Surgical Quick Fire

🦴 WHO REALLY NEEDS A TOTAL SHOULDER REPLACEMENT?

Not everyone with shoulder pain needs surgery.

Total Shoulder Replacement (Total Shoulder Arthroplasty) may be considered when a patient has:

🔹 Severe shoulder arthritis — significant cartilage loss and joint damage
🔹 Persistent pain — pain that continues despite appropriate non-surgical treatment
🔹 Significant stiffness — difficulty with everyday movements such as dressing, reaching, or lifting
🔹 Loss of function — shoulder problems substantially affecting daily activities and quality of life
🔹 Failure of conservative treatment — physiotherapy, activity modification, medications and injections have not provided adequate relief
🔹 Suitable shoulder anatomy and rotator cuff function — important factors when considering an anatomic total shoulder replacement

⚠️ Important: Having arthritis on an X-ray alone does not automatically mean you need a shoulder replacement.

The decision depends on the combination of symptoms, clinical examination, imaging, functional limitation, patient expectations and overall health.

💡 Anatomic Total Shoulder Replacement is generally designed to restore the shoulder’s natural ball-and-socket anatomy. In patients with significant rotator cuff deficiency, a reverse shoulder replacement may be a more appropriate option.

🦵 Total Knee Replacement: When Should Mobilisation Start?

After a Total Knee Replacement (TKR), early mobilisation is an important part of recovery.

🚶 Mobilisation should usually begin on the day of surgery or as soon as it is safe to do so, depending on the patient’s medical condition and local protocol.

Why early mobilisation matters:

✅ Reduces the risk of venous thromboembolism (DVT/PE)
✅ Helps prevent postoperative stiffness
✅ Promotes muscle activation and recovery
✅ Improves confidence with walking
✅ Helps patients return home sooner
✅ Supports early functional recovery

Patients are typically encouraged to:
➡️ Sit out of bed
➡️ Stand with assistance
➡️ Walk with an appropriate walking aid
➡️ Gradually increase walking distance
➡️ Begin prescribed knee exercises and physiotherapy

⚠️ Important: Mobilisation should be individualised according to pain, stability, medical status and the surgeon/physiotherapy team’s advice.

🦿 TKR recovery starts with movement — safely, progressively and early.

🦿 TOTAL KNEE REPLACEMENT — Restoring Motion. Relieving Pain.

What happens after the damaged knee has been replaced?

In a Total Knee Replacement, damaged joint surfaces are replaced with carefully engineered components that recreate the function of the knee joint.

🔹 Femoral component — replaces the damaged femoral surface
🔹 Tibial baseplate — provides a stable foundation
🔹 Polyethylene insert — creates a smooth bearing surface between the components
🔹 Precise alignment — allows controlled, stable knee movement

In this animation, watch the completed knee move from full extension to approximately 90° of flexion, demonstrating the smooth articulation of the prosthetic components.

🦴 TOTAL HIP REPLACEMENT – Acetabular Preparation: The Foundation of a Successful Hip Replacement

🧐 Did you know?

One of the most critical steps in a Total Hip Replacement happens before any implant is inserted.

After the damaged femoral head is removed, the surgeon carefully prepares the hip socket (acetabulum) using sequential hemispherical reamers. Each reamer gradually enlarges the socket while preserving healthy bone and restoring the hip’s natural centre of rotation.

Once the ideal size and orientation are achieved:
✅ A porous-coated titanium acetabular cup is implanted with a secure press-fit.
✅ If additional stability is needed, screws are inserted through the cup into the pelvic bone (ilium) to provide immediate fixation.
✅ Over time, bone grows into the porous surface of the implant, creating long-term biological fixation.

🎯 Proper cup position is essential because it influences:
• Hip stability
• Leg length
• Range of motion
• Implant longevity
• Risk of dislocation and wear

This video demonstrates the acetabular preparation and cup implantation stage of Total Hip Replacement for educational purposes.

❓ Question of the Day

🤔 Quick Orthopaedic Quiz!

A 38-year-old patient presents with deep buttock pain that worsens after prolonged sitting and occasionally radiates down the back of the thigh. Hip X-rays are normal.

What is the most likely diagnosis?

A. Greater Trochanteric Pain Syndrome (GTPS)
B. Piriformis Syndrome
C. Hip Osteoarthritis
D. Lumbar Disc Herniation

👇 Comment your answer below before reading further!

⸻

🩺 What is Piriformis Syndrome?

Piriformis syndrome occurs when the piriformis muscle, located deep in the buttock, irritates or compresses the sciatic nerve as it passes through the deep gluteal region.

Common Symptoms

✅ Deep buttock pain
✅ Pain after prolonged sitting or driving
✅ Pain that may radiate down the back of the thigh
✅ Tenderness over the deep buttock
✅ Pain reproduced by stretching or activating the piriformis muscle

Common Causes

• Repetitive overuse (running, cycling)
• Prolonged sitting
• Trauma to the buttock
• Muscle tightness or spasm
• Pregnancy-related biomechanical changes

How is it diagnosed?

Diagnosis is mainly clinical, supported by examination. MRI is often used to exclude other causes such as lumbar disc disease, hip pathology, or other deep gluteal conditions.

Treatment

✔️ Activity modification
✔️ Physiotherapy and piriformis stretching
✔️ Hip and core strengthening exercises
✔️ Anti-inflammatory medication when appropriate
✔️ Image-guided injections in selected patients
✔️ Surgery is rarely required

💡 Correct Answer: B. Piriformis Syndrome
