Questions about bending over after Hip replacement. I just read in another thread a reminder of not bending over for 6 weeks after surgery. It has prompted this question. I guess I should ask the PT, but I'd also like input from folks who have been there. First, let me tell you about my job.
Hip flexor strain - aftercare. The hip flexors are a group of muscles that help you move, or flex, your leg and knee up towards your body. A hip flexor strain occurs when one or more of the hip flexor muscles becomes stretched or torn. Hip flexors allow you to bend your knee and flex your hip. Sudden movements, such as sprinting, kicking, and changing direction while running or moving, can stretch and tear the hip flexors. Runners, people who do martial arts, and football, soccer, and hockey players are more likely to have this type of injury.
