Table 6

Mean and standard deviations (in parentheses) of knee and ankle joint angle excursion for the right and left knees and ankles. Knee excursion is defined as knee flexion in swing minus knee flexion in stance. Ankle joint angle excursion is separated by right positive and negative equinus-mediating factor in stance at baseline. Ankle excursion is defined as equinus at toe-off minus equinus in stance.

Excursion	N	Right pre-op	Right post-op	Left pre-op	Left post-op
Knee excursion	17	43.7 (17.3)	47.8 (15.8)	49.4 (20.0)	51.4 (18.2)
Ankle excursion (R positive equinus)	12	18.3 (19.1)	18.4 (13.9)	18.0 (10.7)	9.6 (11.2); Decrease
Ankle excursion (R negative equinus)	5	18.5 (7.6)	15.2 (12.4)	17.9 (21.4)	20.6 (17.3)

The only significant difference: a decrease between pre- and post-test ankle excursion for L ankle, .
