Minimally Invasive Anteromedial-assisted Reduction and Subchondral Rafting Fixation for an Isolated Posterolateral Tibial Plateau Fracture: A Novel Technique
摘要
Isolated posterolateral tibial plateau fractures present significant surgical challenges due to complex regional anatomy and limited surgical access.
MethodsWe present a new minimally invasive anteromedial-assisted technique for treating depressed posterolateral tibial plateau fractures. A guided K-wire and bone punch are used to elevate the articular fragment indirectly. After reduction, a pre-bent 2.4 mm T-plate is slid subchondrally to support the reduced segment. Intraoperative arthroscopy is used to confirm anatomic reduction.
ResultsIntraoperative arthroscopy and postoperative CT scans confirmed anatomic reduction and stable implant placement. The patient regained full, pain-free knee motion by the 12-week follow-up.
ConclusionThis technique effectively restores joint congruence by combining internal subchondral support with arthroscopic confirmation. It offers a practical approach that avoids the need for extensive soft-tissue dissection typically associated with posterior approaches.
