Summary
High-energy blasts in combat cause knee ligament injuries, especially in amputees. Early diagnosis and tailored treatment are crucial for restoring an active lifestyle despite complex challenges.
Area of Science:
- Orthopedic surgery
- Trauma surgery
- Military medicine
Background:
- Combat-related high-energy blast events frequently cause musculoskeletal injuries.
- Ligamentous knee injuries in military amputees are often complex and difficult to diagnose.
- These injuries present unique challenges in surgical timing, graft selection, and fixation methods.
Purpose of the Study:
- To highlight the diagnostic and treatment challenges of ligamentous knee injuries in combat amputees.
- To emphasize the importance of recognizing and managing these injuries.
- To discuss the critical role of treatment in patient rehabilitation and return to an active lifestyle.
Main Methods:
- Review of combat-related knee injuries in amputee populations.
- Analysis of diagnostic difficulties due to soft tissue trauma and delayed ambulation.
- Comparison of treatment algorithms for combat versus non-combat multi-ligamentous knee injuries.
Main Results:
- Ligamentous knee injuries in amputees are frequently underdiagnosed.
- Surgical options and rehabilitation strategies are limited by amputation and associated comorbidities like TBI.
- Successful treatment is vital for functional recovery.
Conclusions:
- Recognition and timely management of ligamentous knee injuries in combat amputees are essential.
- Addressing these complex injuries improves the potential for patients to return to an active lifestyle.
- Multidisciplinary approaches are necessary for optimal outcomes.

Bones 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...
Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Muscles 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...
