Correction to: Knee Surgery, Sports Traumatology, Arthroscopy

Authors would like to correct the figure caption of Fig. 1 and Fig. 2 which have been mixed up in the published version. The corrected version updated here.

Triage algorithm for patients’ suspect of joint related hip pain using a standardized pelvis X-ray as it has been formally approved on a national consensus meeting in 2016. As certain surgical procedures as PAO and hip arthroscopy exclusively can be treated at a limited number of highly specialized orthopaedic departments agreeing on specific referral criteria, increases the chance that Danish patients will be seen at a department most likely to be responsible for the entire treatment. However, this algorithm is solely a guide for the referral of a patient. Patients with radiological signs of AR may still receive a hip arthroscopy

Flowchart with inclusion-and exclusion criteria as well as amount of patients with radiological signs of retroversion [combinations of positive posterior wall sign (+ PWS) and/or ischial spine sign (+ ISS)] at the different time points (T0 = preoperative, T1 = 1 year postoperative, T2 = 2 years postoperative). True acetabular retroversion was defined as a combination of + PWS and + ISS, while no retroversion was defined as the absence of both signs (− PWS, − ISS)
