1 Overview: what is osteoarthritis? ā–¾

Osteoarthritis (OA) is ā€œwear-and-repairā€ arthritis. The smooth cartilage that cushions a joint thins over time. Nearby bone and soft tissues react, causing pain, stiffness, swelling, and sometimes grinding or clicking. OA most often affects knees, hips, hands (base of thumb, finger joints), big toe, and spine.

  • Common signs: pain with use that eases with rest, morning stiffness < 30ā€“60 minutes, swelling after activity, reduced movement.
  • Risk factors: age, prior joint injury, extra body weight, family tendency, heavy/repetitive joint load, weak muscles.
2 Symptoms ā€” by joint ā–¾

Knee & Hip

  • Knee: pain climbing stairs, getting up from chair, squatting; occasional giving way; swelling after walks.
  • Hip: groin or side-hip ache, pain putting on socks or getting into a car; reduced stride length.

Hands & Spine

  • Thumb base (CMC): pinch/grip pain Opening jars, turning keys.
  • Fingers: bony knuckles (Heberden/Bouchard nodes), stiffness.
  • Spine: stiffness after sitting, low-back ache with standing/walking.
Pattern matters: OA pain is usually mechanical (worse with use). Constant night pain, fever, hot/red joints, or rapid swelling may suggest other problemsā€”seek care.
3 Diagnosis & imaging (do I need an MRI?) ā–¾

OA is a clinical diagnosis (symptoms + exam). X-rays can show joint space narrowing, bone spurs, and alignment. MRI is not usually needed unless symptoms donā€™t fit OA, thereā€™s locking/catching, or surgery is being planned.

Blood testsRule out other causesUsed when symptoms atypical

Imaging severity doesnā€™t always match pain. Treatment focuses on function and comfort.

4 Daily movement plan (short & gentle) ā–¾

Everyday

  • šŸŽÆ Goal: 20ā€“30 min of easy movement daily (can split into 3 Ɨ 10 minutes).
  • Walk on level ground, cycle on a stationary bike, or try water walking / light swim.
  • Keep pain ā‰¤ 4/10 during and after. If higher, shorten and slow.

Strength (2ā€“3Ɨ/week)

  • Chair sit-to-stand, wall push-ups, step-ups (low step), mini-squats holding a counter.
  • Two sets of 6ā€“10 reps; rest between sets. Quality over speed.

Mobility & balance

  • Knee: heel slides, calf/hamstring stretch.
  • Hip: gentle hip flexor and glute stretch.
  • Balance: stand near counterā€”one-leg stance 10ā€“20 sec each side.

5 Pain relief options (safer first) ā–¾

Non-drug first line

  • Heat for stiffness (warm shower or heating pad 10ā€“15 min).
  • Ice for flare swelling (10ā€“15 min with cloth barrier).
  • Topical NSAIDs (e.g., diclofenac gel for knees/hands) ā€” less whole-body exposure than pills.
  • Bracing & sleeves: patellar strap or knee sleeve; thumb CMC brace for grip tasks.
  • Footwear: cushioned, supportive shoes; consider lateral wedge for knee OA if advised.

Medicines (talk to your clinician)

  • Acetaminophen (paracetamol) may help mild pain; watch liver dose limits.
  • Oral NSAIDs (e.g., ibuprofen, naproxen) can help but may raise risks for stomach, kidney, heartā€”ask if safe for you.
  • Duloxetine can help chronic OA pain for some people.
  • Opioids are generally not first-line for OAā€”risks often outweigh benefits.
Safety: If you have kidney disease, heart failure, stomach bleeding history, or are on blood thinners, do not start oral NSAIDs without medical advice.
6 Managing flares (short plan) ā–¾
  1. Calm the joint: reduce load 24ā€“72 hours, switch to easier activities (cycling, pool).
  2. Ice 10ā€“15 minutes 2ā€“3Ɨ daily; elevate if swollen.
  3. Topical NSAID per label; ask about short NSAID course only if safe for you.
  4. Gentle range-of-motion once pain starts easing; resume strengthening slowly.

Severe swelling, warmth, redness, fever, or inability to bear weightā€”seek urgent evaluation.

7 Joint protection, devices, and home fixes ā–¾

Smart positions

  • Use hips and core, not small hand joints, for heavy tasks.
  • Avoid deep knee bend holds; change positions often.
  • ā€œNose over toesā€ when standing from chair to spare knees.

Helpful devices

  • Jar opener, key turner, reacher, raised toilet seat, tub bench.
  • Cane on the opposite side of the painful hip/knee.
  • Thumb CMC brace for pinch tasks (short bursts).

At home

  • Raise seat height (firm cushion) to ease sit-to-stand.
  • Non-slip mats, clear pathways, sturdy handrails.
  • Keep daily items at waist height to avoid deep bending.
8 Weight, sleep, and mood (quiet helpers) ā–¾
  • Small weight changes help knees/hips: even 5ā€“10 lb loss can reduce joint load and pain.
  • Sleep first: regular schedule, cool dark room, gentle stretch before bed; sleep and pain influence each other.
  • Stress care: brief daily breathing practice, pleasant walks, and connection with others ease pain perception.
9 Injections & procedures (who benefits?) ā–¾

Corticosteroid injections

  • May calm a hot, swollen OA flare (especially knee).
  • Relief is temporary (weeks to a few months for some).
  • Limits per yearā€”ask your clinician.

Viscosupplement (hyaluronic acid)

  • ā€œLubricatingā€ injections for knee OA; mixed evidence.
  • Some patients report modest benefit; coverage varies.

Surgery (when to think about it)

  • Strong pain most days, limited walking/ADLs, and non-surgical care hasnā€™t helped.
  • Knee or hip replacement can restore function for many; discuss risks, rehab, and support at home.
10 Red flags & when to seek urgent care ā–¾
  • Sudden hot, red, very swollen joint (especially with fever).
  • Inability to bear weight after a minor fall or twist.
  • Rapid joint deformity, severe night pain, or new numbness/weakness.
Call now: High fever, severe unrelenting pain, or suspected fracture.
11 Food & supplements (what actually helps) ā–¾
  • Build meals around vegetables/fruit, lean proteins, beans, oats/whole grains you tolerate, and healthy fats (olive oil, nuts).
  • Limit heavy ultra-processed snacks and sugary drinks that can worsen weight and inflammation feelings.
  • Supplements have mixed evidence. If you try one, trial one at a time, track benefit, and check safety with your clinicianā€”especially if you take blood thinners or have kidney/liver issues.

No supplement replaces movement, sleep, and weight care for OA.

12 FAQs ā–¾

Can cartilage grow back?

OA cartilage loss is usually permanent. The goal is to improve comfort and function by strengthening muscles, optimizing weight, using pain-relief strategies, and protecting the joint.

Is exercise safe if my knee hurts?

Yesā€”when done gently and consistently. Keep pain ā‰¤ 4/10 and avoid next-day spikes. Short, frequent sessions are better than long, occasional ones.

Do I need a knee brace?

Some braces or sleeves provide support and confidence, especially during activity. Theyā€™re an add-onā€”still do strength and mobility work.
