locked in full extension
• Prone hangs or heel propped in supine for passive knee exten-
sion

degrees/day
• Gait training with crutches and brace, level ground and stairs

tive hamstring autograft reconstruction)
Manual Therapy
• Continue patellar mobs as indicated.

• SLR without quad lag
• Normal gait pattern with single crutch and unlocked brace

Phase III (Weeks 2–4)

Weightbearing Status
• FWB, normal gait without assistive device or brace by 3 weeks
Exercises
• Stationary bike with gradual progressive resistance for endurance
• Isometric quad sets in full extension and at 90 to 60 degrees
flexion with and without NMES or biofeedback until equal quad
contraction bilaterally
• Closed kinetic chain squat/leg press 0 to 60 degrees, gradual
progressive resistance
• Balance board bilateral in multiple planes
• Single-leg balance eyes open/closed, variable surfaces
• Sport Cord or treadmill walking forward and backward
• Standing SLRs, each LE and with resistance
Manual Therapy
• Continue patellar mobilizations as indicated.
• Initiate scar mobilizations as needed.
• Manual extension or flexion ROM as needed
Goals
• Full AROM, equal to nonsurgical knee
• Normal gait without assistive device
• Independent activities of daily living (downstairs may still be difficult)

Phase IV (Weeks 4–8)

 Precautions
• State of graft at its weakest during this postoperative period.
No impact activities such as running, jumping, pivoting, or cut-
ting, and no deep squatting (limits remain 0–60 degrees)
• Pay attention to scar mobility; use manual soft tissue mobiliza-
tions as indicated
Exercises
• Stationary bike: increase resistance and some light intervals
• Squats/leg press: bilateral to unilateral (0–60 degrees) with pro-
gressive resistance
• Lunges (0–60 degrees)
• Stairs: concentric and eccentric (not to exceed 60 degrees of knee
flexion)
• Calf raises: bilateral to unilateral
• Contrakicks (steamboats) (Fig. 47.8): progress from anteroposte-
rior to side to side, then circles/random
• Rotational stability exercises: static lunge with lateral pulley
repetitions
• Sport Cord resisted walking all four directions
• Treadmill walking all four directions
• Balance board: multiple planes, bilateral stance
• Ball toss to mini-tramp or wall in single-leg stance
• Single-leg deadlifts (Fig. 47.9): wait for 6–8 weeks if hamstring
autograft
• Core strengthening: supine and prone bridging, standing with
pulleys
• Gait activities: cone obstacle courses at walking speeds in mul-
tiple planes .

Phase V (Weeks 8–12)

Things to Watch Out for
• Patellar tendinitis
Exercises
• Squats/leg press: bilateral to unilateral (0–60 degrees) progressive
resistance
• Lunges (0–60 degrees)
• Calf raises: bilateral to unilateral
• Advance hamstring strengthening
• Core strengthening
• Combine strength and balance (e.g., ball toss to trampoline on
balance board, mini-squat on balance board, Sport Cord cone
weaves, contrakicks)
• Advanced balance exercises (e.g., single-leg stance while reaching
to cones on floor with hands or opposite foot, single-leg stance
while pulling band laterally)
• Lap swimming generally fine with exception of breaststroke; cau-
tion with deep squat push-off and no use of fins yet
• Stationary bike intervals

month with good strength program)

Phase VI (Weeks 12–16)
Things to Watch Out for/Correct
• Landing during exercises at low knee flexion angles (too close to
extension)
• Landing during exercises with genu varum/valgum (watch for
dynamic valgus of knee and correct)

• Perturbation training*: balance board, roller board, roller board
with platform
• Shuttle jumping: bilateral to alternating to unilateral, emphasis
on landing form

phasis on landing form
• Jogging in place with Sport Cord: pulling from variable directions

• Hop testing†: 80% of uninvolved limb performed prior to running
Phase VII (Weeks 16–24)
Exercises
• Progressive running program‡
• Hop testing and training†
• Vertical, horizontal jumping from double to single leg
• Progressive plyometrics (e.g., box jumps, bounding, standing
jumps, jumps in place, depth jumps, squat jumps, scissor jumps,
jumping over barriers, skipping)
• Speed and agility drills (e.g., T-test, line drills) (make these simi-
lar in movement to specific sport of athlete)
• Cutting drills begin week 20
• Progress to sport-specific drills week 20
For Revision ACL Reconstructions
Per specific physician recommendation, follow typically similar proto-
col until 12 weeks, then extend weeks 12 to 16 through to 5- to 6-month
timeline, when patients can then begin running and progress to
functional sports activities. See Fig. 47.8 for an illustration of abduction
contrakicks/steamboats (flexion, extension, and adduction contrakicks
can be performed by rotating patient 90 degrees at a time
