Total knee arthroplasty (TKA) has been around for decades and serves as a very successful procedure to alleviate pain and restore function in a knee with advanced degenerative joint disease. Over the years, there have been many advancements in surgical technique and even more so in implant design. One such technological breakthrough in TKA is the use of robotic-arm assistance for enhanced preoperative planning and intraoperative guidance with dynamic joint balancing and bone preparation.

In this video article, Dr. Zarin demonstrates the operative technique he uses in performing a posterior stabilizing TKA in a varus deformity degenerative knee using Mako robotic-arm assistance.

Open Reduction and Internal Fixation of a Trimalleolar Ankle Fracture

The goal of ankle fracture management is to restore a stable and congruent joint. Operative management is recommended for most displaced fractures, fractures with dislocations, and open fractures.

This video article walks through the surgical management of a 23-year-old male who sustained a trimalleolar ankle fracture with concomitant dislocation and syndesmotic injury following a motor vehicle collision. Dr. Weaver discusses the surgical landmarks and approaches to the ankle, the methods of fixing the malleoli and the syndesmosis, and common concerns that arise during the surgical management of ankle fractures.

Subtalar arthrodesis is currently the mainstay treatment option for the management of recalcitrant subtalar arthrosis.

The patient in this case is a 45-year-old male who developed post-traumatic arthritis of the subtalar joint 14 years following a work-related injury in which he sustained a comminuted, joint-depression type calcaneal fracture after a 10-foot fall from a ladder. Seven years after the initial injury, imaging prompted by progressive hindfoot pain during weight-bearing or following activity revealed progressive degeneration of the subtalar joint, for which he was treated with orthoses, corticosteroid injections, and arthroscopic debridement. After exhausting both conservative and minimally invasive treatment measures at 14 years post-injury, he finally elected to undergo subtalar arthrodesis.

This video article details the methods and techniques involved in subtalar arthrodesis. After an Ollier approach was used to expose the subtalar joint, the arthritic cartilage was removed and the subchondral plate was perforated. Finally, an autogenous bone graft was harvested from the proximal tibia and inserted into the joint space, and compression was achieved by two lag screws.

Cubital tunnel syndrome is a condition that affects the ulnar nerve as it crosses the medial elbow through the retrocondylar groove. It is the second most common compressive neuropathy, causing tingling and numbness in the ring and small fingers. In advanced cases of symptomatic cubital tunnel syndrome, weakness, altered dexterity, and atrophy of the intrinsic muscles of the hand may develop. Cubital tunnel syndrome can be treated with either a cubital tunnel release or an ulnar transposition. In this case, the former is demonstrated on a cadaveric arm using the mini-open technique.

Carpal tunnel syndrome (CTS) is the most common peripheral compression neuropathy and results in symptoms of numbness and paresthesia in the thumb, index finger, middle finger, and half of the ring finger. When CTS symptoms progress and can no longer be managed with nonoperative measures, carpal tunnel release (CTR) surgery is indicated.

In this case, Dr. Asif Ilyas at the Rothman Institute performs CTR surgery on a cadaveric arm via the mini-open CTR technique. A 2-cm longitudinal incision was placed directly over the carpal tunnel, the transverse carpal ligament was exposed and then released, and the wound was closed. Patients are typically sent home with instructions to use their hand immediately postoperatively, while avoiding strenuous use until the incision has healed. Splinting and therapy are not required postoperatively.

In another trauma case with UChicago Medicine, Drs. Kent, Jeffries, Straszewski, and Wilson evaluate and treat a patient with a gunshot wound and femoral fracture. An ABI was obtained, CT angiography was evaluated, and proximal tibial traction was performed for pain management.
