PIP for Knee or Hip Replacement - Before, During and After Surgery

Joint replacement surgery - whether knee, hip, shoulder or ankle - creates significant PIP-eligible difficulties before, during recovery and often permanently afterwards. Many people assume a replacement "fixes" everything and don't claim. In reality, recovery takes 6-12 months and many people never regain full function.

Before Surgery

If you're on the waiting list for a joint replacement, your condition is already severe enough to warrant surgery. The pain, stiffness and mobility limitations that led to the surgical decision are all PIP-relevant. Don't wait until after surgery to claim - claim now based on your current difficulties.

During Recovery (0-12 Months Post-Surgery)

The first 3 months after joint replacement are the most disabling. You cannot:

• Walk more than a few metres without a frame or crutches
• Bend to put on socks, shoes or trousers
• Get in or out of a bath
• Stand long enough to cook
• Drive (typically 6-12 weeks)

The difficulties in this period can score well, but PIP has a required period: your limitations must already have lasted 3 months and be expected to last at least another 9, so a recovery expected to be complete within a few months does not qualify on its own. What usually meets the test is the limitation you already had before surgery, continuing through recovery and beyond. Even at 6-12 months, most people still have significant restrictions - ongoing pain, stiffness, limited bending and reduced walking distance.

After Recovery

A replacement joint is not a normal joint. You may have permanent restrictions: limited bending (especially after knee replacement), inability to kneel, ongoing pain especially in cold weather, risk of dislocation (hip replacement) and reduced walking distance compared to someone without joint problems. If these restrictions affect your daily life on the majority of days, PIP still applies.

Which Activities Are Affected?

Moving Around (Activity 12) - Reduced walking distance, unsteady gait, use of walking aids. Even after full recovery, many people can't walk as far as before.

Washing and Bathing (Activity 4) - Can't get in/out of bath. Difficulty bending in shower. Need for shower seat and grab rails.

Dressing (Activity 6) - Can't bend to put on socks, shoes, trousers. Need sock aids, long shoe horns and sometimes help from another person.

Preparing Food (Activity 1) - Standing tolerance reduced. Can't bend to oven. Difficulty carrying heavy items.

Managing Therapy (Activity 3) - Daily physiotherapy exercises and wound care count as therapy (descriptors 3c to 3f) only if another person has to supervise, prompt or help you with them at home, scored by the hours of their help each week. Needing reminders or help with pain medication is descriptor 3b (1 point). Hospital follow-ups do not count under this activity.

What If PIP Says I'm "Better" After Surgery?

At your next PIP review, the DWP may argue that your joint replacement has improved your condition. Challenge this if it's not true. Get your surgeon to write a letter confirming what permanent restrictions remain. "Improved" doesn't mean "cured" - if you still have difficulties on the majority of days, you still qualify.

Recovery Timeline by Joint and Surgery Type

• Knee replacement (TKR): Full recovery 6-12 months. 80-85% satisfaction rate. Limited kneeling permanently.
• Partial knee replacement (UKR): Faster recovery 3-6 months. Often used for younger patients.
• Hip replacement (THR): Recovery 3-6 months. Dislocation risk in first 6 weeks. Hip precautions to follow.
• Hip resurfacing: Younger patients. Better range of motion.
• Shoulder replacement: 6-12 months recovery. Limited overhead reach permanently.
• Ankle replacement: Less common. 6-12 months recovery. Limited flexion permanently.
• Revision surgery: Worse function and longer recovery than primary surgery. Many continue qualifying long-term.

Permanent Restrictions After Joint Replacement

• Knee replacement: Cannot kneel comfortably. Limited bending (90-120 degrees typical). Cannot squat. Avoid high-impact activities (running, contact sports).
• Hip replacement: Cross-leg restriction. Cannot bend hip past 90 degrees (varies by approach). Avoid high-impact. Lifelong infection precautions (antibiotic prophylaxis for dental work).
• Shoulder replacement: Cannot reach above shoulder height fully. Cannot lift heavy weights. Limited overhead activities.
• All joints: Risk of loosening over 10-20 years. Possible revision surgery. Stiffness in cold weather. Climate-sensitive pain.

Complications That Continue PIP Eligibility

• Chronic pain: 10-20% of TKR patients have persistent pain. Higher rates for revision surgery.
• Stiffness: Manipulation under anaesthesia sometimes needed.
• Infection: 1-2% rate. Often requires revision surgery and prolonged IV antibiotics.
• Loosening: Over time, prostheses can loosen requiring revision.
• Periprosthetic fractures: Bone breaks around implant.
• Nerve damage: Foot drop after knee surgery, sciatic nerve issues after hip surgery.
• DVT/PE: Blood clot risk. Anticoagulant management.
• Heterotopic ossification: Extra bone growth limiting movement.
• Hardware-related symptoms: Click, snap, give-way feelings.

Why People with Multiple Joints Replaced Often Qualify Long-Term

Many arthritis patients have multiple joints replaced:

• Bilateral knee replacements
• Bilateral hip replacements
• Knee + hip combination
• Plus other affected (unreplaced) joints (small joints of hands/feet, spine)

The combined impact of multiple joint replacements plus underlying inflammatory arthritis (RA, psoriatic, AS) often justifies continued PIP at enhanced rates.

Pre-Surgery PIP Strategy

If you are waiting for joint replacement:

1. Claim PIP immediately based on current function - severe pre-op disability is PIP-eligible
2. Get on the surgical waiting list as early as possible
3. Continue PIP through recovery - your function will deteriorate immediately post-op before improving
4. At review post-recovery, document any residual restrictions honestly
5. Many people retain PIP awards long-term because of other joint problems, age-related decline or surgical complications

Frequently Asked Questions

My surgeon says the operation was a success. Can I still claim?

A successful operation doesn't mean full recovery. Most people have ongoing pain, restricted bending, inability to kneel and reduced walking distance after knee replacement. "Successful" means the joint was replaced without complications - not that you can function like before. Describe your remaining limitations honestly.

I need a knee replacement but I'm on the waiting list. Can I claim now?

Yes, claim immediately based on your current condition. The pain, mobility problems and daily difficulties that led to the surgical decision are all PIP-claimable right now. Your back payment will cover from your claim date, including the surgical recovery period.

How long are NHS waiting lists for joint replacement?

2026 NHS waiting times average 12-24 months for routine TKR/THR. Some regions over 36 months. You may be eligible for treatment in another area if your local wait is excessive. Patient choice rules allow this.

Can I get private joint surgery using my PIP money?

PIP is not earmarked - you can spend it on private surgery if you choose. Private TKR/THR costs £12,000-£18,000 in the UK. Some choose to combine NHS PIP with private surgery to avoid waiting lists.

What if I have complications from surgery?

Surgical complications often extend recovery and may cause permanent additional impairment. Document any complications (infection, dislocation, nerve damage, persistent pain) on review. Many people who had complications continue to qualify for PIP indefinitely.

My PIP was reduced after my hip replacement - what do I do?

Request MR within one month of decision letter. Get orthopaedic letter confirming residual restrictions. Many people are awarded back original rates after MR or tribunal because the DWP underestimated post-surgery restrictions.

I have arthritis in other joints too - does that matter?

Significantly. If you have multi-joint disease (commonly RA, OA or PsA), replacement of one joint does not fix the others. Many claimants retain enhanced PIP because of combined arthritis across joints.
