Functional training after total knee arthroplasty (TKA) is of great significance for the recovery of knee function. However, the utility of applying an effective training modality, closed-chain isokinetic plyometric training, on top of the drug palonosetron, which is used to prevent nausea and vomiting, is unclear.
To investigate the effect of closed-chain isokinetic plyometric training combined with palonosetron-on-postoperative-knee-function in patients with TKA, aiming to provide an effective rehabilitation program for patients with TKA.
The results of the intervention were compared in 47 TKA patients who received closed-chain isokinetic plyometric training combined with palonosetron with 47 TKA patients who received conventional plyometric training combined with palonosetron. Knee function was evaluated using the Hospital for Specialty Surgery Knee (HSS), quadriceps muscle strength was assessed using real-time isometric plyometric testing with the BIODEX-sYs-tem 4-type system, walking ability was evaluated using the Timed Up-and-Go Test (TUGT), and proprioception was determined using the Biodex System 4-type multi-joint isometric system.
After-the intervention,-the-HSS scores-of-the-experimental-group-were-higher-than-those-of-the-control-group-( < 0.05); the peak moment values of the quadriceps (PT), the total quadriceps work values (STW), and the average power of the quadriceps (AP) were higher than those of the control group ( < 0.05); and the values of the reproduced deviation of the knee joint active joint angle and the TUGT time were lower than those of the control group ( < 0.05).
Closed-chain isokinetic plyometric training combined with palonosetron can strengthen their muscle strength and improve proprioception, which effectively promotes the recovery of postoperative knee function and walking ability in TKA patients.
全膝关节置换术（TKA）后进行功能训练对膝关节功能恢复具有重要意义。然而，在用于预防恶心和呕吐的药物帕洛诺司琼基础上，应用一种有效的训练方式——闭链等速增强式训练的效用尚不清楚。
探讨闭链等速增强式训练联合帕洛诺司琼对TKA患者术后膝关节功能的影响，旨在为TKA患者提供有效的康复方案。
将47例接受闭链等速增强式训练联合帕洛诺司琼的TKA患者与47例接受传统增强式训练联合帕洛诺司琼的TKA患者的干预结果进行比较。使用特种外科医院膝关节评分（HSS）评估膝关节功能，使用BIODEX系统4型系统通过实时等长增强式测试评估股四头肌力量，使用定时起立行走测试（TUGT）评估步行能力，使用Biodex系统4型多关节等长系统测定本体感觉。
干预后，实验组的HSS评分高于对照组（<0.05）；股四头肌的峰值力矩值（PT）、股四头肌总做功值（STW）和股四头肌平均功率（AP）高于对照组（<0.05）；膝关节主动关节角度再现偏差值和TUGT时间低于对照组（<0.05）。
闭链等速增强式训练联合帕洛诺司琼可增强肌肉力量，改善本体感觉，有效促进TKA患者术后膝关节功能和步行能力的恢复。
