I advise patients not to return to impact sport for 1 year after surgery. For those patients who want to road run, I get them running on a treadmill at 10 months post-op and they resume road running at 12 months post-op. My unit published on activity level after resurfacing some years ago in a group of patients who followed those rules. In young men with a single osteoarthritic hip resurfaced, 92 % played sport and 62 % played impact sport. The ladies were not quite as active, but you can see from the publication that they still had an impressive activity level. In the total group their 10 year implant survival is 99.8 % showing that high activity introduced at a sensible

The computed neck-shaft angle and the size of the femoral component were recorded in 100 consecutive hip resurfacings using imageless computer-navigation and compared with the angle measured before operation and with actual component implanted. The
I have now done about 185 resurfacings for AVN cases over a 5 year period with many patients crossing the 4 yrs mark. It is interesting to note there has not been a collapse or fracture neck of femur even in a single patient.
It is wrong to think that the AVN continues forever in the femoral head. AVN is a one time event in which a strikingly similar sector of necrosis occurs in most femoral heads ( anteo supero lateral part) due to blockage of presumably the same vessel in all patients. This sets off a series of changes which are is marked by sectoral collapse. This is primary collapse of AVN and most patients are likely to develop it. Any kind
Dr. Macaulay You may feel some numbness in the skin around your incision. You also may feel some stiffness, particularly with excessive bending. These differences often diminish with time and most patients find these are minor compared to the pain and limited function they experienced prior to surgery.
Mr. McMinnIf someone is allergic to certain metal jewellery, what are the chances of having a deep tissue allergy? What is the most accurate way of testing someone for a deep tissue allergy? It is estimated that approximately 10% of the population shows skin (cutaneous) allergy to metal products like costume jewellery. In terms of deep tissue allergy the leading authorities agree that, ‘clinically important metal hypersensitivity in patients with metal-on-metal bearings appears to be low’. In our series only 0.3% of patients required a revision for presumed metal debris reaction. It is not clear if these cases represent a true allergic response or an expected response to excess debris. There is no proven way of testing for deep tissue allergy. Cutaneous testing works

From the Joint Center, Schulthess Clinic, Zurich, Switzerland Published on May 1, 2007 Background: No information is available concerning patients’ sports activity after hip resurfacing arthroplasty. Hypothesis: Patients treated by hip resurfacing arthroplasty will be able to achieve a high level of sports activity. Study Design: Case series; Level of evidence, 4. Methods: We surveyed 112 patients by postal questionnaire to determine their sporting activities at a mean of 23.5 (range, 9–40) months after hip resurfacing surgery. Data were also analyzed separately for older and younger patients and women and men, respectively. Results: Of 112 patients, 110 participated in an average of 4.6 sport disciplines after surgery, compared
