Table 2 Comparison of pre- to postoperative proprioception differences between the STEMLESS and the CONTROL group

From: Are there differences between stemless and conventional stemmed shoulder prostheses in the treatment of glenohumeral osteoarthritis?

  STEMLESS (TESS®) CONTROL (Aequalis®) p-value
Movement Diff. [°] SD [°] Diff. [°] SD [°]  
30° of flexion 0.3 ±6.7 0.4 ±6.1 0.967
60° of flexion 1.5 ±3.4 0.3 ±3.9 0.453
30° of abduction 0.1 ±4.0 2.2 ±3.8 0.194
60° of abduction −0.6 ±2.3 1.8 ±2.8 0.061
30° of external rotation 3.4 ±7.4 −2.2 ±9.1 0.134
30° of internal rotation 1.7 ±3.0 3.2 ±6.9 0.510
Total proprioception 1.3 ±3.1 1.4 ±2.7 0.935
  1. Diff pre- to postoperative differences, SD standard deviation; Positive values indicate a deterioration of proprioception
