Imagine that after years of painful knee symptoms, you have a total knee replacement (TKR). Ahhh, relief at last! But within a couple of months, the knee starts making a loud "clunk" every time you straighten it from a fully bent position. The problem could be the patellar clunk syndrome. This syndrome occurs when a fibrous nodule develops on the back of the kneecap (patella). When the knee bends, this fibrous bump gets trapped within a notch in the surface of the thighbone (femur). (The bottom of the femur meets the top of the tibia in the lower leg to form the knee joint.) As the knee straightens, the bump moves out of the notch. Knee pain and a "crunching" sound occur as the patella moves against the femur. At the same time, a "clunk" is usually heard. Doctors think that two factors cause the patellar clunk syndrome: the design of the joint implant (on the femoral side) and the patient's knee-flexion angle. Generally, only patients with more than average knee flexion get this proble...
Osteoarthritis (OA) is by far the most common joint disorder in the United States and throughout the world. It is a leading cause of pain and disability in the elderly, mostly because of its predilection for the weight-bearing joints. And so today I will talk about osteoarthritis in an important weight-bearing joint: the knee. Overweight people are at greater risk of developing knee OA . In addition, major knee injuries such as ligament or meniscal tears are common causes of knee OA. Ultimately, whether it is the extra force on the knee due to obesity or the disruption of the normal internal components of the knee due to a meniscal or ligament tear, OA is caused by a change in the synthesis and degradation of cartilage and adjacent bone. This in turn results in loss of cartilage and damage to bone, manifested in the patient by pain, swelling, and limited range of motion of the knee . The American College of Rheumatology (ACR) suggests initially treating knee OA...
I'm 15, and for the last 3/4 days I have been having stabbing like pains on the right side of my head, mainly when I first wake up or stand up! I am a worrier and tend to think of extreme things and make myself worried even more, I am going to the doctors tomorrow but I am afraid they will just give me pain killers. Leigh.
We hope your doctor was able to explain the pains and help you. Before prescribing medications, doctors should diagnose what the pains are if at all possible. You don't mention how long these pains last. If they're only seconds long, they might be ice pick headaches. You can find more information in Ice Pick Headaches - The Basics .
If your doctor isn’t able to help you, it may well be time to consult a Migraine and headache specialist. It’s important to note that neurologists aren’t necessarily Migraine and headache specialists
