Table 2 The number of patients undergoing the different examinations and the number and percentage of positive and negative results from each examination

From: Hip-related groin pain, patient characteristics and patient-reported outcomes in patients referred to tertiary care due to longstanding hip and groin pain: a cross-sectional study

  Patients n Positive result n (%) Negative result n (%)
Criterion 1
 Affected hip ROM 81 71 (88) 10 (12)
Criterion 2
 Pain during any of the impingement test 81 76 (94) 5 (6)
Criterion 3
 Radiographic data. Alfa angle > 60 (CAM morphology) 75a 34 (45) 41 (55)
 Radiographic data. LCE angle > 40 (Pincer morphology) 79b 19 (24) 60 (76)
 Radiographic data. LCE angle < 20 (Dysplasia) 79b 1 (1) 78 (99)
 Findings on MRI corresponding to hip-related pathology 54c 19 (35) 35 (65)
 Findings during arthroscopy corresponding to hip-related pathology 19d 17 (89) 2 (11)
Criterion 4
 ≥ 50% decrease of patient reported pain from intra-articular block injection 70e 49 (70) 21 (30)
Criteria 1 + 2 + 3 + 4 70 33 (47) 37 (53)
  1. LCE angle = Lateral center-edge angle
  2. a Missing data (n = 6) due to missing radiographs or missing Lauenstein projection
  3. b Missing data (n = 3) due to missing radiographs
  4. c Missing data (n = 27) due to missing clinical relevance for the examination
  5. d Missing data (n = 62) due to missing clinical relevance for the examination
  6. e Missing data (n = 11) due to either declined injection or failure to complete VAS scoring after the injection
