Abstract
Background and Aims From 8% to 44% of patients after knee arthroplasty experience pain of varying severity (Qudsi-Sinclair S. et al., 2016; Hagedorn JM et al., 2020), which prevents successful rehabilitation. Interventional techniques are most effective in the treatment of pain of various origins, however, there is not enough information about their use after knee arthroplasty. The aim of the study was to evaluate the analgesic efficacy of N. saphenus blockade at the 2nd inpatient stage of medical rehabilitation after knee arthroplasty.
Methods The study included 12 patients who underwent rehabilitation after knee arthroplasty at stage 2 in the inpatient medical rehabilitation department. Inclusion criteria – pain syndrome 5-6 points according to the CRS at rest, 7-8 points during movement. Patients were randomly divided into 2 groups. In group I (n=6), rehabilitation measures were carried out without the use of therapeutic and diagnostic blockades. In group II (n=6), rehabilitation was supplemented by N. saphenus blockade on days 7-8 after joint arthroplasty. Blockades were performed using local anesthetic solutions and glucocorticosteroids with online ultrasound navigation. The criterion of effectiveness of rehabilitation measures is the Knee Society Score.
Results The use of N. saphenus blockade has a positive effect on the range of motion in the knee joint and the ability to walk up the stairs due to a significant decrease in the intensity of the pain.
Conclusions The study showed the high efficiency of therapeutic and diagnostic blockades of N. saphenus to increase the effectiveness of rehabilitation measures after arthroplasty at the 2nd inpatient stage of rehabilitation.
