Outcome and Prognostic Factors of Achilles Rupture Repair Using a New Scoring Method

A new clinical scoring system, including subjective assessment of symptoms and evaluation of ankle range of motion and isokinetic measurement of ankle plantar flexion and dorsiflexion strengths, is presented in 101 patients (86 men, 15 women) who had repair of a closed Achilles tendon rupture. Twenty-one patients were competitive athletes and 70 were recreational athletes. Eighty-one percent of the ruptures were related to sports, and 32% occurred while playing volleyball. Twenty-six patients had previous Achilles tendon symptoms. At followup, an average of 3.1 years after repair, the overall result scores were excellent in 34 cases, good in 46, fair in 17, and poor in four. Only age was a predictor of overall results. The isokinetic strength scores were excellent or good in 72 cases, fair in 18, and poor in 11. Presence of systemic diseases, activity level, previous Achilles tendon symptoms, and later return to physical exercise were predictors of strength results. Gender, body weight, height, period between rupture and operation, surgeon, rupture site, operative method, complications, and thickness, width, and area of the Achilles tendon at followup were not related significantly to the outcome.
