Tibial eminence fractures result from both contact and noncontact injuries. Skeletally immature persons are especially at risk. In adults, isolated fractures of the tibial eminence are usually associated with higher-energy mechanisms. The incidence of concomitant intra-articular injuries with tibial eminence fracture is high; MRI is useful in evaluating this injury. Nondisplaced fractures are amenable to nonsurgical management. Displaced fractures are managed with arthroscopic reduction and fixation with either sutures or screws. Although most fractures heal successfully, residual laxity usually persists because of prefracture anterior cruciate ligament midsubstance attenuation. This does not typically manifest in subjective instability, and reconstruction of the anterior cruciate ligament is rarely required. Patient factors, surgeon experience, and fracture pattern must be carefully considered before undertaking surgical repair.
