[Hip dysplasia].

Hip dysplasia and femoroacetabular impingement are frequent causes of hip pain and can often be treated with joint preserving surgery to prevent secondary osteoarthritis (OA). Patient education, progressive resistance training and weight loss at a BMI > 27 kg/m(2) has documented effect on pain and function in primary hip OA. If wound infection occurs after total hip arthroplasty the patient should not be treated with peroral antibiotics but instead be referred to an orthopaedic surgeon. There is no documentation that post-operative movement restrictions prevent dislocation of hip after total hip arthroplasty.
