Patellar tendinitis, also known as jumper's knee, is an overuse injury of the tendon that straightens the knee. [1] Symptoms include pain in the front of the knee. [1] Typically the pain and tenderness is at the lower part of the kneecap, though the upper part may also be affected. [2] Generally there is no pain when the person is at rest. [2]
Prepatellar bursitis is an inflammation of the prepatellar bursa at the front of the knee. It is marked by swelling at the knee, which can be tender to the touch and which generally does not restrict the knee's range of motion. It can be extremely painful and disabling as long as the underlying condition persists.
The painful point can be felt as a nodule or band in the muscle, and a twitch response can be elicited on stimulation of the trigger point. Palpation of the trigger point reproduces the patient's complaint of pain, and the pain radiates in a distribution of the muscle and/or nerve.
Dry needling has its own theoretical concepts, terminology, needling technique and clinical application." [16] The American Academy of Orthopedic Manual Physical Therapists states: Dry needling is a neurophysiological evidence-based treatment technique that requires effective manual assessment of the neuromuscular system.
The major goal of any microneedle design is to penetrate the skin's outermost layer, the stratum corneum (10-15μm). [17] Microneedles are long enough to cross the stratum corneum but not so long that they stimulate nerves which are located deeper in the tissues and therefore cause little to no pain. [13]
Knee pain is more common among people working in the cold than in those in normal temperature. [21] Cold-induced knee pain may also be due to tenosynovitis of the tendons around the knee, in which cold exposure has a specific role, either as a causative or a contributing factor. [21]
Fire needle acupuncture also known as fire needling is an acupuncture technique that involves quickly inserting a red hot needle into acupuncture points on the body. [1] Deep insertions result in greater pain and other side effects. [2] Fire needling combines conventional acupuncture and cauterization with heated needles. [3]
Generally speaking, the muscular pain is steady, aching, and deep. Depending on the case and location the intensity can range from mild discomfort to excruciating and "lightning-like". Knots may be visible or felt beneath the skin. The pain does not resolve on its own, even after typical first-aid self-care such as ice, heat, and rest. [4]
