The intra‐articular capacity of the elbow joint is reported to be 23 ± 4 ml on cadaveric elbows. During years, this value was the standard. The aim of this observational study was to reanalyze the volume of the elbow joint on live patients. Measurement of the intra‐articular capacity and pressure of the elbow joint was performed on 30 patients (mean age: 43.8 years) undergoing elbow arthroscopy. Intra‐articular capacity was recorded when the elbow moved to the maximum lose packed position and/or when there was a sudden drop in pressure, indicating a capsular rupture (maximum capacity). Indications for arthroscopy were loose bodies, osteoarthritis, synovitis, radial head resection, and lateral collateral ligament repair. Mean intra‐articular capacity and pressure were 35.8 ml and 557.5 mm Hg, respectively. Mean maximal capacity was 40.5 ml. We conclude that the intra‐articular capacity of the elbow joint is substantially greater than reported in previous studies. Clin. Anat. 30:795–798, 2017. © 2017Wiley Periodicals, Inc.
