Danish Hip Arthroscopy Registry:
An epidemiologic and perioperative description of the first two thousand procedures.
19
Danish Hip Arthroscopy Registry (DHAR) was initiated in 2012 as a web-based prospective
20
registry. The purpose of this study was to evaluate and report the epidemiologic and perioperative
21
data of the first two thousand procedures in a Danish hip arthroscopy population and to describe
22
the development of DHAR. We describe the use of various Patient Related Outcome Measures
23
(PROM) related to non-arthritic hip patients.

Abstract
24
25
The 2000 procedures consisted of 56% females and 44% males. Mean age 37.5 years. Mean
26
surgical time was 86.5 minutes and mean traction time 50.5 minutes. The most frequent performed
27
procedure was CAM and Pincer resection in 93.5 % of the cases. Labral refixation or repair was
28
done in 70.3 % of the cases. The most common type of acetabular chondral damage was grade II
29
lesions (36.6 %). Grade III and IV changes were seen in 36.1 % of the cases. The preoperative
30
iHOT12 was 45 (mean) based on all 12 items. EQ-5D was 0.65 and HAGOS sub-scores were 51
31
(pain), 49 (symptoms), 53 (ADL), 35 (sport), 20 (physical activity) and 29 (QoL) respectively.
32
33
We conclude that patients undergoing hip arthroscopy report considerable pain, loss of function,
34
reduced level of activity and reduced quality of life prior to surgery. The problems with
35
development and maintaining a large clinical registry is described and further studies are needed to
36
validate data completeness. We consider the development of a national clinical registry for hip
37
arthroscopy as a successful way of developing and maintaining a valuable clinical and scientific
38
tool.
