Week 3 Wound Infection Checks After Knee Replacement

After knee replacement surgery, week 3 marks a key healing stage. Your incision should show steady progress, but infections can still develop. Spotting knee replacement infection early matters. Home checks help you decide when to seek help.

This guide covers signs of infection after knee replacement in week 3. It gives steps for daily monitoring. Always get an in-person check for concerns. Physiotherapy supports recovery but does not replace doctor care.

Trivayu Physio Center in Vaishali Nagar and Vidyadhar Nagar treats post-surgery cases. Our team checks wounds during rehab visits.

Understanding Knee Replacement Infection Risks in Week 3

By week 3 post-knee replacement, the wound starts closing. Stitches or staples may come out soon. Skin edges pull together, and scab forms. Inside, tissues mend. The new joint settles as inflammation eases.

Infections can happen from bacteria entering the wound. Sources include poor hygiene or loose dressings. Week 3 risks rise as you move more. Sweating or rubbing from clothes can introduce germs. Activity loosens scabs, opening paths for bacteria.

Home monitoring spots changes early. Watch daily for knee replacement wound infection signs. Note new symptoms. Contact your clinic before issues grow. An in-person assessment confirms infection and guides steps. Physiotherapists check how infection affects movement. Looking for a Physiotherapy Clinic Near Me?

Key Signs of Wound Infection After Knee Replacement

Look for these signs of infection after knee replacement in week 3. Check your knee twice daily in good light. Use daylight or a bright lamp.

• Redness around knee incision: Streaks spreading from the cut. Week 3 redness should fade. Trace it; if it reaches beyond 5 cm from the incision, note it.
• Swelling after knee replacement: Puffiness increases suddenly, feels firm or hot. Press lightly; if it pits, track it.
• Warmth knee incision infection: Skin warmer than the other knee. Place the back of your hand on both knees to compare.
• Knee wound pus drainage: Thick yellow, green or cloudy fluid. A small wet spot on dressing signals this.
• Odour: Foul smell from the wound. Sniff near the dressing.

Pain increasing week 3 knee replacement counts too. Rest does not ease it. New chills or tiredness signal trouble. Track changes. Fever after knee surgery often pairs with these. A rise above 38°C needs attention. Weakness or night sweats add concern.

How to Monitor Your Knee Wound at Home

Follow these steps for home checks. Do them daily, same time, morning and evening. Wear gloves if hands have cuts.

1. Inspect the wound: Use a mirror or ask family. Note colour, size, edges. Photo it daily. Take pics from front, side and close-up. Store by date.
2. Feel gently: Touch edges for warmth or hardness. Compare sides. Wash hands with soap for 20 seconds. Do not press the centre if tender.
3. Measure temperature: Use a thermometer under tongue or arm. Track morning and evening. Clean with alcohol after use. Note if knee skin feels hotter.
4. Rate pain and swelling: Score pain 0-10. Measure knee with tape above and below patella. Record circumference in cm.

Call clinic if redness spreads, pus appears, fever hits 38°C or pain jumps 2+ points. Orthopaedic Rehabilitation at Trivayu guides safe loading on the new knee. Stop if checks hurt. Seek help same day for blisters or black edges.

Preventing Complications in Knee Replacement Recovery

Keep the area clean and dry. Change dressings as advised. Wash hands before touching. Use mild soap and pat dry.

• Move as guided: Short walks, no twisting. 10-15 minute walks on flat ground, 3-4 times daily. Use walker if prescribed.
• Elevate leg above heart 20 minutes, few times daily. Pillows under calf, not knee bend.
• Ice 15 minutes hourly if swelling mild. Wrap ice pack in cloth. Stop if numb.
• Avoid baths; showers only after okayed. Let water run over knee, no scrubbing. Dry fully.
• Wear loose cotton clothes. Avoid tight pants.

Electrotherapy at our center may ease pain. Recovery varies. Follow doctor plans. Bending knee beyond advised angle raises risks.

How Physiotherapists Approach Post-Op Infections

A physio asks about symptoms and reviews your log. They examine the wound without removing dressings unless trained. Expect questions: When did redness start? Does pain change with walking?

They test knee stability by moving it slowly. Manual Therapy might include light massage around the wound. They teach safe ways to sit from bed or climb stairs.

For swelling after knee replacement, physios show compression bandaging from ankle up. They monitor to adjust rehab pace. If fever persists, they refer to doctor.

When to see a doctor, not a physiotherapist

Physiotherapy is not the right first step for everything. Seek medical assessment promptly if any of the following apply to you:

• Pain following a significant fall, road accident or other major injury
• Fever, chills or feeling generally unwell alongside the pain
• Weakness that is getting worse, or numbness that is spreading

If you lose control of your bladder or bowels, develop numbness around the groin, or have chest pain or breathlessness, treat it as an emergency and go to hospital.

Safety limits and when this does not apply

• Any exercise that sharply increases your pain, or leaves it raised the following morning, is too much for now.
• Electrotherapy and laser therapy have their own restrictions, including pacemakers, pregnancy and treatment over a known tumour. Your physiotherapist screens for these before use.
• This article is general information. It is not an assessment of your problem, and it cannot account for your medical history, medication or imaging.
