Knee pain is one of common pain-causing diseases and it affects patients' mobility which in turn seriously affects the quality of patients' life. The most common cause of knee pain results from the inflammation occurred at the patello-femoral joint of the anterior knee. It is now commonly recognized as Patello-femoral pain syndrome (PFPS). It is categorized as anterior knee pain. The exact pathogenesis of PFPS is still not clear but both Traditional Chinese Medicine (TCM) and Western Medicine (WM) have many treatment methods. Hence, it is important and meaningful to investigate the diagnosis and treatment in detail. Through reviewing the literature about PFPS, the investigators would like to achieve the following objectives in the study design. Under the principle of evidence-based medicine, the investigators compare the clinical effectiveness of TCM acupuncture and Tui-na manipulations treatment with the physiotherapy on the PFPS management. The study is to determine whether which are effective in improving knee function and lessening the pain in PFPS patients.
The target sample size will be 180 patients approximately, each group namely Traditional Chinese Medicine (TCM)/ Physiotherapy (PT)/ Education group respectively will contain minimum 60 patients respectively. Patients are initially screened with questionnaire implying the PFPS scouring system. Patients will be recruited and firstly screened from Chinese Medicine Practitioner (CMP). Then the secondary screening will be conducted by the WM practitioner in Hong Kong Baptist Hospital (HKBH) to confirm diagnosis and enrollment based on the inclusion and exclusion criteria. X-ray imaging diagnosis and reporting are done in HKBH. The investigators will design a randomized controlled trial, compared with TCM group and PT group. Patients are requested to sign a consent form before entering the washout period for 2 weeks before they start their interventions. TCM group will receive acupuncture and Tui-na. PT group will receive physiotherapy training. Patients will be treated twice a week and rest on 3rd and 6th week. Total 12 sessions treatments within 8 weeks. The investigators set up a control group named "education group", the control group will be used to compare with the other two groups. Included patients in this group are provided with educational talk on knee health protection. Patients are advised with daily-life protection on their PFPS. After 8 weeks of control intervention, patients are given with treatment same as TCM group or PT group in 1:1 basis. Phone-follow up will start from 3-month after the treatment. Statistical analysis will be performed using the Social Science Statistics Package (SPSS) for Windows version. The investigators are going to (1) analysis of the PFPS diagnostic criteria; (2)Comparison between the questionnaire and examinations before and after the treatment intervention.

i. Patients in supine position with knee elevated 20-30 degrees bending using a pillow below. ii. Acupuncture needle using 0.25 mm diameter and 1.5-inch length. iii. Choose 'A shi point' to inject the acupuncture needles. iv. Inject 4 acupuncture needles respectively at the upper, lower, lateral and medial edge of the patella, along the medial and lateral edge at the posterior surface of patella. v. Connect the needles with electro-therapy, selecting high frequency and strength that the patients have sensation and acceptable. Time duration is 30 minutes each time. Infra-radiation is provided and warm above the treatment region. vi. Tui-na manipulations using the method of 'Tui-na'. Time duration is 2-5 minutes. Patella is pushed up and elevated during treatment. vii. No external herbal medicine for TCM group , other medication such as painkiller is required to record
i. Total 12 sessions of physiotherapy for 8 weeks training; ii. Treatment: Closed kinetic chain exercises program will be used when appropriate, which include: 1. Mini walk squat exercise 2. Forward step up 3. Lateral step up 4. Terminal knee extension 5. Knee taping 6. Unstable base training 7. Pain control 8. Manual Therapy Each session will approximately cost each patient 1 hours' time. There is no Chinese medicine is allowed for PT group , other medication such as painkiller is required to record.

RECRUITINGEffectiveness Measurement
The expected outcomes are both interventions have effectiveness on curing the PFPS. Traditional Chinese Medicine group and Physiotherapy group have better effectiveness than control group in treating PFPS. By according to the Visual Analogue Scale score and the before and after evaluation form, it indicates whether the pain condition has improved. (Visual Analogue Scale will be indicated from 0 to 10. Which 0 stand for no pain at all and 10 marks stand for the worst pain).
