Results of arthroscopic treatment of femroacetabular impingement (FAI)

Abstract

Introduction: Femoroacetabular impingement (FAI) has been suggested as an important etiology of pain in the groin region in young adults especially athletes and there are theories connecting it to early onset osteoarthritis. Aim: To assess the results of arthroscopic treatment of FAI. Patients: Forty patients had been managed arthroscopically for their FAI in both El-Hadra university hospital and William Harvey Hospital. Methods: Results of arthroscopic treatment of FAI in 40 consecutive patients had been evaluated using patients reported outcomes (modified Harris Hip Score and international Hip Outcome Tool-12) and clinical measures of improvement of range of motion in both flexion and internal rotation in 90°of hip flexion. Results: The average of the outcome scores showed statistically significant improvement following the arthroscopic intervention. Conclusion: Femroacetabular impingement is an important etiology of groin pain in young adults, nevertheless the athletes. Diagnosis of this condition is primarily a clinical one to be supported with relevant imaging. Hip arthroscopy is an effective approach to treat and correct the underlying bony abnormalities of FAI. Younger age of patients predicts better improvement in i-HOT-12 score.

Hip Range of Motion Is Increased After Hip Arthroscopy for Femoroacetabular Impingement: A Systematic Review

“…Postoperative changes in flexion from each study’s baseline were reported as statistically significant in 57.1% (12/21), not statistically significant in 14.3% (3/21), and statistical significance was not reported in 28.6% (6/21). For those studies reporting statistically significant change in flexion, effect size was weak in 16.7% (2/12) 35 , 36 of studies, moderate in 58.3% (7/123), 27 , 29 , 37 , 38 , 39 , 43 , 45 and large in 25% (3/12) 32 , 34 , 46 of studies. Pre- to postoperative measured changes in flexion for studies evaluating unilaterally operated patients are presented in Figure 2 A, whereas those studies evaluating a mix of unilateral and bilateral patients are presented in Figure 3 A.…”

“…Postoperative changes in IR from each study’s baseline were statistically significant in 74% (17/23), whereas statistical significance was not reported in 26% (6/23). For those studies reporting statistically significant improvements in IR, effect size was moderate in 29.4% (5/17) 27 , 28 , 35 , 36 , 38 of studies, and large in 64.7% (11/17) 30 , 32 , 33 , 34 , 37 , 39 , 43 , 44 , 45 , 46 , 48 of studies. One further study (1/17), 29 evaluating 2 groups of patients, reported a moderate effect size in patients without generalized joint laxity and a large effect size in those with generalized joint laxity.…”

“…The combination of flexion, IR, and ER was exclusively reported in 10 studies 29 , 30 , 31 , 34 , 38 , 39 , 40 , 41 , 42 , 43 and in conjunction with additional measurements in 5 further studies. 25 , 27 , 28 , 32 , 44 Five studies reported flexion and IR only, 37 , 45 , 46 , 47 with 1 further study assessing these measurements in addition to IR at 90° hip flexion with 15° adduction [FADIR]. 36 The remaining 2 studies reported IR only.…”
