Shoulder pain that won’t go away is one of the most disruptive orthopaedic problems people deal with. It can wake you at night, make it hard to reach overhead, and limit how far you can lift your arm. In many cases, the cause is a rotator cuff injury. This may be tendinopathy, which is degeneration of the tendon without a full tear. It may also be a partial or full rotator cuff tear.
This guide is for people with rotator cuff shoulder pain in Castle Hill, Norwest, the Hills District, or the Southern Highlands. It explains what is happening in your shoulder and what your options are. It also looks at why more patients are now exploring regenerative treatments like PRP.
What Is the Rotator Cuff?
The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint. They hold the ball of the upper arm bone (humerus) securely in the shoulder socket. These tendons are the supraspinatus, infraspinatus, teres minor, and subscapularis. They work together to allow the shoulder’s wide range of motion while keeping the joint stable.
Because the shoulder is the most mobile joint in the body, the rotator cuff tendons are under constant stress. Over time — or through sudden injury — they can develop tears or undergo degenerative changes.
Types of Rotator Cuff Injury
- Rotator cuff tendinopathy — degeneration within the tendon fibres, causing pain and weakness without a full structural tear. Often caused by repetitive overhead activity or age-related wear
- Partial thickness tears — a tear that goes part-way through the tendon. Many people with partial tears do not require surgery and can be managed conservatively
- Full thickness tears — the tendon is completely torn. Small full-thickness tears can sometimes be managed without surgery, while large tears often require surgical repair
- Calcific tendinitis — calcium deposits form within the tendon, causing intense, acute pain
Common Symptoms
- Pain on the outside of the shoulder or upper arm, often worse when lifting the arm
- Night pain, particularly when lying on the affected shoulder
- Weakness when reaching overhead or behind the back
- A painful arc of movement — pain during a specific range of shoulder elevation
- A catching sensation or clicking in the shoulder
Conventional Treatment Options
The initial management of most rotator cuff injuries is conservative:
- Physiotherapy — a structured programme of rotator cuff strengthening and scapular stabilisation exercises is the cornerstone of treatment for tendinopathy and partial tears
- NSAIDs — anti-inflammatory medications provide pain relief but do not address the underlying tendon pathology
- Cortisone injections — effective for short-term pain relief, particularly in cases of subacromial bursitis accompanying the tendon problem. However, repeated cortisone injections into tendons can weaken them further
- Surgical repair — for large full-thickness tears or cases that have failed conservative management, arthroscopic surgery to reattach the torn tendon is sometimes necessary
The Problem with Tendon Healing
Tendons have a notoriously poor blood supply, which is why they heal slowly and incompletely. Degenerated tendon tissue, as seen in chronic tendinopathy, is structurally different from healthy tendon. It shows disorganised collagen fibres and abnormal blood vessel growth. This is why even diligent physiotherapy doesn’t always resolve the problem completely, and why symptoms so often recur.
This biological challenge is precisely what makes regenerative medicine an attractive option for tendon conditions.
How PRP Can Help Rotator Cuff Conditions
Platelet-Rich Plasma (PRP) therapy delivers a concentrated dose of your own growth factors directly into the damaged tendon tissue. These include platelet-derived growth factor (PDGF) and transforming growth factor-beta (TGF-β). These growth factors stimulate collagen synthesis, promote the regeneration of tendon fibres, and reduce the chronic inflammatory state that keeps tendinopathy pain going.
For partial rotator cuff tears and chronic rotator cuff tendinopathy, PRP has shown promising results in clinical studies. Patients report meaningful improvements in pain, strength, and function. It is typically used in combination with a structured physiotherapy programme for best results.
PRP is not a substitute for surgical repair of large tears. But many patients with tendinopathy or partial tears want to avoid surgery, or have not responded fully to physiotherapy and cortisone. For them, it represents a well-tolerated and biologically logical next step.
