Randomized Controlled Trial Comparative StudyBiomechanical comparison of three techniques for fixation of tibial avulsion fractures of the anterior cruciate ligament.
To evaluate the initial stability of a suture anchor fixation and to compare this with a screw fixation and pull-out suture fixation for anterior cruciate ligament tibial avulsion fracture. ⋯ These biomechanical results suggest that the initial fixation strength of suture anchor fixation was not less than that of screw fixation or pull-out suture fixation. And, the initial displacement of suture anchor fixation was lower than that of screw fixation or pull-out suture fixation. The suture anchor fixation appears to be a good alternative fixation technique for repair of anterior cruciate ligament tibial avulsion fracture.

MRI but not arthroscopy accurately diagnoses femoral MPFL injury in first-time patellar dislocations.
The purpose of this study was to investigate whether the femoral part of the medial patellofemoral ligament (MPFL) and its injury can be accurately assessed by standard knee arthroscopy in first-time patellar dislocations or whether preoperative MRI is required to determine injury location in patients where primary MPFL repair is attempted. ⋯ Diagnostic study of non-consecutive patients, Level III.

Case ReportsDisplaced osteochondral fracture of the lateral femoral condyle associated with an acute anterior cruciate ligament avulsion fracture: a corollary of "the lateral femoral notch sign".
Anterior cruciate ligament (ACL) rupture is usually accompanied by bone contusions resulting from impact of tibia on femur. The injury sometimes becomes manifest as a depression on the lateral femoral condyle giving rise to "lateral femoral notch" sign. The authors describe a rare case of impaction of the tibia and femur resulting in an osteochondral fracture rather than the usual bone contusion, which frequently occurs with ACL rupture. Open reduction and internal fixation of both the ACL avulsion fracture and the osteochondral fracture from the lateral femoral condyle were done, and the patient had a good outcome at 1-year follow-up. Level of evidence V.
