Summary
This case report details a rare popliteal tendon dislocation in a 48-year-old female, treated successfully with arthroscopic repositioning and radiofrequency. This highlights a novel approach to knee instability.
Area of Science:
- Orthopedic Surgery
- Knee Anatomy
- Sports Medicine
Background:
- The posterolateral corner of the knee is complex, with the popliteal tendon's anatomical variations crucial for knee stability.
- Previous research has highlighted the interconnectedness of the popliteal tendon with surrounding knee structures.
Observation:
- A 48-year-old female presented with knee pain and a sensation of instability following an external rotation injury.
- Clinical examination revealed voluntary pseudoblocking, indicative of a significant knee derangement.
Findings:
- Arthroscopy revealed a dislocated popliteal tendon anterior to the lateral femoral condyle with a longitudinal tear.
- The popliteal tendon was successfully repositioned and stabilized using radiofrequency treatment and a plaster cast.
Implications:
- This case presents a unique instance of popliteal tendon dislocation, a condition not previously well-documented in medical literature.
- The successful arthroscopic management suggests a viable treatment option for this rare knee injury.
- Further research into the biomechanics and treatment of popliteal tendon instability is warranted.

01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.

01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:20Muscles that Move the Thigh
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar fascia...

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
