Traumatic hip dislocation in athletes.

Sports injuries are increasingly prevalent. Dislocations of the hip are rare; however, they are seen in high-velocity sports such as football and rugby. The injuries may be described as anterior or posterior, and classified according to severity of injury.

The PC knot: a secure and satisfying arthroscopic slip knot.

In an attempt to attain equivalent results in arthroscopic versus open shoulder and knee soft tissue reconstructions, orthopaedic surgeons require reproducible techniques and quality equipment. A new arthroscopic slip knot is proposed: the PC knot. The optimal arthroscopic slip knot must be (1) low profile, (2) easy to throw, (3) slide well, (4) easy to set, and (5) provide excellent initial security for reliable soft tissue apposition.
