Straight leg raises help strengthen the hip joint. Perform as follows:

• 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.
