Abstract
Objective To describe a postarthroscopic treatment classification system for acetabular chondral damage in the hip and to report the intraobserver and interobserver reliability of such classification.
Methods This is a retrospective review of ninety-nine digital video recordings made during arthroscopic surgery. Patients who underwent arthroscopic treatment for femoroacetabular impingement and evaluated at the hip arthroscopy outpatient clinic between March 2015 and March 2016 were included in the study. Patients with a history of previous hip surgery, radiologic evidence of advanced osteoarthritis (Tönnis grade > 2), who underwent labral resection, or whose digital recordings were incomplete or of insufficient quality for adequate review were excluded. Two orthopedic surgeons, who did not participate in the surgery, independently reviewed the video recordings and classified the remaining acetabular cartilage using the post-treatment classification system. Intraobserver and interobserver analysis was then conducted using intraclass correlation coefficient (ICC).
Results Excellent intraobserver reliability (ICC = 0.790; p < 0.001) and interobserver reliability (ICC = 0.882; p < 0.001) were observed. Both ICC values were statistically significant.
Conclusion The posttreatment classification of the remaining acetabular cartilage has excellent intra and interobserver reliability.
