Abstract
Background:
The rate of return to sport after surgical treatment of femoroacetabular
impingement (FAI) syndrome (FAIS) has been studied in high-level athletes.
However, few studies examining this rate have focused exclusively on
National Collegiate Athletic Association (NCAA) Division I athletes.
Purpose:
To evaluate the return-to-sport rate after hip arthroscopy for FAIS and to
examine the influence of sport type on the clinical presentation of FAIS in
collegiate athletes.
Study Design:
Case series; Level of evidence, 4.
Methods:
Included in this study were NCAA Division I student-athletes who underwent
hip arthroscopy for FAIS at our institution between 2010 and 2017. Exclusion
criteria were history of previous hip pathology, pediatric hip disease,
radiographic evidence of osteoarthritis (Tönnis grade >0), prior lower
extremity procedure, history of chronic pain, osteoporosis, or history of
systemic inflammatory disease. Athletes were categorized into 6 subgroups
based on the type of sport (cutting, contact, endurance, impingement,
asymmetric/overhead, and flexibility) by using a previously reported
classification system. Patient characteristics and preoperative,
intraoperative, and return-to-sport variables were compared among sport
types.
Results:
A total of 49 hip arthroscopies for FAIS were performed in 39 collegiate
athletes (10 females, 29 males; mean age, 19.5 ± 1.3 years). A total of 1
(2.6%) cutting athlete, 15 (38.5%) contact athletes, 8 (20.5%) impingement
athletes, 6 (15.4%) asymmetric/overhead athletes, and 9 (23.1%) endurance
athletes were included in the study. There were no differences among sports
groups with respect to the FAI type. Endurance athletes had lower rates of
femoral osteochondroplasty (45.5%) and labral debridement (0.0%)
(P < .0001). Contact sport athletes had higher rates
of labral debridement (50.0%; P < .0001). Patients were
evaluated for return to sport at an average of 1.96 ± 0.94 years. Overall,
the return-to-sport rate was 89.7%. There were no differences in
return-to-sport rates based on the sport type except for endurance athletes,
who returned at a lower rate (66.6%; P < .001). No
differences in return-to-sport rate (P = .411), duration
after return (P = .265), or highest attempted level of
sport resumed (P = .625) were found between patients who
underwent labral repair versus debridement.
Conclusion:
Collegiate-level athletes who underwent hip arthroscopy for FAIS returned to
sport at high and predictable rates, with endurance athletes possibly
returning to sport at lower rates than all other sport types. Surgical
procedures may be influenced by sport type, but the rate of return to sport
between athletes who underwent labral debridement versus labral repair was
similar.
