Table 2 Clinical and functional improvement of both groups at the last follow-up (mean ± SD)

From: Arthroscopic arthrolysis of posttraumatic and non-traumatic elbow stiffness offers comparable clinical outcomes

Parameters Posttraumatic group (n = 75) Non-traumatic group (n = 68) P-value
Extension 29.4 ± 20.6 (− 15–85) 25.2 ± 24.5 (− 30–90) 0.27
Flexion 34.6 ± 23.9 (0–100) 29.7 ± 26.2 (−20–115) 0.29
ROM 63.8 ± 26.3 (−5–115) 54.5 ± 35.7 (− 20–115) 0.08
MEPI 29.0 ± 11.5 (0–60) 26.6 ± 11.3 (5–55) 0.21
  1. No statistical significant differences were observed in all the parameters
