- Lay on your back on a flat surface.
- Bend the knee of your uninvolved leg (the one that wasn't operated on) to a 90-degree angle, and keep your foot flat on the surface. Keep your involved leg straight without the knee bent.
- Slowly lift the involved leg six inches off the floor (by contracting the front thigh muscles). Hold for five seconds.
- Slowly lower your leg to the floor. Relax and repeat 10 more times.
The knee of the raised leg should remain straight throughout this exercise. Focus on lifting by using the muscles on the front of your hip joint.
