[Intragenicular subchondral fracture. Report of 10 cases]

10 cases of subchondral fracture of femoral condyle or tibial plateau with or without rupture of lateral meniscus were reported. All these fractures were compressive type and were treated by open poking reduction and filling of the remaining defect with cancellous bone. Follow-up for 5 to 9 years of the 10 patients showed that they regained painless stable knee and resumed their previous works. We purposely reviewed genicular radiograms of 100 cases who had knee joint injuries, and found that certain number of them showed depression on articular surfaces of femoral condyles, possibly compressive fractures, which should have been considered more seriously. The essential points of diagnosis and the operative keys of surgery for this kind of injury have been mentioned in the paper.
