Recovery patterns in patients undergoing revision surgery of the primary knee prosthesis

Journal of Experimental Orthopaedics

Table 4 Range of motion values in recovery trajectory groups

	No improvement n = 15	Short improvement n = 20	Late improvement n = 12	Prolonged improvement n = 41
RoM preoperative	105 (45–140)	120 (50–140)	120 (75–140)	115 (65–140)
RoM 3 months postoperative	115 (50–140)^a	120 (85–130)^b	115 (95–130)	120 (100–130)^a
RoM 12 months postoperative	110 (50–130)^c	120 (40–135)^b	120 (105–135)^a	120 (100–135)^a*

Note: presented as median (min-max). RoM range of motion; ^a, 1 missing value; ^b, 2 missing values; ^c, 3 missing values; ^*, indicates significant improvement preoperative versus twelve months postoperative (p < 0.05)
