  5. Specific Issues in Hip Surgery for Younger Patients • “Minimally Invasive Surgery” • Resurfacing Operations • Bearing Surfaces

  6. M.I.S. Surgery • Marketing rather than a scientific term • Effort to perform joint surgery through smaller incisions • Goal of speeding patient recovery

  7. Proceed with Caution • You’re in this for the 20 year rather than the 20 day outcome • Very subtle differences in artificial hip and knee alignment have a big impact in how long they last • Scientific studies of MIS surgery have shown less predictable alignment than standard surgery • Equal or greater damage to underlying muscles • Computer assistance may erase this difference
