Everyone who goes into surgery for a total knee replacement (TKR) knows the leg is weak from pain and disuse. When and how does muscle strength come back after the operation? Studies show that many patients have weakness and loss of function that can go on for years. Electrical stimulation of the muscles improves strength in young adults. What effect will it have on older adults after a TKR? Physical therapists enrolled patients who were having both knees replaced at the same time in a study of electrical stimulation. Having subjects with both knees replaced gave researchers a chance to use electrical stimulation on only one side. Results were then compared to the patients' own knee that did not get electrical stimulation. Two groups were formed in this study. One group received the same exercises for both legs. The other group received neuromuscular electrical stimulation (NMES). The NMES group did exercise on one side and exercise along with NMES on the weaker leg. Everyone started th...

An "enigma" is something that's hard to understand, something puzzling. Thigh pain after a surgery for a new hip joint is one of such puzzle. This enigmatic pain can occur when a cementless implant is used. Doctors report several possible causes. Sometimes the implant is too stiff for the bone. It doesn't "bend" enough so that stress builds up between the bone and the implant. The shape and size of the implant are also important. There is a greater chance of thigh pain with a larger implant. The quality of the patient's bone is also important. Poor bone structure from osteoporosis results in a "less stiff" bone. The zone between the implant and weaker bone may be mismatched. Thigh pain can be the result. This pain is usually described as a dull ache. There is no fever and no history of trauma or illness. The patient often points to the spot where the tip of the implant is located. Some patients report only mild discomfort. Others walk with a limp and need to use a cane or walker. The p...
