Diagnosis and Treatment of Schatzker Type II Tibial Plateau Fracture with An Isolated Bone Fragment: A Case Report and Literature Review

Background An isolated bone fragment from the posterolateral tibial plateau retrieved from the patellofemoral compartment is a rarely seen Schatzker type II tibial plateau fracture and is prone to misdiagnosis. To the best of our knowledge, this injury mechanism has not been previously described. Case presentation A 63-year-old female sustained left knee pain and activity limitation after falling off an electric bicycle. Local hospital ignored the intra-articular bone fragment and failed to provide effective treatment. This case described an uncommon Schatzker type II tibial plateau fracture with an isolated bone fragment, its physical examination and radiological findings, the potential injury mechanism, and surgical protocol. Conclusions Combining the physical examination and radiological findings to evaluate the potential injury mechanism is important for developing an appropriate surgical protocol.
