Surgical Pearls and Potential Pitfalls of Arthroscopic Extensor Carpi Radialis Brevis Repair

Peasrls

Careful evaluation of the radiocapitellar joint with adequate excision of the hypertrophic plica and restoration of the tension of the lateral ulnar collateral ligament if necessary.

A retractor could be used to improve the visualization of the anterior compartment.

Ensure that adequate ECRB tendon is released to unload the inflammatory tissue.

The direction of the drill bit is angled 45° cephalically in the horizontal plane to minimize the risk of penetration into the joint.

Have the anchor immediately available for insertion and maintain the drill guide position during anchor insertion.

Pitfalls

Avoid injury to the lateral collateral ligament when releasing the ECRB tendon from the lateral epicondyle.

Beware of the radial nerve just anterior to the radial head when the capsule is cleared in the anterior compartment.

Careful suture management to ensure that only the ECRB stump is reattached and ECRL is not involved during knot tying.
