Level I RCT comparing alpha-BSM calcium phosphate cement versus autogenous iliac crest bone graft for filling subarticular defects in unstable tibial plateau fractures (Schatzker I–VI). Enrolling 120 fractures across 12 North American centers, the study asks whether an off-the-shelf bone substitute can match — or beat — the traditional gold standard in preventing articular collapse.
When filling a subarticular void after tibial plateau ORIF, calcium phosphate cement prevents articular subsidence better than iliac crest autograft while eliminating donor-site morbidity — the critical window for collapse is 3–6 months postoperatively, exactly when autograft is resorbing before full incorporation.
