Early effects of isokinetic muscle strength training on postoperative recovery of patients with Schatzker type Ⅰ-Ⅲ tibial plateau fractures
Objective To explore the efficacy of isokinetic muscle strength training on postoperative recovery of patients with Schatzker type Ⅰ-Ⅲ tibial plateau fractures.Methods The clinical data of 60 patients with Schatzker Ⅰ-Ⅲ tibial plateau fractures admitted to Yantai Affiliated Hospital of Binzhou Medical College from March 2018 to March 2021 were analyzed,including 45 males and 15 females with an average age of(43.8±10.86)years.Grouping by random,30 patients were treated with isokinetic muscle strength training after surgery(isokinetic group),and 30 patients did conventional rehabilitation exercises after surgery(conventional group).The general data,isokinetic peak torque(PT)and total work(TW)evaluation at 6 months after surgery,and Hospital for Special Surgery(HSS)knee function scores at 6 and 12 months after surgery were compared between the two groups.Results The PT of flexor and extensor muscles of the isokinetic group was significantly higher than that of the conventional group[flexor muscles,60°/s:(79.34±7.32)N·m vs.(69.33±7.46)N·m,120°/s:(71.08±6.34)N·m vs.(61.55±9.34)N·m;extensor muscles 60°/s:(160.95±10.13)N·m vs.(148.06±16.96)N·m,120°/s:(136.35±11.21)N·m vs.(125.85±12.59)N·m],and the TW of the isokinetic group was significantly higher than that of the conventional group[flexor muscles,60°/s:(549.51±47.70)J vs.(485.80±49.17)J,120°/s:(439.68±55.42)J vs.(382.38±56.43)J;extensor muscles,60°/s:(965.70±78.09)J vs.(872.69±88.70)J,120°/s:(825.50±70.23)J vs.(730.16±76.01)J],with statistically significant differences(P<0.05).The HSS scores in both groups were significantly improved at 6 months and 12 months after operation(isokinetic group:86.97±6.22 vs.36.89±9.24,96.10±2.99 vs.36.89±9.24;conventional group:70.87±6.61 vs.37.53±9.05,88.40±5.49 vs.37.53±9.05),and the differences were statistically significant(P<0.05).The HSS score of the isokinetic group was significantly better than that of the conventional group at 6 and 12 months after operation(86.97±6.22 vs.70.87±6.61,96.10±2.99 vs.88.40±5.49),with statistically significant differences between the two groups(P<0.05).The number of cases with postoperative complications in the conventional group was 7,much more than 1 case in the isokinetic group.Conclusions Isokinetic muscle strength training benefits the recovery of knee flexor-extensor muscle strength and knee joint function after Schatzker type Ⅰ-Ⅲ tibial plateau fractures.
