Ankle sprains are one of the most common sports-related injuries. They affect 10,000 people per day. When the ligaments on the outside of the ankle are stretched or torn, patients can have pain and feelings of instability. If symptoms persist after non-surgical treatment, surgery may be required. The goal of this surgery is to restore normal stability to the ankle. This should also fix your feeling that the ankle “gives way” and any pain that is associated with an unstable ankle.
Treatments
Lateral Ankle Ligament Reconstruction
Lesser Metatarsal Shortening Osteotomy
Each foot has five metatarsals. These are the long bones of the foot. They connect the toes to the rest of the foot. They also make the ball of the foot. The lesser metatarsals are the bones that connect to the second through fifth toes (not the first, or big toe).
An osteotomy is a cut made in the bone. It is similar to breaking the bone but in a very controlled manner. A lesser metatarsal shortening osteotomy changes the pressure distribution under the ball of the foot, relieving pain. It also can be used to put a chronically dislocated toe back in position.
Lisfranc Surgery
The Lisfranc ligament runs between two bones in the middle of the foot called the medial cuneiform and the second metatarsal. The place where these two bones meet is called the Lisfranc joint. The name comes from French surgeon Jacques Lisfranc de St. Martin (1790-1847), who was the first physician to describe injuries to this ligament.
Tearing of the Lisfranc ligament and other ligaments around the Lisfranc joint can lead to instability and disruption of the joints in the middle of the foot. The goal of surgery is to restore normal alignment to the foot. Whether the injury results in a subtle misalignment of the bones or a more obvious dislocation of joints, the surgery is intended to put the bones back into their original position.
Midfoot Fusion
The midfoot is the middle of the foot. It refers to the bones and joints that make up the arch and connect the forefoot (front of the foot including the bones of the toes) to the hindfoot (back of the foot including the ankle bone and the heel bone).
Midfoot fusion is a procedure in which the different bones that make up the arch of the foot are fused together. Fusion eliminates the normal motion that occurs between two bones. Since there is very little movement in the small joints of the midfoot, the function of the foot can be preserved.
Mosaicplasty for Osteochondral Lesions of the Talus
Osteochondral lesions of the talus (OLT) are ankle joint injuries involving damage to the joint surface (cartilage) and/or underlying ankle bone (talus). A normal, healthy ankle joint is made up of smooth cartilage supported by strong bone underneath. Sometimes an ankle injury leads to damaged, rough areas of cartilage and bone underneath. Foot and ankle orthopaedic specialists call this type of injury an OLT. Since the ankle joint moves while walking, the rough spots may cause pain, swelling, stiffness, and decreased motion. It is kind of like having a pothole in the joint surface.
One way to treat the damaged ankle cartilage is through surgery. One type of surgery is called mosaicplasty (MP), which is the transplant of small amounts of bone and cartilage. The primary goal of this procedure is to smooth out the surface of the ankle joint by replacing the unhealthy spots with healthy, smooth cartilage. By reconstructing the surface, pain and other symptoms should decrease or stop all together.
Naviculocuneiform Fusion
The naviculocuneiform (NC) joint is located in the middle of the foot. It consists of four bones: the tarsal navicular and the medial, middle, and lateral cuneiforms.
The main reason to perform NC joint fusion is to relieve pain related to arthritis. Arthritic joints in the midfoot typically occur after trauma to that region or as part of a collapsing foot arch. When a joint is arthritic, the cartilage has worn away and the bony surfaces rub together, which causes pain. The goal of the fusion is to get the bones to heal together so the pain goes away. Sometimes patients whose arches have collapsed will have a deformity that requires NC fusion to correct it.
Orthotics
Orthotics, also called orthoses, are devices that are worn to relieve pain associated with foot and ankle deformities and help prevent or delay surgery. Most people think of shoe inserts or arch supports when they hear the word orthotics, but they can include devices such as foot pads, shoe inserts, ankle braces, and similar items. Treatment often can begin with less expensive off-the-shelf orthotics and progress to custom orthotics if the symptoms and diagnosis require it.
Percutaneous Achilles Tendon Lengthening
Percutaneous Achilles tendon lengthening in a procedure used to stretch a tight Achilles tendon and increase motion at the ankle joint.
Peroneus Longus to Achilles Tendon Transfer
A peroneus longus (PL) to Achilles tendon transfer is done to restore strength across the ankle joint. Strength may have been lost due to an injury to the Achilles tendon or a neurological disorder. Also, patients with Achilles tendon pain that has not improved from non-surgical treatment may benefit from this transfer. Other tendons (such as the tendon to the big toe or lesser toes) may be chosen for the transfer instead of the PL, based on the underlying anatomy and function.
Pilon Fracture Surgery
The tibia (shin bone) and the fibula are the bones of the lower leg. Pilon fractures are injuries that occur at the lower end of the tibia and involve the weightbearing surface of the ankle joint. The fibula also may be broken. These injuries were first described more than 100 years ago and remain one of the most challenging problems for orthopaedic surgeons to treat. Common causes of pilon fractures are falls from a height and car accidents.
The goals of pilon fracture surgery are to restore alignment and stability and allow healing of the tibia and fibula at the ankle joint. Once the fractures are healed, your foot and ankle orthopaedic surgeon's goals are to restore movement and strength at the patient’s ankle.
