Pulsed radiofrequency of iPACK (interspace between the popliteal artery and the posterior knee capsule) for pain control following meniscus repair - A case report.

Adequate postoperative pain control is an essential factor for the success of rehabilitation programs after meniscus repair (MR). The pulsed radiofrequency of the interspace between the popliteal artery and the posterior knee capsule (PRF-iPACK) is a recently developed method. This study aimed to evaluate the use of PRF-iPACK in patients who underwent MR. We performed PRF-iPACK guided by ultrasonography for patients who underwent MR with aggravated pain. PRF-iPACK was performed following MR four weeks after surgery. The pain was evaluated using the visual analogue scale (VAS), Lysholm score, and the Euroqol-5 Dimension (EQ-5D). In this study, two patients participated. For the results, a week and three months after treatment, the mean VAS score, Lysholm score, and EQ5D improved from 7 to 1 and 0 respectively, and 42 to 86 and 90 respectively, and 0.48 to 0.82 and 0.92 respectively. We concluded that PRF-iPACK is an adequate and safe procedure for managing postoperative pain after MR. It may enhance the postoperative rehabilitation program.
