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

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

	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)	75^a	34 (45)	41 (55)
Radiographic data. LCE angle > 40 (Pincer morphology)	79^b	19 (24)	60 (76)
Radiographic data. LCE angle < 20 (Dysplasia)	79^b	1 (1)	78 (99)
Findings on MRI corresponding to hip-related pathology	54^c	19 (35)	35 (65)
Findings during arthroscopy corresponding to hip-related pathology	19^d	17 (89)	2 (11)
Criterion 4
≥ 50% decrease of patient reported pain from intra-articular block injection	70^e	49 (70)	21 (30)
Criteria 1 + 2 + 3 + 4	70	33 (47)	37 (53)

LCE angle = Lateral center-edge angle
^a Missing data (n = 6) due to missing radiographs or missing Lauenstein projection
^b Missing data (n = 3) due to missing radiographs
^c Missing data (n = 27) due to missing clinical relevance for the examination
^d Missing data (n = 62) due to missing clinical relevance for the examination
^e Missing data (n = 11) due to either declined injection or failure to complete VAS scoring after the injection
