      Symptoms or Previous Injuries, Independent of Cam Deformities.

AB  - BACKGROUND: Soccer (football) players often have hip and groin symptoms (HGS), 
      and a previous groin injury is a risk factor for a relapse. Decreased hip range 
      of motion (HROM) has been related to both hip and groin pain and the presence of 
      a cam deformity. How these factors interact is unknown. PURPOSE: The first aim 
      was to study whether HGS are associated with HROM. The second aim was to study 
      the association of the presence of a cam deformity with HROM. Additionally, the 
      influence of a cam deformity on the relationship between HGS and HROM was 
      examined. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: 
      Seasonal screening data of 2 professional soccer clubs were used. Variables for 
      HGS were current hip or groin pain, the Copenhagen Hip and Groin Outcome Score 
      (HAGOS), and previous hip- and groin-related time-loss injuries (HGTIs). HROM was 
      determined for hip internal rotation (IR), external rotation, and total rotation 
      (TR) in the supine position and for the bent knee fall out (BKFO) test. A cam 
      deformity was defined by an alpha angle >60 degrees  on standardized anteroposterior 
      pelvic and frog-leg lateral radiographs. RESULTS: Sixty players (mean [+/-SD] age, 
      23.1 +/- 4.2 years) were included. All were noninjured at the time of screening. 
      Current hip or groin pain was not associated with HROM. Hips of players in the 
      lowest HAGOS interquartile range (thus most affected by complaints; n = 12) 
      showed less IR (23.9 degrees  +/- 8.7 degrees  vs 28.9 degrees  +/- 7.8 degrees , respectively; P = .036) and TR 
      (58.2 degrees  +/- 13.5 degrees  vs 65.6 degrees  +/- 11.8 degrees , respectively; P = .047) than those in the 
      highest interquartile range (n = 29). No such differences were found for BKFO (P 
      = .417). Hips of players with a previous HGTI showed less IR (21.1 degrees  +/- 6.8 degrees  vs 
      28.3 degrees  +/- 8.9 degrees , respectively; P < .001) and TR (56.0 degrees  +/- 8.2 degrees  vs 64.5 degrees  +/- 13.6 degrees , 
      respectively; P < .001) than those without a previous HGTI. This was independent 
      of the presence of a cam deformity. BKFO did not differ between groups (P = 
      .983). Hips with a cam deformity showed less but nonsignificant IR (25.5 degrees  +/- 10.3 degrees  
      vs 29.0 degrees  +/- 7.1 degrees , respectively; P = .066) and TR (P = .062) and higher but 
      nonsignificant BKFO values (17.1 cm +/- 3.4 cm vs 14.2 cm +/- 4.6 cm, respectively; P 
      = .078) than those without a cam deformity. CONCLUSION: Decreased HROM in 
      professional soccer players is associated with more hip- and groin-related 
      symptoms and with previous injuries, independent of the presence of a cam 
      deformity.
