A Pretest post-test control group design will be used to investigate the effect of kinesio taping on electrical activity and peak torque of the quadriceps femoris muscle during concentric and eccentric contraction after arthroscopic partial meniscectomy (APM) surgery.

Fifty patients after APM of any knee of both sexes will participate in this study after signing a written informed consent form approved.

from the ethical committee of Jazan University. They are selected according to the following Inclusion criteria:

1. All performed APM only without any other knee injury.
2. Finished the period of hospital stay (6-8 weeks)
3. Their age ranged from 20-40.
4. Their Body mass index ranged from 20-24.9 kg/m². 2- The subjects will be excluded from the study if they had one of th e following exclusion criteria: a- Knee or quadriceps disorders preventing physical stress. b- Subjects with cardiovascular or neurological problems. c- Smokers. d- Heavy caffeine intake subjects. 3- The subjects will be randomly assigned into two groups of equal numbers. Group A (Study) consisted of 66 subjects who will receive kinesio-taping from origin to insertion on the superficial muscles of the Quadriceps femoris (QF) (Vastus Medialis (VM), Vastus Lateralis (VL), Rectus Femoris (RF)). - Group B (Control) consisted of 66 subjects who will receive a placebo kinesio-taping across quadriceps. Anthropometric measures including "weight and height" and body. mass index (BMI) will be measured for all subjects in the first meeting before starting the evaluative procedures. All subjects were asked to shave the hair of their thigh before starting the evaluative procedure using blades, which was essential to prevent artifact during EMG evaluation and to facilitate the adherence of the tape to the skin. Bioelectrical activity and peak torque of quadriceps muscle of the lower extremity that had APM will be measured. The evaluation will be carried out before tapping, and then after the application of tapping for 10 minutes.

Inclusion Criteria:

1. Clinical diagnosis only with arthroscopic partial meniscectomy
2. Must be finished a period of hospital stay (6-8 weeks)
3. Must have body mass index ranged from 20-24.9 kg/m².

Exclusion Criteria:

a. Knee or quadriceps disorders preventing physical stress. b- Cardiovascular or neurological problems. c- Smokers d- Heavy caffeine intake subjects.

I will share the data on request.
