Hip Injuries in Kicking Athletes

Hip Pain Increases With Age and Experience Level in Adult Karate Athletes: A Statewide Survey Study

Purpose

To investigate the prevalence of hip pain from labral tears and femoroacetabular impingement (FAI) in karate athletes using a statewide online survey.

Methods

An anonymous electronic survey was distributed via Qualtrics to all registered members of a statewide karate organization who were a purple belt or higher. Basic demographic information was collected as well as belt level, competitive level, and information regarding hip pain and treatment for hip pain. Microsoft Excel was used to store and analyze data.

Results

Of 180 respondents, 123 (68.3%) never had hip pain when practicing karate, and 54 (30.0%) had hip pain at some point in their karate career. Three subjects did not provide an answer and were excluded. Furthermore, of the symptomatic individuals, 52 reported the location of their hip pain, whereas 2 subjects did not. Of the symptomatic individuals (54), 32 had formal diagnoses by a medical professional, 4 (12.5%) were diagnosed with FAI of the hip, 6 (18.8%) diagnosed with a hip labral tear, 3 (9.4%) diagnosed with hip bursitis, 3 (9.4%) diagnosed with hip arthritis, and 16 (50%) had other diagnoses. The remaining 22 participants have not received a formal diagnosis by a medical professional.

Conclusions

The prevalence of hip pain in karate athletes in this survey was lower compared to athletes of other martial arts and kicking sports. No differences in the percentage of injuries were found between sex and years practiced; however a higher incidence of hip pain was found between elite status and age group. When evaluating hip pain in the karate population, orthopaedic surgeons should maintain an index of suspicion for FAI and hip labral tears.

Return to Sport After Femoroacetabular Impingement Surgery and Sport-Specific Considerations: a Comprehensive Review

PURPOSE OF REVIEW

Recent advancements in surgical technology and techniques have improved functional results for operative treatment of femoroacetabular impingement syndrome (FAIS). Few studies have comprehensively evaluated the literature regarding return to sport criteria, timing, level, and rates. The purpose of this study was to review recent studies regarding return to play after surgical correction of FAIS. We will specifically evaluate the level of return to play and look to compare pre- and postoperative competition levels when available. We will also analyze timing of return to play from injury to surgery. Additionally, we will elucidate any sport-specific criteria that may determine readiness for return.

RECENT FINDINGS

Athletes with FAIS treated non-operatively have a low rate of return to sport and are often functionally limited in their level of performance. Surgical management of FAIS includes hip arthroscopy as well as open techniques. Current literature suggests a high rate of return to sport after contemporary surgery for FAIS at 87-93% overall. Rate of return to the same level of competition following surgery for FAIS is 55-83% in pooled studies. Limited evidence is available comparing postoperative rehabilitation protocols and timing of return among different sports. Operative treatment of FAIS results in high rates of return to sport and functional performance. The results of this study may help educate patients preoperatively in regard to the likelihood of functional return to sport and sport-specific considerations. Further research evaluating rehabilitation protocols and return criteria may better elucidate timing intervals for patients to maximize function while limiting complications.
