The potential disadvantages of hip resurfacing are femoral neck fractures (rate of 0–4%), aseptic loosening, and metal wear. Due to the retention of the person's complete femoral neck other advantages exist: Surgeon induced discrepancies in leg length (as could happen with THR) are now minimized. Also, the toe-in or toe-out faults that could occur interoperatively with THR are now over because the femoral neck that determines foot direction is left undisturbed with hip resurfacing.
Hip resurfacing has several potential drawbacks: femoral neck fractures (0–4% rate), aseptic loosening, and metal wear. However, this procedure also provides other benefits: Surgeon-induced leg length discrepancies common in THR are now avoided. Furthermore, the toe-in or toe-out issues that can occur with THR are no longer present since the femoral neck that controls foot direction remains intact.
