Chronic And Recurrent Rectus Femoris Central Tendon Ruptures In Athletes: Clinical Picture, Mri Findings, And Results Of Surgical Treatment

Background:Severe rectus femoris central tendon rupture is an uncommon sports-related injury. Most rectus femoris central tendon injuries can be treated by nonoperative means, but some tend to reinjure, resulting in chronic symptoms. Physicians treating athletes with rectus femoris injuries should be aware of this clinical condition and know that surgical treatment could be beneficial to the athlete if the rectus femoris central tendon rupture becomes chronic.Purpose:To describe the clinical picture, magnetic resonance imaging (MRI) findings, and surgical treatment results of rectus femoris central tendon injuries.Study Design:Case series; Level of evidence, 4.Methods:This study included 12 patients who underwent successful repair of recurrent rectus femoris central tendon rupture. Presurgical MRI scans were obtained and compared with the surgical findings. The time of return to play was recorded, and the outcome of surgical treatment was evaluated with validated Subjective Patient Outcome for Return to Sports (SPORTS) criteria: good = full return to preinjury level of sports without any symptoms; moderate = return to preinjury level of sports with some residual symptoms (mild discomfort during sports); and poor = did not return to preinjury level of sports.Results:Overall, 10 patients had a good outcome (83%), and 2 had a moderate outcome (17%). All athletes included in the study were able to return to sport at their preinjury levels 2.5 to 4 months postoperatively. Presurgical MRI scans correlated well with the surgical findings.Conclusion:The surgical treatment of rectus femoris central tendon rupture seems to be a good option in chronic and recurrent cases. After surgery and successful rehabilitation, the athlete is expected to continue sports at the preinjury level.
