Summary
Rectus femoris fibrosis from injections caused stiff-knee gait. Surgical intervention improved mobility, highlighting the need to avoid intramuscular injections in this area to prevent gait dysfunction.
Area of Science:
- Orthopedics
- Biomechanics
- Rehabilitation
Background:
- Rectus femoris fibrosis can lead to significant gait abnormalities, specifically stiff-knee gait.
- Intramuscular injections into the quadriceps are a potential cause of rectus femoris fibrosis.
Observation:
- A female patient presented with stiff-knee gait attributed to rectus femoris fibrosis post-multiple quadriceps injections.
- Instrumented three-dimensional gait analysis was employed for treatment planning and outcome assessment.
Findings:
- Surgical intervention resulted in notable improvements one year post-operation.
- Gait parameters enhanced, including walking speed, step length, anterior pelvic tilt, and swing phase knee flexion and ankle dorsiflexion.
Implications:
- Instrumented three-dimensional gait analysis is valuable for diagnosing gait impairments and monitoring surgical outcomes.
- Avoiding intramuscular injections into the rectus femoris muscle is crucial for preventing stiff-knee gait and related disability.

01:16Bones of the Lower Limb: Femur and Patella
8.1K
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...

01:23Muscles that Move the Leg
6.8K
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...
