Résumé
Contracture of the gastrocnemius has been associated with different foot and ankle pathologies. The present study's aim is to evaluate the effect of the proximal medial gastrocnemius release (PMGR) in triceps surae strength. Prospective study with 14 patients (12 women; mean age 52 years). Inclusion criteria were patients undergoing PMGR due to forefoot and/or hindfoot injury with medial gastrocnemius contracture that has not improved with physical therapy. Isometric and isokinetic force evaluation tests with an isokinetic dynamometer (Con-Trex) were performed preoperatively, at 6 and 12 months postoperative, of both limbs. After isokinetic assessment, the statistically significant difference in the preoperative isometric strength of the triceps between the two ankles was confirmed, being stronger the asymptomatic limb. An improvement in the triceps strength in isokinetics was observed at 60°/s at 6 months after surgery (p=0.008), that was maintained after one year (p=0.05). No differences were observed at 120°/sec speed. Patients with gastrocnemius contracture present a decrease in isometric force with respect to the asymptomatic limb preoperatively. There is an improvement in isokinetic strength after 6 months postoperatively.

BACKGROUND
BACKGROUND
Contracture of the gastrocnemius has been associated with different foot and ankle pathologies. The present study's aim is to evaluate the effect of the proximal medial gastrocnemius release (PMGR) in triceps surae strength.
METHODS
METHODS
Prospective study with 14 patients (12 women; mean age 52 years). Inclusion criteria were patients undergoing PMGR due to forefoot and/or hindfoot injury with medial gastrocnemius contracture that has not improved with physical therapy. Isometric and isokinetic force evaluation tests with an isokinetic dynamometer (Con-Trex) were performed preoperatively, at 6 and 12 months postoperative, of both limbs.
RESULTS
RESULTS
After isokinetic assessment, the statistically significant difference in the preoperative isometric strength of the triceps between the two ankles was confirmed, being stronger the asymptomatic limb. An improvement in the triceps strength in isokinetics was observed at 60°/s at 6 months after surgery (p=0.008), that was maintained after one year (p=0.05). No differences were observed at 120°/sec speed.
CONCLUSION
CONCLUSIONS
Patients with gastrocnemius contracture present a decrease in isometric force with respect to the asymptomatic limb preoperatively. There is an improvement in isokinetic strength after 6 months postoperatively.
