“…Different classifications for muscle injuries have been proposed in the literature which are used in clinical settings 4 . Although the rectus femoris muscle strains are common, high grade 4 injuries can be seen especially in soccer where sprinting and kicking require eccentric rectus femoris contraction 6,7 . The avulsions of proximal rectus femoris from the anterior superior iliac spine have been well documented in athletes [8][9][10] .…”

Introduction: Rectus femoris muscle injuries are common in sports. Although majority of these injuries are treated conservatively, some tend to present significant disability which could compromise the returning to pre-activity level of competition in athletes. The purpose of this study is to evaluate possible benefits of operative treatment in acute and recurrent rectus femoris ruptures. Methods: Retrospectively, a total of 27 patients (23 men, 4 women) with grade 4 rectus femoris muscle rupture which located at the diaphyseal area between proximal and distal myotendinous junctions. Operative treatment was carried out in the acute (8 cases, < 4 weeks after injury) or recurrent rectus femoris ruptures (19 cases). Results: 20 (74%) patients had excellent or good results, moderate results in 6 (26 %) and poor (required re-operation after re-injury) in 1 (4%) patients. The return to pre-activity level of competition was 5 months on average. Adverse events were haematoma (n=4, percutaneously drained), superficial infection (n=1, healed with cephalexin antibiotics), partial dehiscence of the wound (n=1, no intervention). Conclusion:Based on these cases, excellent or good results may often be expected after surgical repair of grade 4 rectus femoris midsubstance ruptures. Level of evidence: IV, Case series.

The hamstring muscle group is the most frequently injured muscle group in non-contact muscle injuries in sports involving high-speed running. A total of 84% of hamstring injuries affect the biceps femoris (BF) muscle. Clinical assessments and magnetic resonance imaging (MRI) are routinely used for diagnosis and plan management. MRI-negative scans for clinically diagnosed hamstring injuries range from 14% to 45%. We tested the hypothesis that the functional differences between injured and non-injured BF assessed by tensiomyography can be used for diagnostic and classification purposes. We compared an injured group of 53 international-level soccer players and sprinters with 53 non-injured international-level soccer players and sprinters of both sexes. Comparing the injured vs. non-injured athletes and the left vs. right side in all of the athletes, we used the percentage of absolute differences in the BF contraction time (Tc) to classify non-injured and injured BF muscles. The receiver operating characteristic (ROC) curve and the area under the curve (AUC) and the precision–recall curve (PRC) were used to measure the classification accuracy and to identify cut-off limits using the Tc differences. There was a very high ROC AUC value of 0.981 (SE = 0.009, p < 0.000), with 98.11% of the injured muscles being correctly classified (cut-off point 12.50% on Tc differences), and an AUPRC value of 0.981, with association classification criteria at >9.87. Tensiomyography has a high predictive ability to discriminate between injured and non-injured BF non-invasively and functionally.
