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. The PC knot satisfies these criteria and offers variable loop tensioning that allows for improved slidability and initial loop security.
