Background The knee is one of the joints in the human body that is most susceptible of osteoarthritis (OA). In the case of advanced-stage OA, total knee arthroplasty (TKA) is a treatment of choice. One modern physiotherapeutic method to support the treatment in the early postsurgical period is Kinesio Taping (KT). The aim of this study is to evaluate the efficacy of KT on swollen subcutaneous tissue after TKA. Materials and methods. The studied group consisted of 23 patients who had received TKA. The mean BMI was 30.60 ± 4.91, and KT was applied between the 3rd and 8th day of the early postoperative period. The control group was constituted by 22 patients who had received TKA. The mean BMI was 30.41 ± 6.00, and KT was not applied. On the 3rd and 8th day after TKA, in all patients, the swelling of the shin, range of motions (ROM), and pain were measured using ultrasound, a goniometer, and a VAS scale, respectively. Results. In the KT group, the lateral measurement at the top of the head of the fibula significantly decreased between the 3rd and 8th day (11.47 ± 0.76 vs. 9.76 ± 0.77; p = 0.0004). The knee flexion angle on day 3 was statistically significantly different from that on day 8 (48.61 ± 3.08 vs. 72.74 ± 3.92; p = 0.00004). The evaluation results for severity of pain using the VAS scale on day 3 were statistically significantly higher than those on day 8 (5.74 ± 0.25 vs. 4.30 ± 0.25; p = 0.00006). In the group of patients to whom KT was not applied, the lateral measurement at the top of the head of the fibula on day 3 was not statistically significantly different from that on day 8 (10.323 ± 0.828 vs. 10.273 ± 0.995; p = 0.9227). The knee flexion angle in the group that did not receive KT on day 3 was statistically significantly different from that on day 8 (45.182 ± 3.654 vs. 59.909 ± 4.817; p = 0.0006). The severity of pain evaluated using the VAS scale on day 3 was statistically significantly different from that on day 8 (6.227 ± 0.146 vs. 4.864 ± 0.190; p = 0.0001). Conclusions. KT is an effective method for improving subcutaneous drainage and decreasing subcutaneous tissue. However, KT does not affect postoperative pain and ROM.

The aim of the study was to evaluate the levels of selected MMPs (matrix metalloproteinases) and osteocalcin in the serum and synovial fluid of obese women with osteoarthritis and their correlations with clinical status. The studied group consisted of 39 overweight females undergoing primary total knee arthroplasty due to osteoarthritis (OA). The staging of knee OA was evaluated according to the Ahlbӓck and Kellgren–Lawrence scores. Synovial fluid and peripheral blood samples were obtained. The levels of selected MMPs and osteocalcin were assessed using commercial ELISA kits. The mean value of MMP3 was significantly higher in patients with more advanced disease in both serum (p = 0.0067) and synovial fluid (p = 0.0328). The pro-MMP13 level tended to be higher in synovial fluid in the case of more advanced stages (p = 0.0882), with no tendency regarding the serum level (p = 0.9595). The synovial level of pro-MMP1 was significantly correlated with the synovial concentration of MMP9 and MMP3. The synovial level of MMP9 also showed a significant correlation with the synovial level of MMP3 and pro-MMP13. Furthermore, it was found that the serum level of MMP3 was significantly correlated with the synovial pro-MMP13 level. A correlation between the osteocalcin level in serum and its synovial level was determined. The serum MMP9 level showed a significant correlation with BMI, whereas the synovial MMP9 level was notably correlated with age. Our results showed that the levels of MMP3, MMP9, and pro-MMP13 increased in more advanced radiological stages of OA, indicating the underlying inflammatory process of OA.

The aim of this study was to assess levels of adiponectin (ACRP-30) and leptin in serum and synovial fluid (SF) of overweight females with primary gonarthrosis (GOA) and to look for their correlations with clinical status and the level of biochemical OA biomarkers: matrix metalloproteinase (MMP) 1, MMP-9 and tissue inhibitor of metalloproteinase (TIMP-1). The studied group consisted of 39 overweight females undergoing primary total knee arthroplasty as a result of GOA. The stage of GOA was evaluated according to Knee Society Score (KSS), Ahlbäck and Kellgren–Lawrence (K-L) scores. Peripheral blood and SF were obtained. Levels of selected biomarkers were assessed using ELISA kits. The mean level of ACRP-30 in serum valued were 8393.80 ng/mL and in SF, 774.33 ng/mL, the mean concentration of leptin in serum was 32,040.74 pg/mL and in SF, 27,332.12 pg/mL. Levels of leptin in serum and SF correlated with body mass index (BMI), (p = 0.0005, and p = 0.0002, respectively). Levels of ACRP-30 in serum was correlated with clinical scores (Ahlbäck: p = 0.0214; K-L: p = 0.0146). ACRP-30 in SF correlated with ACRP-30 in serum (p = 0.0003), tended to negatively correlate with MMP-1 in serum (p = 0.0598) and positively correlate with pro-MMP-1 in SF (p = 0.0600). To conclude, this study confirms the correlations between concentrations of both, leptin and ACRP-30, comparing serum and SF. In overweight females, leptin levels increase with BMI and ACRP-30 serum level increase in more advanced GOA stages. Finally, leptin levels were correlated with TIMP-1 serum concentration, one of the biochemical markers of GOA.
