Straighten phase

a.

Summary Introduction

To determine: The knee motion during straighten phase.

Introduction: Knee is the largest and complex joint in the body. The knee articulates the femur of the thighbone to the tibia of the shinbone. The collateral ligaments of the knee are present outer to the knee and help to connect upper and lower leg bones to the knee.
