Patellar tracking problems in athletes.

Problems of the patellofemoral joint have long been recognized as a source of knee dysfunction. They range in spectrum from pain alone to recurrent instability, yet all are related in origin by congenital predisposition. Problems of the extensor mechanism are prevalent in any and all populations. Most patellofemoral problems respond readily to conservative rehabilitation efforts. Because of its chronic, recurrent nature, satisfactory results remain elusive in some syndromes. In our practice, the newer McConnell techniques have proved to be a positive addition to the extensor mechanism armamentarium, allowing pain-free return to function for most patients.
