Arthroscopic Principles in Shoulder and Elbow Surgery
28 June 2026 · Surgeons & Fellows
Arthroscopy of the shoulder and elbow shares core principles with arthroscopy elsewhere, but the neurovascular proximity in both joints — particularly the elbow — demands a disciplined, systematic approach to portal placement and instrumentation.
Portal strategy
For the shoulder, standard posterior, anterior and lateral portals cover the majority of rotator cuff, labral and subacromial work; accessory portals (anterosuperior, Neviaser, Wilmington) are added based on the specific pathology being addressed, not used by default.
For the elbow, portal placement carries a narrower margin for error given the proximity of the ulnar, radial and median nerves. Establishing the proximal anteromedial portal first, with the joint distended, is a widely taught safety principle — distension increases the distance between the capsule and the neurovascular structures before any sharp instrument is introduced.
Visualisation and fluid management
Consistent visualisation depends as much on fluid management as camera technique — adequate inflow pressure, an efficient outflow pathway, and controlled hypotensive anaesthesia (where appropriate) all reduce bleeding into the joint and improve efficiency. In the elbow, extravasation risk is higher and should be monitored throughout the case, particularly in longer procedures.
Diagnostic sequence
A systematic diagnostic pass before addressing pathology — moving through the joint in a consistent order every time — reduces the risk of missing a secondary finding (a partial cuff tear, a loose body, chondral damage) that changes the surgical plan.
Where technology is changing this space
Pre-operative 3D reconstruction of complex intra-articular fracture patterns is increasingly used to plan portal placement and fragment-specific fixation strategy before entering the joint, particularly for arthroscopically-assisted fracture management. This is discussed further in our AI & Innovation Hub coverage of computer-assisted surgical planning.
