What is the Femorotibial joint?
The femorotibial joint is the main spheroid part of the stifle joint. It is formed by the thick, rollerlike condyles of the femur articulating with the flattened condyles of the tibia. In carnivores, it is freely connected with the lateral and medial sacs of the femoropatellar joint, the other part of the stifle joint.
What are the 4 main ligaments of the knee?
They are:
- Anterior cruciate ligament (ACL). This ligament is in the center of the knee.
- Posterior cruciate ligament (PCL). This ligament is in the back of the knee.
- Medial collateral ligament (MCL). This ligament gives stability to the inner knee.
- Lateral collateral ligament (LCL).
What are the 5 main ligaments of the knee?
The knee has six main ligaments:
- Anterior Cruciate Ligament (ACL) The ACL is located in the center of the knee toward the front.
- Posterior Cruciate Ligament (PCL)
- Medial Collateral Ligament (MCL)
- Lateral Collateral Ligament (LCL)
- Fibular Collateral Ligament (FCL)
- Coronary Ligaments.
What ligament prevents varus forces at the knee?
The fibular or lateral collateral ligament (LCL) is a cord-like band and acts as the primary varus stabilizer of the knee. It is one of 4 critical ligaments involved in stabilizing the knee joint.
How do you heal a torn knee ligament without surgery?
But full ACL tears cannot be healed without surgery. If your activities do not involve making pivoting movements on the knee, physical therapy rehabilitation may be all you need. Special exercises may help train the musculature around the knee to compensate for the torn ACL and stabilize the joint.
What’s the difference between valgus and varus?
Summary. Valgus alignment is known as knock knee syndrome. It shifts the load-bearing axis to the outside of the knee joint, forcing the knees to be positioned inward. Varus alignment, or bow leg syndrome, causes the load-bearing axis of the leg to shift to the inside, pushing the knees outward.
What is a femorotibial prosthesis?
A knee joint femorotibial (uni-compartmental) metal/polymer porous-coated uncemented prosthesis is a device intended to be implanted to replace part of a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surface.
How is the medial femorotibial joint (MFJ) distended?
The medial femorotibial joint may be distended with sterile fluid through an 18-gauge needle inserted cranially, but the authors generally find this unnecessary. A skin incision is made and continued through the fascia between the middle and medial patellar ligament about 2 cm proximal to the tibial crest.
What type of joint is the tibiofemoral?
The tibiofemoral joint is a modified hinge synovial joint between the distal femur and the proximal tibia.
What is the FDA recommendation for the treatment of titanium femoral components?
In the literature, titanium alloy (Ti-6Al-4V) articulating surfaces have been shown to produce metallic particles resulting in an adverse tissue response and high third-body wear. Therefore, for both types of prostheses, FDA recommends that the titanium femoral components have a treated surface (e.g., nitrogen ion).
