Posterolateral corner (PLC) knee injuries require careful evaluation. Complete PLC tears often need surgery for healing, as non-operative treatments are rarely successful.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Knee Biomechanics
Background:
- Posterolateral corner (PLC) injuries are a significant component of overall knee ligament damage.
- These injuries can be occult, necessitating a high index of suspicion during knee injury assessments.
Purpose of the Study:
- To provide a comprehensive review of posterolateral corner (PLC) injuries.
- To cover anatomy, biomechanics, diagnostic algorithms, and treatment/rehabilitation protocols for PLC injuries.
Main Methods:
- Review of existing literature on PLC injuries.
- Discussion of diagnostic techniques including physical examination and stress radiography.
- Analysis of non-operative and operative treatment strategies.
Main Results:
- Complete PLC lesions have a poor prognosis with non-operative management.
- Surgical intervention is frequently required for complete PLC injuries.
- Stress radiography aids in objectively assessing the extent of PLC lesions.
Conclusions:
- Accurate diagnosis of PLC injuries relies on clinical suspicion, thorough examination, and advanced imaging.
- Treatment decisions for PLC injuries depend on injury severity.
- Surgical treatment is often indicated for complete PLC tears to ensure adequate healing and functional recovery.

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...
