A small stab through the peroneal sheath at the distal most aspect of the fibula allows quick examination and protection of the peroneal tendons. If excessive, often discolored fluid is present or the integrity of the tendon is poor or tears are present, carry the incision proximally. Full visualization of the tendons is warranted.
Bluntly delineate the extensor retinaculum anteriorly and inferiorly, and tag it for later incorporation into the repair. Introduce a curved hemostat from the distal aspect of the fibula coursing parallel to the anterior border. This protects the peroneal tendons as well as the lateral talar cartilage as one transects the capsule and anterior talofibular ligament. Be sure to leave a cusp of tissue on the distal anterior aspect of the fibula. One should excise the impinging tissue in the lateral gutter or synovitis.
In addition, surgeons can drill visible lateral shoulder talar osteochondral defects and remove loose bodies. If the cusp of tissue is loose, usually from the presence of a loose body, one can reattach the tissue with an anchor in the area of the anterior talofibular ligament insertion onto the fibula.
Move the stack of towels to the forefoot to allow dorsiflexion and eversion of the foot. Employ multiple pants-over-vest sutures utilizing the residual anterior talofibular ligament and associated capsule. Throw all the sutures at once and then individually tie and tension them. Reef the extensor retinaculum up onto the cusp of tissue on the distal anterior aspect of the fibula. Close the subcutaneous tissue and skin in standard fashion. Place a posterior splint with the foot dorsiflexed and everted to support the repair.
When one performs this procedure in isolation, it is typically complete in less than 30 minutes with no assistance necessary.
It is to the surgeon’s benefit to remain as efficient as possible. Simple, often overlooked intraoperative maneuvers can facilitate ease of the procedure. Techniques such as foot position and choice of anesthetic administration during the case make the procedure flow smoother. A surgeon can gain “style” points for accomplishing procedures in a timely and effective manner when other surgeons may struggle.
