Progressive Muscle Relaxation Training (PMRT) involves a series of 11 steps, each involving muscle tension for 10 seconds, followed by 5 seconds of relaxation, with each step repeated twice. This method, provided by the Chinese Medical Association Audiovisual Publishing House, starts on the third postoperative day if there are no complications, with two 30-minute sessions daily. After PMRT, patients proceed with an Acupressure protocol. The session begins with 5-10 minutes of kneading around the knee and pinching the quadriceps, followed by lighter kneading around the patella and its periphery. Knee movements are made within pain limits. Acupressure targets points Zusanli(S36), Sanyinjiao (SP6), and Yanglingquan(GB34) with pressure held for 10 seconds when soreness or numbness is felt. Each point is treated in 3-5 cycles during the twice-daily, 5-minute sessions, concluding with palm percussion on the calf to relax muscles.

Following recommended protocols from "Arthroscopic Surgery and Sports Rehabilitation Nursing" 26, post-meniscectomy patient care primarily involves vital sign monitoring, positional support, dietary management, pain control, psychological support, functional training, and educational initiatives on health matters.

Progressive Muscle Relaxation Training (PMRT) is a structured strategy created to reduce psychological and physiological stress by alternating muscle contraction and relaxation.Rooted in traditional Chinese medicine's meridian theory, acupressure employs manipulative techniques on distinct acupoints to induce therapeutic effects 18. Targeting enhanced circulation, pain relief, muscle relaxation, and systemic regulation, acupressure's efficacy as both a preventive and therapeutic modality in complementary and alternative medicine is well-established

The Tampa Scale for Kinesiophobia (TSK) The TSK assesses fear of movement/(re)injury and ranges from 17 to 68, indicating the degree of fear; higher scores denote increased apprehension. It has a Cronbach's alpha of 0.70-0.92 and a test-retest reliability above 0.80 28, 29. The Chinese version of TSK was cross-culturally adapted and validated by Wei et al.displaying good reliability (Cronbach's alpha: 0.74) and validity (test-retest reliability: 0.86).

Visual Analogue Scale（VAS） Pain levels were quantified using VAS, which rates pain intensity on a 100 mm line ranging from 0 (no pain) to 10 (severe pain). The VAS is widely deemed a credible and efficacious pain rating tool 31.

American knee society score（KSS ） The KSS scores knee functionality in two domains: self-reported symptoms, signs, and a functional component reflecting walking and stair climbing abilities. Higher scores represent more optimal knee function and mobility capacities. Each KSS domain is rated from 0 to 100 and can be considered individually or collectively.
