干预措施:

常规康复治疗遵循最新的增强术后恢复(ERAS)理念[10],以运动疗法为主。治疗内容包括:(1)关节松动技术,采用Maitland手法,根据患者耐受程度选择I~IV级手法,包括髌骨上下左右滑动、胫股关节前后滑动和旋转、屈膝摆动等治疗,每个手法重复10-15次,总时间15 min/次;(2)关节牵伸训练,患者坐于治疗床边缘,患侧大腿置于床沿,小腿自然下垂,治疗师一手固定大腿远端,另一手置于胫骨远端,缓慢施力促进膝关节屈曲,至患者感觉牵拉但可耐受为止,维持30秒为1组,组间休息30秒,共5组/次;(3)肌力训练,包括股四头肌等长收缩(患者仰卧位,膝下垫软枕,用力下压并保持5秒,10次/组,3组)、直腿抬高(仰卧位,伸直膝关节抬高至30°,保持5秒,10次/组,3组)、臀桥训练(仰卧位,双膝屈曲90°,抬起臀部,保持5秒,10次/组,3组)、站立位提踵(扶墙站立,提踵保持3秒,15次/组,3组);(4)功能训练,包括坐站转移、步态训练、平衡训练等,15 min/次。上述治疗1次/天,5次/周,共2周,每次治疗总时长约60分钟。

干预措施代码:

Intervention:

Conventional rehabilitation treatment follows the latest Enhanced Recovery After Surgery (ERAS) concept [10], focusing primarily on exercise therapy. The treatment content includes: (1) Joint mobilization techniques using the Maitland method, with techniques chosen from grade I to IV based on patient tolerance, including upward, downward, left, and right patellar glides, anterior-posterior glide and rotation of the tibiofemoral joint, knee flexion swings, among others; each technique is repeated 10-15 times, with a total duration of 15 minutes per session; (2) Joint stretching exercises, where the patient sits at the edge of the treatment bed with the affected thigh on the bed edge and the lower leg naturally hanging down, the therapist stabilizes the distal thigh with one hand and places the other hand on the distal tibia to apply slow force to promote knee flexion until the patient feels a tolerable stretch, maintaining for 30 seconds per set, with a 30-second rest between sets, totaling 5 sets per session; (3) Muscle strength training, including quadriceps isometric contraction (patient in supine position with a soft pillow under the knee, press down with force and hold for 5 seconds, 10 repetitions per set, 3 sets), straight leg raises (supine, raise straightened leg to 30°, hold for 5 seconds, 10 repetitions per set, 3 sets), glute bridges (supine, knees bent at 90°, lift hips, hold for 5 seconds, 10 repetitions per set, 3 sets), and standing calf raises (standing against wall, raise heels and hold for 3 seconds, 15 repetitions per set, 3 sets); (4) Functional training, including sit-to-stand transitions, gait training, and balance training for 15 minutes per session. The above treatments are administered once daily, 5 times a week, for 2 weeks, with each session lasting approximately 60 minutes.

干预措施:

采用Swiss DolorClastSmart(EMS公司,瑞士)冲击波治疗仪。治疗参数设置为:压力0.20-0.30 MPa,频率10 Hz,脉冲数2000次/次,治疗间隔为每周2次,间隔2-3 d。治疗靶点包括:(1)大腿前侧股直肌肌腱(髌骨上缘向上5-10 cm处);(2)髌上囊(髌骨上缘处);(3)髌韧带(髌骨下缘至胫骨结节);(4)大腿后侧腘绳肌腱(腘窝处)。每个靶点500次冲击,共2000次。治疗时患者取舒适体位,在靶点涂抹耦合剂,探头垂直于皮肤表面,根据患者耐受调整压力。治疗结束后立即冰敷10 min,以减轻局部微血管反应。ESW治疗2次/周,共2周(总计4次)。

干预措施代码:

Intervention:

Using the Swiss DolorClastSmart (EMS, Switzerland) shockwave therapy device. The treatment parameters were set as follows: pressure 0.20-0.30 MPa, frequency 10 Hz, 2000 pulses per session, with treatments twice a week, spaced 2-3 days apart. Treatment targets included: (1) the rectus femoris tendon on the front of the thigh (5-10 cm above the superior edge of the patella); (2) the suprapatellar bursa (at the superior edge of the patella); (3) the patellar ligament (from the inferior edge of the patella to the tibial tuberosity); (4) the hamstring tendons on the back of the thigh (in the popliteal fossa). Each target received 500 pulses, totaling 2000 pulses. During treatment, the patient was positioned comfortably, coupling gel was applied to the target area, the probe was held perpendicular to the skin surface, and pressure was adjusted according to the patient's tolerance. After treatment, ice was applied for 10 minutes to reduce local microvascular reactions. ESW treatment was administered twice a week for 2 weeks (a total of 4 sessions).
