Which muscle, if injured, will cause a limp besides the tensor fascia lata?

Injury to the psoas major muscle can indeed result in a limp. The psoas major is a key muscle in hip flexion and plays a critical role in stabilizing the pelvis while walking. When this muscle is injured, it can significantly impair the ability to flex the hip and maintain proper gait, leading to compensatory mechanisms such as limping.

The psoas major also contributes to trunk stability and posture. An injury could lead to lateral pelvic tilt or difficulty in lifting the knee, impacting the efficiency of walking and causing a visible limp. This makes it clear that an injury to the psoas major has direct consequences on mobility and gait dynamics.

In contrast, while the other muscles listed also have important roles in hip function and movement, their injury may not necessarily result in a limp as pronounced as what would be seen with a psoas major injury. For instance, the gluteus maximus is primarily involved in hip extension and plays a role in maintaining an upright posture; injury here may affect stride length but does not directly cause a limp in the same way. Similarly, the rectus femoris aids in both hip flexion and knee extension, and while an injury could lead to some difficulties, it would not create
