Dr Marcus Chia - Shoulder Surgeon
A rotator cuff tear is one of the most common causes of shoulder pain and weakness in adults. Dr Marcus Chia is a fellowship-trained shoulder surgeon based in Sydney who specialises in the diagnosis and treatment of rotator cuff tears — from conservative physiotherapy-guided management through to minimally invasive arthroscopic repair.
The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint, providing stability and enabling movement. A tear occurs when one or more of these tendons is partially or completely disrupted. There are two main types: • Partial thickness tear — the tendon is damaged but not fully torn • Full thickness (complete) tear — the tendon is torn all the way through or detached from the bone Rotator cuff tears can occur suddenly (acute, typically from a fall or injury) or develop gradually over time due to repetitive use and age-related degeneration.

The most common symptoms include shoulder pain (particularly at night or when lifting the arm), weakness in the shoulder, difficulty raising the arm above shoulder height, and a clicking or grinding sensation with movement. Pain may worsen gradually or appear suddenly following an injury.
Dr Chia will conduct a thorough physical examination assessing shoulder strength, range of motion, and specific clinical tests. This is typically followed by imaging — an MRI is the gold standard for diagnosing the size and location of a rotator cuff tear, while X-ray can identify associated bone changes.
No. Many rotator cuff tears — particularly partial tears and smaller full-thickness tears in older patients — can be successfully managed without surgery using physiotherapy, activity modification, and anti-inflammatory treatment. Dr Chia's physiotherapy background means he takes a genuinely conservative approach and will only recommend surgery when non-operative management has been exhausted or when the tear is likely to worsen without repair.
Most rotator cuff repairs are performed arthroscopically (keyhole surgery). Dr Chia inserts a small camera (arthroscope) into the shoulder through tiny incisions and uses specialised instruments to reattach the torn tendon to the bone using sutures and bone anchors. This minimally invasive approach reduces pain, scarring, and recovery time compared to open surgery.
Recovery varies depending on tear size and the patient's health. Most patients wear a sling for 4–6 weeks, begin physiotherapy soon after surgery, and return to light activities within 3 months. Full recovery and return to sport or heavy manual work typically takes 6–12 months.
Untreated full-thickness tears can enlarge over time, making repair more difficult or impossible. Chronic tears may lead to muscle wasting (fatty infiltration) and the development of rotator cuff tear arthropathy — a severe form of shoulder arthritis. Early assessment is important.
