Having an operation is a big decision. When deciding to recommend surgery, Dr. Marx treats all patients’ cases individually and suggests surgical options only when appropriate. Dr. Marx does many complex and revision operations, so many of the patients he sees have had several opinions prior to seeing him. He also sees many patients who have been told they need a more routine operation and would like to be in the capable and caring hands of Dr. Marx. Read below for further information to help find the right procedure for you.
Anterior cruciate ligament (ACL) injuries are one of the more common sports-related injuries. Using arthroscopic techniques, Dr. Marx specializes in reconstructing the ACL. Dr. Marx utilizes a variety of techniques and graft sources depending on the patient’s case, including patellar tendon, hamstrings, and transplant. Dr. Marx is also experienced in revision surgeries after failed ACL reconstruction.
In some cases, more than one ligament in the knee (i.e. ACL, PCL, MCL, and/or LCL/posterolateral corner) requires reconstructive and/or revision surgery for failed ACL reconstruction. Dr. Marx is also experienced in these complex surgeries, having published and lectured extensively on this topic at national and international conferences.
Dr. Marx has experience performing shoulder stabilization surgeries for patients following dislocations or fractures after trauma. He also offers revision surgeries for patients who have had failed dislocation repairs.
Dr. Marx offers arthroscopic rotator cuff repair surgery for small and large tears. The arthroscopic approach involves four small incisions, each measuring less than a centimeter, and can relieve pain and improve strength in injured shoulders.
Dr. Marx performs many other complex knee surgeries. Patients with meniscus injuries may come in for a consultation for meniscus surgery or meniscus transplantation. During these surgeries, Dr. Marx repairs or removes torn sections of the meniscus arthroscopically. He also performs osteotomies to improve leg alignments, cartilage transplants, and complex knee-revision surgery.
Patients with pain and limited movement that prevent normal function and impact quality of life often find relief with shoulder or knee replacements. Joint replacement surgery can allow patients who are limited by their arthritis to return to a more active and normal lifestyle.
Dr. Marx has special expertise in treating knee problems in pediatric and adolescent patients. He performs physeal-sparing ACL reconstruction for skeletally immature (still growing) patients to avoid injury to the growth plates. He also has extensive experience treating discoid meniscus in children as well as Osteochondritis Dissecans (OCD) and performs a variety of techniques to address these lesions.
