Total Hip Replacement Anterior Rehab Protocol

Download PDF to print

The intent of this protocol is to provide the clinician with a guideline for the post-operative rehabilitation course of a patient that has undergone a total hip arthroplasty. It is by no means a substitute for one’s clinical decision making regarding the progression of a patient’s post-operative course based on their physical exam/findings, individual progress, and/or the presence of post-operative complications. If a clinician requires assistance in the progression of a post-operative patient they should consult with the referring surgeon.

GENERAL GUIDELINES:

• Focus on protection of surgical site.
• Individualized gradual progression of therapy to promote optimal level of functional independence
• Supervised physical therapy takes place for 3-6 months.

GENERAL PROGRESSION OF ACTIVITIES OF DAILY LIVING (ADLs)

• No bathing/showering (sponge bath only) until after suture removal.  
• Driving: Return within 12 weeks of surgery, average around 4 weeks
• Weight-bearing as tolerated immediately post-op if no complications
• Wean from walker/rollator/cane or return to prior level of function for ambulation as treatment progresses 
• Return to normal daily activities/work as directed by PT/MD based on demands and goals.

Rehabilitation Progression

PHASE I: Week 0 – 6:

Goals:

• Protection of surgical site
• Improving safety with mobilization and transfers
• Decrease pain and inflammation
• Restore hip range of motion within precautions
• Prevent muscle atrophy
• Muscle re-education and motor control of post-op leg
• Educate patient on weight bearing status and hip precautions
• Normalize gait, gradual ween off of assistive device 
• Gradual progression of exercises to improve strength
• Initiate home exercise program of aerobic and light resistance training

Precautions:

• No active range of motion (AROM)/passive range of motion (PROM) hip extension past neutral
• Avoid passive hip external rotation
• Avoid prolonged sitting

Weight Bearing Status:

• Weight bearing as tolerated (WBAT) with walker or cane

Exercises:

• Gait training
• Ankle pumps
• Heel slides
• Straight leg raise
• Short arc quads
• Long arc quads
• Glute sets
• Weight shifts
• Mini-squats
• Hip hinge
• Forward, retro and lateral step downs
• Heel and toe raises
• Progressive hip abduction strength
• Core stabilization progression

Criteria to advance:

• No signs of infection
• No evidence of dislocation
• Demonstrate activation of surrounding hip muscles
• Tolerable pain if any with exercises

PHASE II: Weeks 6-9:

Goals:

• Protect surgical site
• Normal gait with no assistive device or prior assistive device
• Promote return of full hip range of motion
• Single leg balance with proper hip control
• Continue progressive home exercise program
• Restore functional hip strength

Precautions:

• Avoid aggressive or forceful hip extension 
• Hip range of motion precautions discontinued

Weight Bearing Status:

• Weight bearing as tolerated (WBAT)

Exercises:

• Continue prior exercises as needed with increased range of motion and intensity
• Dynamic balance activities
• Advanced open and closed chain hip abduction strengthening

Phase III:  Week 9 to 12:

Goals:

• Symmetrical hip ROM
• Able to tolerate 20 minute walk
• Up/down stairs without railing
• Hip strength at functional level
• Adequate range of motion for ADL’s, gait and recreational activities
• Able to resume normal lifestyle without limitations in pain or weakness
• Progress home exercise program

Exercises:

• Progression of prior phase
• Advanced static and dynamic balance activities
• Include individualized recreational/ADL/work specific exercises

Phase IV:  3 to 6 Months:

Goals:

• Resume normal lifestyle of work, ADL’s and recreation
• Patient independent with home exercise program for continued improvements of strength, balance and cardiovascular exercise
• Maintain cardiovascular stamina and hip strength
• Maintain balance to prevent falls and/or hip fractures

Exercises:

• Progression of previous phase
• Higher level recreation/ADL/work specific exercises
