Prospective pilot study of 26 patients evaluating injectable calcium phosphate cement (Norian SRS) as a bone void filler for subchondral defects in OTA B2–B3 and C3 tibial plateau fractures, with mean 19.7-month follow-up using Lysholm, Tegner, and Rasmussen scoring.
When managing depressed tibial plateau fractures (OTA B2–B3, C3) with significant subchondral void after fragment elevation, injectable calcium phosphate cement is a viable alternative to autograft — it provides immediate structural support allowing earlier weight bearing and avoids donor-site morbidity, though cement extrusion into the joint is a technique-dependent risk that requires careful sequential injection starting at the subchondral surface.
