Fibular head is the rounded, upper end of the fibula bone on the outside of the lower leg. It sits just below the outer side of the knee, near the top of the shin (tibia). Clinicians use it as an important landmark during knee exams, imaging review, and some surgeries. It matters because key ligaments, tendons, and a major nerve are close to it.

Tibial plateau is the top, flat portion of the tibia (shinbone) that forms the lower half of the knee joint. It is where the femur (thighbone) meets the tibia to create the main weight-bearing part of the knee. Clinicians use the term when describing knee anatomy, arthritis changes, and injuries such as tibial plateau fractures. It is also referenced in imaging reports, surgical planning, and rehabilitation discussions.

The Proximal tibia is the upper part of the shinbone near the knee joint. It forms the lower half of the main knee “hinge” where the femur meets the tibia. Clinicians use the term when describing knee anatomy, injuries, arthritis, and surgery. It is a key landmark on X-rays, CT scans, and MRI of the knee.

Distal femur means the lower end of the thigh bone near the knee. It forms the upper half of the knee joint and helps the knee bend, straighten, and carry weight. Clinicians use the term in exams, imaging reports, and surgical planning around knee problems. It is commonly discussed in fractures, arthritis, alignment issues, and knee replacement care.

The Fibula is the smaller bone on the outside of the lower leg. It runs alongside the tibia (shinbone) from just below the knee to the ankle. It helps form important joints and provides attachment points for key muscles and ligaments. In orthopedics, it is commonly discussed in ankle injuries, lower-leg fractures, and lateral (outer) knee pain.

The Tibia is the larger of the two bones in the lower leg and is commonly called the shinbone. It forms the lower half of the knee joint and the upper portion of the ankle joint. The Tibia carries most of the body’s weight as it travels from the femur to the foot. In orthopedics and sports medicine, it is frequently discussed in knee pain, fractures, arthritis, and alignment problems.

The Femur is the thigh bone and the longest bone in the body. It connects the hip to the knee and helps carry body weight during standing and walking. Clinicians discuss the Femur often in knee pain, hip pain, fractures, and alignment problems. It is also a key reference point in imaging and orthopedic surgery planning.

The Patella is the kneecap, a small bone at the front of the knee. It sits within the quadriceps tendon and glides in a groove on the femur. It helps the knee straighten and protects the front of the joint. Clinicians commonly evaluate it in knee pain, kneecap instability, and arthritis.

The Lateral compartment knee is the outer (outside) section of the knee joint. It is where the femur (thigh bone) meets the tibia (shin bone) on the lateral side. Clinicians use the term to describe anatomy, injury patterns, and arthritis location. It is commonly referenced in exams, X-rays, MRI reports, and surgical planning.

Medial compartment knee refers to the inner (medial) side of the main knee joint where the femur meets the tibia. It is a common location for arthritis-related wear, meniscus injuries, and joint-line pain. Clinicians use the term to describe anatomy, symptoms, imaging findings, and compartment-specific treatments. Patients often hear it when discussing “inner knee pain” or “medial” knee osteoarthritis.
