Severe disability in primary osteoarthritis of hip is best managed by -

Intra-articular hydrocortisone and physiotherapy

A 70-year-old man has had a long-term "bowlegged" condition but recently his right knee has become warm, swollen, and tender. He reports no recent trauma and gets no relief with rest or Tylenol (paracetamol). He is otherwise in good health and takes no medication. X-rays show arthritis of the knee. Which would be the best treatment?

Use of a cane for ambulating, restriction of knee-bending activities, and implementation of muscle-strengthening exercises

Intra-articular steroid injection, bed rest, and analgesics

Bed rest, anti-inflammatory agents, analgesics, and a knee brace

Long-leg cast and crutches for 3 weeks, analgesics, and anti-inflammatory agents

Open reduction (OR) is not required in which fracture?

Fracture of the outer one-third of the radius

Displaced fracture of the olecranon

Fracture of the condyle of the humerus

Conservative Management of Degenerative Disorders: High-Yield Orthopaedics Lessons

Conservative Rx of Degenerative Disorders - Joint Reality Check

Osteoarthritis (OA): Most common degenerative joint disorder. Progressive cartilage loss, subchondral bone changes, osteophyte formation.

⭐ Osteoarthritis is the most common type of arthritis, primarily characterized by cartilage degeneration and osteophyte formation.
Clinical Impact: Chronic pain, stiffness (especially morning/inactivity), ↓ range of motion (ROM), functional limitation, impaired Quality of Life (QoL).
Commonly Affected Joints: Knees, hips, hands (DIP, PIP, CMC1), spine (facet, intervertebral discs).
Conservative Management Goals:
- Pain control & symptom relief
- Maintain/improve joint function & mobility
- Patient education on disease & self-care
- Enhance overall QoL
- Delay or avoid surgery.
Approach: Holistic, patient-centered, multimodal_approach tailored to individual needs and disease severity, focusing on non-pharmacological and pharmacological interventions before considering surgery_ (This part makes it slightly over 100, let's re-evaluate the last point for conciseness).

Conservative Rx of Degenerative Disorders - Lifestyle & Motion Magic

Lifestyle Modifications:
- Weight Loss: 5-10% body weight reduction ↓ pain, ↑ function in knee/hip OA.
- Activity Modification: Low-impact (e.g., swimming, cycling); avoid overuse, joint stressing activities.
- Patient Education: Disease understanding, self-management, joint protection techniques.
Exercise Therapy ("Motion Magic"):
- Goals: ↓ Pain, ↑ Function, ↑ Range of Motion (ROM), ↑ Muscle strength.
- Key types: Strengthening (esp. quadriceps, hip abductors), ROM exercises, low-impact aerobic conditioning (e.g., walking, aquatic).
⭐ Quadriceps strengthening is crucial for knee OA, significantly improving pain and function.
Assistive Devices:
- Canes (used in contralateral hand), walkers, crutches to offload joint.
- Braces (e.g., unloader knee brace for varus/valgus deformity), orthotics (e.g., shock-absorbing insoles).

Exercise in OA: Types & Benefits

Exercise Type	Benefit(s) in OA
Strengthening	↑ Joint stability, ↓ Pain, ↑ Function, Muscle support
Range of Motion (ROM)	Maintains/↑ joint mobility, ↓ Stiffness
Aerobic (Low-Impact)	↑ Cardiovascular fitness, Weight control, Mood boost
Hydrotherapy	↓ Joint load, Pain relief, Eases movement

Key Drug Classes for Osteoarthritis (OA) Management

Class	MOA	Examples	ADRs	Key Points
Analgesics	Central analgesic	Paracetamol	Hepatotoxicity (high dose)	Max 3-4g/day. Generally first-line for mild-moderate OA.
	Weak opioid, SNRI	Tramadol	Nausea, dizziness, seizure risk	Adjunct for moderate to severe pain.
NSAIDs	COX inhibition	Ibuprofen, Diclofenac (topical/oral), Celecoxib	GI, renal, CV risk	Lowest dose, shortest duration. Topical for localized OA. Consider PPI with oral.
IA Corticosteroids	Potent anti-inflammatory	Triamcinolone	Local pain, infection (rare)	Rapid relief (lasts 4-8 wks). Max 3-4/yr/joint.
IA Hyaluronic Acid	Viscosupplementation	Sodium Hyaluronate	Local reaction	Modest benefit, often delayed onset.
Duloxetine	SNRI	Duloxetine	Nausea, dry mouth, fatigue	For chronic pain, esp. if neuropathic component.

Conservative Rx of Degenerative Disorders - Support & Struts

Purpose: ↓Pain, ↑Stability, ↓Joint load, ↑Function.
Knee Braces:
- Unloader (Valgus/Varus): For unicompartmental OA.
  
  ⭐ Unloader braces shift the weight-bearing axis from the damaged to the healthy cartilage compartment.
- Patellofemoral: For patellofemoral OA/pain.
- Hinged: Provides mediolateral stability.
Spinal Orthoses:
- Cervical collars (soft/rigid): Limit motion, provide support.
- Lumbosacral corsets/belts: Support, proprioception, limit gross movement.
Foot & Ankle Orthotics:
- Arch supports, heel wedges, MCR insoles.
- AFOs (Ankle-Foot Orthoses): For foot drop, instability.
Hand & Wrist Splints:
- Thumb spica (CMC OA), wrist splints (e.g., carpal tunnel, wrist OA).
Assistive Devices:
- Canes, walkers, crutches: Reduce joint loading, improve balance.
  - Cane: Used in contralateral hand. 📌 (COAL: Cane Opposite Affected Leg)

High‑Yield Points - ⚡ Biggest Takeaways

Lifestyle modification (weight loss, activity adjustment) is first-line management.

NSAIDs and acetaminophen are key analgesics; COX-2 inhibitors for GI safety.

Intra-articular corticosteroids offer short-term pain relief (weeks to months).

Viscosupplementation (hyaluronic acid) shows variable efficacy for knee OA.

Physical therapy (strengthening, ROM exercises) is crucial for function.

Patient education and joint protection techniques are vital.

Assistive devices (canes, braces) reduce joint load and improve mobility.
