Hip Replacement Rehabilitation Guide
A comprehensive 12-week rehabilitation protocol following total hip arthroplasty. From immediate post-op care to return to normal activities.
Understanding Your Hip Replacement
Total hip arthroplasty (THA) is one of orthopedics' most successful procedures. The damaged hip joint—worn from arthritis, fracture, or other conditions—is replaced with metal and plastic components. The femoral head (ball) is replaced with a metal or ceramic ball on a stem that sits in your thigh bone. The socket (acetabulum) is resurfaced with a metal cup lined with plastic or ceramic.
Think of your hip as a ball-and-socket joint. When the surfaces are worn and rough, every movement grinds and causes pain. Hip replacement creates new, smooth articulating surfaces that glide instead of grind. But surgery is just step one. The muscles around your hip have been cut, stretched, or weakened. The ligaments have been disrupted. Your brain has learned protective movement patterns that limit function. Rehabilitation rebuilds strength, restores mobility, and retrains normal movement patterns.
Unlike knee replacement where motion is the early priority, hip replacement emphasizes stability. The new hip is at risk for dislocation until tissues heal and scar tissue forms to stabilize the joint. This creates unique challenges—preventing dislocation while regaining mobility. The balance requires following precautions precisely while progressively challenging the hip.
Anterior vs. Posterior Approach: Why It Matters
Your surgical approach (how surgeon accessed your hip) affects your precautions and recovery. Posterior approach (through buttock muscles): higher dislocation risk, strict precautions needed for 12 weeks (don't bend past 90°, don't cross legs, don't twist internally). Anterior approach (through front of hip): lower dislocation risk, fewer precautions, faster initial recovery. Direct lateral (through side): intermediate risk and precautions. Know your approach—precautions differ significantly. This guide covers general principles, but always follow your surgeon's specific instructions."
Recovery Timeline Overview
Understanding what to expect at each stage helps you stay on track:
Understanding Your Results (weeks)
Wound healing, pain control, hip precautions, walker/crutch ambulation
Progress to cane/single crutch, wean from walker, normalize gait pattern
Advanced strengthening, walk unassisted, return to most activities
Full functional mobility, return to recreational activities, maintain outcomes
Hip Precautions: What They Mean and Why
If you had a posterior approach, hip precautions are critical for preventing dislocation while tissues heal.
Hip Precautions (Posterior Approach)
| Factor | Effect | What to Do |
|---|
Always tell your doctor about medications, supplements, and recent health events before testing.
Week 0-2: Protection Phase
The goals are simple but critical: wound healing, pain control, and early mobility with precautions.
Daily Milestones
Week 0-2 Priorities and Actions

Always tell your doctor about medications, supplements, and recent health events before testing.
Essential Exercises (Weeks 0-2)
Ankle Pumps (DVT prevention):
- Move foot up and down vigorously
- Pump ankle like pressing gas pedal
- 20 reps every hour while awake
- Prevents blood clots
Gluteal Sets:
- Squeeze buttocks together tightly
- Hold 5 seconds, relax
- 10-15 reps, 3 times daily
- Activates hip stabilizers
Quad Sets:
- Sit or lie with leg extended
- Push knee down into surface, tightening thigh
- Hold 5 seconds, relax
- 10-15 reps, 3 times daily
Standing Hip Abduction (holding support):
- Stand holding counter or walker
- Move surgical leg outward sideways
- Keep knee straight, body still
- Don't lean—only leg moves
- 10 reps, 2 times daily
Clamshells (if precautions allow):
- Lie on non-surgical side with knees bent
- Keep feet touching, lift surgical knee
- Opens like clamshell
- Don't rock backward—only hip moves
- 10-15 reps, 2 times daily
Week 2-6: Mobility Phase
This is where most people see dramatic improvement. Focus shifts from protection to progression.
Mobility Progression
Key Exercises (Weeks 2-6)
Standing Hip Extension:
- Stand holding counter for support
- Move surgical leg backward slowly
- Keep knee straight, don't arch back
- Feel glute squeeze
- 10-15 reps, 2 times daily
Standing Hip Abduction (progressed):
- Stand holding counter
- Move surgical leg outward sideways
- Add light ankle weight as able
- 2 sets of 15 reps, 2 times daily
Mini Squats (if precautions allow):
- Stand holding counter for support
- Squat slightly, bending hips and knees 20-30 degrees
- Keep surgical leg aligned—don't let knee cave inward
- Avoid deep bending (>90°)
- 2 sets of 10-15 reps, 2 times daily
Single Leg Balance:
- Stand near wall or counter for safety
- Balance on surgical leg, progress to 30+ seconds
- Improves stability and confidence
- 2 sets of 5 reps, 2 times daily
Bridge (if precautions allow):
- Lie on back, knees bent, feet flat
- Lift hips toward ceiling
- Squeeze glutes at top
- Keep surgical leg within safe range
- 2 sets of 10-15 reps, 2 times daily
Week 6-12: Strengthening Phase
Now that mobility is established and precautions may be relaxing, focus shifts to strength and endurance.
Strengthening Progression

Always tell your doctor about medications, supplements, and recent health events before testing.
Driving and Return to Work
Driving:
- Right hip surgery: 4-6 weeks before driving
- Left hip surgery: 2-3 weeks (automatic transmission)
- Requirements: Off narcotic medications, adequate reaction time, sufficient strength to brake firmly
- Test in empty parking lot before driving on roads
Return to work:
- Desk job: 4-6 weeks
- Light duty: 6-8 weeks
- Heavy labor: 3-4 months or permanent restrictions
- Discuss timing with your surgeon—individual factors matter
Expected Outcomes
By 3 months, most people achieve:
- Walk 1/4 mile or more without assistance
- Climb stairs normally (reciprocal pattern)
- Perform most daily activities independently
- Minimal pain with normal activities
- Hip motion within functional range
Full recovery continues for 6-12 months as strength, endurance, and confidence continue to improve.
Setting Realistic Expectations
Your new hip will feel different than your native hip. Some mild clicking or warmth is normal and may persist for months. Complete pain relief is not guaranteed—some people have mild aching with weather changes or overactivity. However, most people report significant improvement in pain and function compared to pre-surgery. Satisfaction rates are 90-95% at 10 years. The goal isn't a perfect hip, but a dramatically better hip that allows you to do what matters to you.
Long-Term Protection and Activity
Your hip replacement will last longer with some considerations:
Recommended activities (low impact):
- Walking
- Swimming
- Cycling
- Golf (with cart initially, progress to walking)
- Dancing (ballroom, not high-impact)
- Hiking on flat terrain
Activities to avoid or limit:
- High-impact activities: running, jumping sports
- Heavy lifting: >50-75 lbs repeatedly
- Deep squatting: respect implant limits
- High-risk falls: contact sports, rock climbing
- Extreme ranges: discuss with surgeon
Maintenance:
- Continue exercises 2-3 times weekly
- Maintain healthy weight (each extra pound adds ~3 lbs to hip)
- Report infections before dental/surgical procedures (antibiotics may be needed)
- Regular follow-up X-rays to monitor implant
Warning Signs: When to Seek Help
Red Flags That Require Medical Attention
Seek immediate care (ER) for:
- Sudden inability to bear weight: Possible dislocation, fracture, or implant problem—call surgeon or go to ER
- Shortness of breath or chest pain: Possible pulmonary embolus—call 911
- Sudden severe hip pain: Possible dislocation—don't move, call for help
Seek urgent care (surgeon's office) for:
- Increasing pain: Not improving or worsening after initial improvement
- New swelling: After period of minimal swelling
- Wound concerns: Drainage, increasing redness, warmth
- Clicking or popping: Especially if painful or new
- Instability: Feeling like hip might give way
