Effects of platelet-rich plasma injection therapy combined with muscle strength training on ankle function in patients with traumatic ankle arthritis / 中国基层医药

Objective:To investigate the effects of platelet-rich plasma injection therapy combined with muscle strength training on ankle function in patients with traumatic ankle arthritis.Methods:The clinical data of 98 patients with traumatic ankle arthritis admitted to The 906 Hospital of PLA Joint Logistics Support Force from January 2020 to January 2021 were retrospectively analyzed. These patients were grouped according to different treatment methods. Patients in the control group ( n = 31) received muscle strength training. Patients in the sodium hyaluronate group ( n = 33) received muscle strength training and intraarticular injection of sodium hyaluronate. Patients in the platelet-rich plasma group ( n = 34) received muscle strength training and intraarticular injection of platelet-rich plasma. Ankle function, excellent and good recovery rate, and muscle strength were compared among the three groups before and after treatment. Results:After treatment, the American Orthopaedic Foot & Ankle Society scores in the control, sodium hyaluronate, and platelet-rich plasma groups were (38.22 ± 3.02) points, (41.55 ± 2.04) points, and (44.22 ± 2.69) points respectively, pain scores were (26.98 ± 4.05) points, (31.22 ± 4.20) points, and (34.44 ± 2.44) points respectively, on-line scores were (6.11 ± 1.41) points, (7.39 ± 1.06) points, and (8.25 ± 1.03) points respectively. There were significant differences in the American Orthopaedic Foot & Ankle Society scores, pain scores, and online scores among the three groups ( F = 43.01, 34.30, 27.21, all P < 0.001). In the control, sodium hyaluronate, and platelet-rich plasma groups, dorsiflexor strength was (103.66 ± 10.69) N·m, (129.33 ± 12.37) N·m, (133.69 ± 10.58) N·m, respectively, plantar flexor strength was (121.36 ± 15.69) N·m, (140.23 ± 14.66) N·m, (144.55±13.55) N·m, respectively, ankle function score was (84.22 ± 2.69) points, (88.55 ± 3.01) points, (92.56 ± 3.55) points, respectively. There were significant differences in dorsiflexor strength, plantar flexor strength, and ankle function score among the three groups ( F = 66.37, 22.70, 58.05, all P < 0.001). There was no difference in adverse reactions among the three groups ( Z = 1.05, P > 0.05). Conclusion:Platelet-rich plasma injection therapy combined with muscle strength training is highly effective on traumatic ankle arthritis and can markedly improve ankle function and prognosis.
