Tibia is the major part of the lower leg and the femur is the upper thigh bone, both together form the knee joint. Yes, the Tibiofemoral joint is the medical term for the knee joint and the Tibiofemoral dislocation in common terms is the knee joint dislocation.
The knee joint is the strongest joint in the human body and it takes reasonably high-energy collision to dislocate this robust joint. As this joint is comprised of multiple ligaments, nerves and arteries, the injury that causes the dislocation tends to damage these cascading problems for the victims. “Knee dislocation is a rare yet serious injury that could be extremely complex to treat due to the increased risk of multiple injuries. The treatment can also vary in type and time based on causes and symptoms of the Tibiofemoral dislocation”, says Dr Niraj Vora, a specialist in knee replacement surgery in Mumbai. So what are the causes and symptoms of Tibiofemoral dislocation and how is it treated, read on to know answers from knee replacement specialist Dr Niraj Vora here:
Tibiofemoral Dislocation Causes:
Knee dislocation is usually caused by hard and direct impact to the knee in high-velocity incidents like car accidents or injury due to hard falls or contact sports. Knee dislocations can happen in two ways based on the side from which the knee got dislocated:
Anterior dislocation: This type of dislocation happens when the knee hyperextends beyond the usual range (>30 degrees).
Posterior dislocation: This dislocation happens a high-energy impact (car accident or hard falls) strikes the knee at the front of the knee and pushes the shin bone or tibia out of its place.
So do these knee dislocations differ in symptoms too? Let’s find out:
Tibiofemoral Dislocation Symptoms:
Both types of knee dislocation show up same symptoms that may be sometimes tough to identify even for seasoned knee replacement specialists. Some of the common symptoms of knee dislocation include:
- Knee pain, swelling and bruising
- Limited ability of the knee
- Visible knee deformity
- Knee losing its ability to bend or bear weight
- Shallow indentation at the back of the knee (happens popliteal arterial injury)
Diagnosis of Knee Dislocation:
Even a minor sign in the above list, after involvement in a high-energy event, must be consulted with a knee specialist as soon as possible. After performing a physical exam, the knee specialist looks at the signs and symptoms of knee dislocation, mobility and function issues and the n orders imaging studies to diagnose the presence and severity of the knee dislocation. The treatment plan is prepared based on the type, cause, medical history and severity of the knee dislocation.
Treatment for Knee Dislocation in Mumbai:
Tibiofemoral dislocations in the majority of cases, involve damage to ligaments, tendons, arteries and blood vessels and hence will need surgery. “However surgery is not readily recommended. A knee replacement specialist usually waits up to 3 weeks after the injury to allow the swelling to subside by using medications, and RICE techniques”, says the best knee replacement surgeon in Mumbai, Dr Niraj Vora.
The knee surgery for knee joint dislocation depends upon the damage to the knee during the cause of dislocation. Closed Reduction, vascular repair and fasciotomy, and ligament reconstruction are some of the common procedures involved in knee joint dislocation. Knee surgery is performed at the right time to fix the dislocation and rehabilitation therapy is performed along with physical therapy. Knee braces, pain medication and crutches are recommended during physical activity to ensure proper mechanics and recovery.
