Percutaneous periarticular multi-drug injection at one day after total knee arthroplasty as a component of multimodal pain management: a randomized control trial

Table 4 Mean number of suppositories used as rescue analgesia

Duration after surgery	Additional periarticular injection (21 patients)	No additional injection (20 patients)
On the night of surgery	0.05 ± 0.22	0.10 ± 0.31
Postoperative day 1	0.10 ± 0.30	0.30 ± 0.57
Postoperative day 2	0.19 ± 0.40	0.10 ± 0.31
Postoperative day 3	0.14 ± 0.36	0.15 ± 0.49
Postoperative day 4	0.05 ± 0.22	0
Postoperative day 5	0	0.10 ± 0.45

Repeated measures analysis of variance showed that the additional periarticular injection was not associated with the difference of the number of suppositories used as rescue analgesia VAS at rest (p = 0.55)
