Poor results from the isoelastic total hip replacement: 14-17-year follow-up of 149 cementless prostheses.

abstract：BACKGROUND:By arthroscopy, we observed a phenomenon that, according to our knowledge not previously described, we call the "biceps tendon footprint" (BTF)--an area of chondromalacia beside the bicipital groove. PATIENTS AND METHODS:We studied 118 shoulder arthroscopies prospectively. We documented whether a BTF could ...
