A double-blind, randomized trial showed a similar significant improvement in pain and function with both, and in active patients the results suggest that PRP may be more beneficial. In the setting of total knee arthroplasty, cementless fixation was shown to be noninferior to cemented fixation at 2 years for functional outcomes in a single-center experience, while there was a small but significant improvement in clinical outcomes with cemented fixation.\u003C\/p\u003E\n\u003Cp id=\u0022p-6\u0022\u003EThe selected update articles include reviews of new trends in foot and ankle surgery, hot topics and controversies in primary total hip arthroplasty, and advances in the treatment of complex knee injuries.
