🔍 Key Findings
- 48% of the intra-articular biceps tendon was visible at a standing angle; this increased to 63% in flexion (p = 0.0003).
- 58% of the medial glenohumeral ligament's cranial border was within view.
- 20% of the subscapularis tendon was visualized via the standard lateral arthroscopic approach.
- Visibility was assessed using tattoo ink markers and confirmed via dissection in cadavers.
- Limitations of standard lateral portals may lead to underdiagnosis of deeper or distal pathology in these structures.
