Anatomy of the knee joint
Osmosis from Elsevier・2 minutes read
The knee joint is a complex structure consisting of multiple articular surfaces, ligaments, and muscles that work together to provide stability and allow for flexion and extension of the lower limb. Various ligaments, including the tibiofemoral ligaments and extra capsular ligaments, along with intraarticular structures like the cruciate ligaments and menisci, play crucial roles in maintaining the knee joint's stability.
Insights
- The knee joint is stabilized by a complex network of ligaments, muscles, and intraarticular structures, emphasizing the critical role they play in maintaining joint integrity and function.
- The knee joint's anatomy comprises distinct articular areas, including femorotibial and femoropatellar articulations, highlighting the intricate design that allows for flexion and extension of the lower limb, underscoring the joint's mechanical versatility and importance in human movement.
