Table 1

Neuromuscular control exercises program.

1st–3rd daysMobilization: tolerated weight-bearing mobilization with crutches
Exercises:
Quadriceps isometric setting with towel under the heel, straight leg raising (SLR) with full knee extension (with weights at ankle), raising the leg above the ground 40–50 cm in 10 seconds, holding for 10 seconds, and slowly lowering in 40 seconds
Restriction: avoid active terminal knee extension (30° to full extension)

3rd days-3rd weekRange of motion: 0 to 90° flexion
Mobilization: tolerated weight-bearing mobilization w/wo crutches
Exercises:
Quadriceps isometric setting with towel under the heel, SLR with full knee extension (with weights at ankle), raising the leg above the ground 40–50 cm in 10 seconds, holding for 10 seconds, and slowly lowering in 40 seconds, and heel slides (at 0–90° flexion)
Restriction: avoid active terminal knee extension (30° to full extension)

3rd–6th weekRange of motion: 0 to 120° flexion
Mobilization: tolerated to full weight-bearing mobilization with knee brace
Exercises:
Single leg stance, balance reach leg and balance reach arm exercises, lunges (all directions), step-up (all directions) on other side of the patients, and bilateral squat
Restriction: avoid active terminal knee extension (30° to full extension)

6th–12th weekExercises:
Single leg stance, balance reach leg and balance reach arm exercises, lunges (all directions), step-up (all directions), step-down (all directions), one-legged squat, box heel touches (all directions), and single leg pelvic bridge on operated side of the patients, and ball exercises during athletic position

12th–24th weekExercises:
Single leg straight leg dead lift, sumo squat, and weights added to all exercises
Special stair exercises: (stair should be 18 cm in height and 30 cm in depth)
Explanation:
Stair exercise (1): stand behind a stair. While one foot on the ground, put the other foot on the stair and flex the knee about 45° flexion. Raise the body to full knee extension at one leg in 60 seconds and slowly lowering the body to 45° knee flexion in 60 seconds. During the exercises, the patient should control his/her lower leg to keep straight (keep away from varus/valgus)
Stair exercise (2): stand on a stair. Lower the body at one leg in 60 seconds and slowly turn and raise the body in 60 seconds During the exercises, the patient should control his/her lower leg to keep straight (keep away from varus/valgus)

To 9th month(3) running program (started at the 13th week)
(4) jumping (multidirectional) (started at the 18th week)
(5) plyometrics and agility exercises (started at the 20th to 24th week)
Restriction: return to sports is not allowed before 9 months after surgery
