Abstract Background: Early recognition of the clinical signs of ruptures of the pectoralis major muscle (PMM) in athletes by orthopaedic surgeons, physical therapists, and physical trainers may prove to be critical for patient access to surgical treatment while the injury is still in the acute phase.Hypothesis: Total ruptures of the PMM may yield a better outcome with surgical treatment than with nonoperative treatment in athletes.Study Design: Cohort study; Level of evidence, 2.Methods: A prospective study was performed on 60 patients with total ruptures of the PMM. the patients were followed from 1997 to 2012, with a physical examination every 6 months for the first 2 years and every 12 months thereafter. the patients' mean age was 31.21 years, and the mean length of follow-up was 48.25 months. the surgical treatment methods included reinsertion of the tendon in 51% of the patients and nonoperative treatment in 49% of the patients. All of the patients were evaluated using the Bak criteria.Results: the bench-press exercise was associated with 80% of the PMM ruptures (48 patients). Forty-one of the patients with chronic ruptures were seen after 3 months (80%). the outcomes were poor in 9 patients from the nonoperative group (31%) and in 3 patients from the surgical group (9.7%); the outcomes were fair in 12 patients from the nonoperative group and in no patients from the surgical group. Excellent results were not observed in any patient from the nonoperative group and were observed in 21 patients from the surgical group (67.7%). the isokinetic evaluation at 60 deg/s showed a decrease in strength of 41.7% in the nonsurgical group and 14.3% for the surgical group, which was significant at P < .05.Conclusion: Total ruptures of the PMM exhibit better outcomes with surgical treatment than with nonoperative treatment based on the Bak criteria in athletes.
