Femoro Acetabular Impingement Clinical Trial
Official title:
The Effect of Lower Limb Rotation on Clinical Outcomes After Arthroscopic Management in Patients With Symptomatic Femoroacetabular Impingement Syndrome
To determine - The prevalence of abnormalities of femoral and acetabular versions and tibial torsion in symptomatic (FAI) Syndrome. - Analyse the subgroups of specific hip pathomorphologies associated with rotational abnormalities of lower limb (LL). - Which specific hip subtypes of (FAI) are associated with rotational abnormalities, - Outcomes of arthroscopic treatment of (FAI) syndrome in patients with rotational abnormalities compared with a control group of patients with normal rotation.

Primary | 2 years outcome of arthroscopic treatment of 50 patients with FAI syndrome using modified Harris Hip Score (mHHS). | determine Outcomes of arthroscopic treatment of FAI syndrome in patients with rotational abnormalities compared with patients with normal rotation.
normal rotation according to preoperative CT rotational profile: Acetabular version angle between 10° to 25°. Femoral version angle between 10° to 25°. Tibial torsion angle between 25° to 40°. clinical outcome of arthroscopic treatment of patients with FAI syndrome using modified Harris Hip Score (mHHS) will be done preoperatively and postoperatively at 1.5 months, 3 months, 6 months, 1 year, and 2 years. The modified Harris hip score (mHHS) will be scored from 0 (worst functional outcome and maximum pain) to 100 points (best functional outcome and least pain) |

Primary | 2 years outcome of arthroscopic treatment of 50 patients with FAI syndrome using Nonarthritic Hip Score (NAHS). | determine Outcomes of arthroscopic treatment of FAI syndrome in patients with rotational abnormalities compared with patients with normal rotation.
normal rotation according to preoperative CT rotational profile: Acetabular version angle between 10° to 25°. Femoral version angle between 10° to 25°. Tibial torsion angle between 25° to 40°. clinical outcome of arthroscopic treatment of patients with FAI syndrome using Nonarthritic Hip Score (NAHS) will be done preoperatively and postoperatively at 1.5 months, 3 months, 6 months, 1 year, and 2 years. This score is divided into four domains: pain, mechanical symptoms, physical function, and level of activity. The maximum score is 100 indicating normal hip function. |

Primary | 2 years outcome of arthroscopic treatment of 50 patients with FAI syndrome using Hip Outcome Score-Sports Specific Subscale (HOS-SSS) | determine Outcomes of arthroscopic treatment of FAI syndrome in patients with rotational abnormalities compared with patients with normal rotation.
normal rotation according to preoperative CT rotational profile: Acetabular version angle between 10° to 25°. Femoral version angle between 10° to 25°. Tibial torsion angle between 25° to 40°. clinical outcome of arthroscopic treatment of patients with FAI syndrome using Hip Outcome Score-Sports Specific Subscale (HOS-SSS) will be done preoperatively and postoperatively at 1.5 months, 3 months, 6 months, 1 year, and 2 years. The (HOS-SSS) is a patient-completed measure that consists of "(9 scored items) in which the response options are presented as 5-point Likert scales. Scores for each subscale range from 0% (least function) to 100% (most function). |
