Total hip replacement (THR) is one of the most successful operations in orthopaedics - the functional recovery curve is steep and most patients are back to near-normal daily activity by 3 months.

But the first 12 weeks have specific milestones and a few non-negotiable precautions that matter for a good long-term outcome.

This is the standard rehab pathway we run for THR patients in our Johor network.

Understanding the two surgical approaches

Posterior approach (traditional) - the surgeon enters from behind the hip. Faster, technically simpler, used at most Johor hospitals.

Carries "hip precautions" for 6–12 weeks: no hip flexion beyond 90°, no hip adduction across the midline, no internal rotation.

Anterior approach (increasingly common) - the surgeon enters from the front. No muscle cutting, faster early recovery, and usually no or fewer precautions.

Used at KPJ Johor Specialist, Regency, Gleneagles Medini, Columbia Asia Iskandar in most modern practices. Check with your specific surgeon which approach was used.

The rehab week-by-week is broadly similar, but the posterior approach needs strict precaution compliance in the first 6 weeks.

Week-by-week milestones

Week 1 (inpatient + first outpatient): Safe transfers bed to chair to toilet, walking with frame or crutches, independent with basic daily activities. Hip precautions drilled daily.
Weeks 2–4: Walking distance builds - from 50 m to 500 m. Single crutch usually by week 3. Full hip flexion to 90° (not beyond until precautions lift). Stairs one-at-a-time with rails.
Weeks 5–8: Crutches usually off. Walking 1–2 km comfortably. Stairs alternate-foot with rails. Return to driving (for a right hip, check with surgeon - typically 4–6 weeks).
Weeks 9–12: Return to most daily activities, light cycling, swimming once wound is fully sealed. Posterior-approach precautions typically lifted at 6–12 weeks per surgeon.
Months 3–6: Return to golf, gentle hiking, low-impact sport. Avoid deep hip flexion activities (squat-toilet, low-car seating) unless cleared by surgeon.

By 12 weeks, most uncomplicated THR patients are walking normally without aid, back at desk-based work, and managing all basic activities.

The remaining gains (strength, endurance, confidence) come over the next 3–6 months.

Hip precautions - what they actually mean

For posterior-approach patients during the precaution window:

No hip flexion past 90°. No squatting below knee level, no deep low chairs, no leaning forward from a chair to tie shoes.
No crossing legs. No cross-legged sitting, no "4" leg position.
No internal rotation. Don't twist to get in or out of a low seat.

Practical adaptations for the first 6 weeks: a raised toilet seat, a firm high chair, no driving in a low sports car, sleeping on the back or the unoperated side with a pillow between the knees.

Typical Johor RM costs

THR surgery at private hospital: RM 30,000–55,000 bundle. HSA is subsidised.
Outpatient rehab: 14–20 sessions at RM120-250 over 12 weeks.
Home-visit rehab (for the first 2–3 weeks): RM120-250 per session, common for older patients.

Red flags during THR rehab

Call the surgeon, not the physio, if any of these appear:

Calf pain/swelling/warmth on one side (DVT).
Sudden increase in hip pain, especially with a pop sensation (possible dislocation in posterior approach).
Fever + wound redness, warmth, discharge (possible infection).
Chest pain or shortness of breath (possible PE).

How PhysioJohor matches THR patients

WhatsApp us with: which hospital, which surgeon, surgical approach (posterior or anterior), date of surgery, and current mobility status.

We match to a physio experienced in your surgeon's protocol and coordinate home-visit or clinic delivery based on your mobility.
