Pearls and Pitfalls of Surgical Technique

Pearls	Pitfalls
• A true lateral of the knee does not always represent the most prominent aspect of the proximal trochlea • Use a knife to mark the cartilage arthroscopically at the edge of the planned resection • Check tracking of the patella and its transition before and after resection • There may be cartilage covering the bump; this should not preclude resection	• Do not remove the bump and create a vertical step off; taper the transition point • Do not rely on your eyes arthroscopically; confirm resection location on fluoroscopy • Resecting from a standard anterior arthroscopy portal will result in under-resection; use an accessory portal • Viewing from the standard arthroscopy portals will not allow for full visualization of the bump; use the proximal accessory portal to visualize before/during/after resection
