There is some convincing evidence that altered kinematics is a major factor in patellofemoral pain syndrome (PFPS). Kinematics refers to patterns of movement -- specifically how the patellofemoral joint and the knee joint rotate and glide in relation to one another during motion. The patellofemoral joint occurs where the patella (kneecap) glides up and down over the femur (thighbone). Increased pressure from contact between the patella and the femur can lead to PFPS. This is called retropatellar stress -- it means behind the kneecap. Stress on the patellofemoral joint is made worse by rotations of the lower leg during weight-bearing activities. And repetitive actions with weight-bearing load during running and jumping increase retropatellar stress. The result is PFPS. In this study, physical therapists attempt to use a two-dimensional (2-D) method of measuring knee alignment. The measurement was called the frontal plane projection angle (FPPA). The hope was to find a simple tool to use ...
Studies show muscle weakness after total knee replacement (TKR) is common months and even years after the surgery. This study compares the force produced during a single-leg press after TKR. Nine patients with TKR were compared to nine adults without TKR (the control group). This is the first study to measure force produced by the leg after TKR in a weight-bearing position. It's unique because force is examined across several joints using many muscle groups. This gives a better idea of what's going on in a fully weight-bearing position. Other studies have reported on forces in one joint at a time. Often only the knee extensor muscles are tested. The authors report that there is much less force through the leg with the joint replacement. These measures were lower when compared to the patient's healthy leg and when compared to the control group. This shows that the entire leg, not just one set of muscles, has less power. The researchers suggest that the loss of force in the leg with the TK...

Legacy, what will you leave behind? As you can read, the dictionary speaks of money, property, business etc. but I really will have not much of the sort to leave as my legacy. I am donating my body to science, maybe all the suffering I have been through can lessen the load on someone in the future. I have my home, my tools a small amount of life insurance, certainly ...
