Hip Revision Surgery |
Please enjoy your new hip jointAfter the recovery period (up to nine months) your hip joint should allow the vast majority of normal activities. The muscles will recover to provide strength and endurance, while the scar tissue will soften and allow a good range of movement. Most patients will not notice any functional limitations and about one third of patients will report that they "forget" they have an artificial joint.Limitations to prevent dislocationThe natural hip joint socket (acetabulum) has a cut away to allow extra movement before the neck and rim touch. This allows "extra" movement forwards and across the body. Artificial joints are symmetrical, usually with full hemispherical coverage, and therefore cannot allow a "full" normal range of motion.When the parts of the artificial hip impinge (B) this can cause the hip to lever out of joint - dislocate. Activities likely to cause this complication are at the extremes of normal hip function:
Recurrent dislocation may result from failure of normal muscle tension to hold the joint in place, or impingement during movements inside the normal functional range. More than three dislocations suggests the need for careful assessment and revision surgery. Limitations to prevent early looseningExcessive loading of the hip will increase the risk of early failure. Impact loading is considered to be the most harmful as energy is dissipated in to the implant, its fixation and the supporting bone.Obesity is the commonly cited as a risk factor for early failure, this view is not well supported by research. Most surgeons advise patients to avoid impact loading to protect artificial joints:
