I am not a military resident, but had the pleasure of roatating with a number at Shock Trauma - yes, even the military sends their residents out for better Level I trauma experience.
My insight would be that military residents are well-trained and capable, but that their exposure to elective Orthopaedics has suffered greatly as a consequence of our international engagements. The number 1 priority of the military medical establishment is the care of returning soldiers, and the prompt return to action of those with "minor" injuries. This is obviously appropriate, but it does mean that the education of Ortho residents is on the back burner.
Military residents report that they are currently inundated with serial washouts of traumatic amputation stumps. They do some interesting reconstructions, and have a relatively good overall trauma experience, although much of it is referral trauma. The also manage to squeeze in a good amount of sports (Can't let meniscal injuries and ACL tears keep the soldiers away from Iraq).
When it comes to joint replacement, however, there is no room on the OR schedule. Patients who need elective surgery are being deferred until there is less of a backlog from war injuries.
This situation may or may not change with time, but I know the military residents looked at the Case Logs of thier civilian colleagues with envy.
These are just my observations. Find military residents. Ask them.
