the subsequent beat is then able to produce a significant ejection; at high rates the cardiac minute volume and blood pressure may appear normal. Origin: Alternating, failure of response, mechanical, to electrical depolarisation (05 Mar 2000) |
| all-or-nothing phenomenon | <physiology> Refers to the phenomenon where the strength of a nerve impulse is not dependent on the strength of the stimulus. Instead, there is a threshold level of stimulus strength that must be reached before the nerve will fire an impulse (at full capacity). Below the threshold, the nerve will not fire at all. <cardiology> It also refers to the same phenomenon observed in the heart muscle, which will either contract fully or not at all. <psychology> In studies of behaviour, it refers to the same phenomenon where a behavioural stimulus will either produce a complete response or no response at all. Also called all-or-nothing principle, all-or-none law, all-or-none responsiveness, etc. (15 Nov 1997) |
