Strength & Flexibility
Exercises are designed to strengthen the muscles that support the knee to reduce the stress on the knee joint. Muscles strengthened must be stretched to restore range of motion and prevent injury. Gently stretching and strengthening exercises help reduce muscle soreness and keep your muscle long and flexible.

Muscles targeted in the knee conditioning program include:

Quadriceps (font thigh)
Hamstrings (back thigh)
Abductors (inner thigh)
Gluteus Medius and Gluteus Maximus (buttocks)

Length of program
The knee conditioning program typically continues for four (4) to six (6) weeks, unless specified by the doctor or physical therapist. Upon recovery, exercises can continue as a maintenance program for good health. Exercises are performed two (2) to three (3) days a week to restore strength and range of motion to the knees.

Let’s get started
Before every an exercise program, a five (5) to ten (10) minute warm-up helps get the heart pumping and limbers up your muscles (light walk or cycle on the stationary bike). Following the warm-up and after completing the exercise program, stretch out all the muscles.

Never ignore what the body tells us
Any pain experienced during physical exercise should not be ignored, consult the doctor or physical therapist to rule out any serious consequences to continuing the exercise program.
