Brief summary
Knee osteoarthritis (KOA) is one of the most common musculoskeletal diseases in clinic. It usually occurs in middle-aged people, especially women. An estimated lifetime risk for KOA is approximately 40% in men and 47% in women. KOA is a chronic disease which can lead to obvious pain, joint stiffness, limitation of activity and even disability, with significant associated costs and effects on society, health systems, and individuals. Tuina therapy has been used and showed effectiveness and safety for pain relief and disability for the patients with musculoskeletal disorders for years in China. Though it is regarded that the Traditional Chinese medicine (TCM) Tuina therapy is similar to the modern manual therapies, the modalities of TCM tuina therapy are different and effect maybe equal to or more better than the modern manual therapy in clinic. However, little evidence exists that Tuina benefits the KOA. The investigators will do this in a randomized, parallel, active controlled study to observe whether TCM Tuina is more beneficial to KOA than the physical manual therapy, which has been considered an effective and standard care for KOA.
Detailed description
Patients will be randomly allocated to one of two groups. In the Chinese Tuina group (group CTG), patients will receive the traditional Chinese Tuina therapy (including rolling, grasping, scratching, pressing, acupressure or pushing) on the basis of KOA health education and home-exercise. Patients in the Physical Manual group (group PMG) will receive the modern physical manual therapy (including joint mobilization/manipulation, manual traction, soft tissue manipulations, passive stretching, range of motion and strength training) on the basis of KOA health education and home-exercise. Assessments will be conducted at baseline and 4 and 16 weeks after randomization. It is expected that the interventions will alleviate the sufferings of the patient. The risks of participation are minimal. Occasionally, tuina can make people feel nauseous or experience a temporary increase in pain either during or after treatment. Rare side effects happen during and after Tuina or manual treatment.
Interventions
1. The doctor presses the affected lower limb from the anterior superior iliac spine to the ankle; 2. The doctor gives the pressure on the Biguan(ST31), Futu(ST32), Heding(EX-LE2), Neixiyan(EX-LE4), Waixiyan(Dubi, ST35), Zusanli(ST36) and Sanyinjiao(SP6) of the affected lower limb; 3. Massage the spleen and stomach meridians of the affected lower extremes; 4. Roll the soft tissues around the affected knee; 5. Relax the gastrocnalis muscle 6. The doctor gives the pressure on the Xuehai(SP10), Liangqiu(ST34), Neixifeng(medial patellofemoral ligament), Waixifeng(lateral patellofemoral ligament), Neixiyan(EX-LE4) and Waixiyan(Dubi, ST35) at the same time; 7. Push the patella and do the passive movement of the affected knee; 8. Strength training of the affected knee. This group receives 8 treatments over a 3 week period with a one week follow-up on site and a 3 month follow-up by mail, phone or email.
OTHERPhysical Manual therapy
1. Manual therapy: Stretching the knee joint, stretching the knee joint with valgus or abduction, stretching the knee joint with varus or adduction is suitable for patients with knee flexion and extension difficulty.Patellar manipulation by bending the knee 5-10 degrees downward is suitable for patients with patellar sliding difficulty.The lower end of the muscle length manipulation is suitable for patients with muscle tension and soft tissue tension.Soft tissue loosening is performed in the suprapatellar and peripatellar regions, medial and lateral capsule joints, and popliteal fossa. 2. Activity training: Mainly about the knee joint flexion and extension movement training. 3. Strength training: Mainly about quadriceps muscle resistance exercises This group receives 8 treatments over a 3 week period with a one week follow-up on site and a 3 month follow-up by mail, phone or email.

Masking
DOUBLE (Subject, Outcomes Assessor)
Masking description
Participants are randomly divided into Chinese Tuina group and Physical Manual group at a ratio of 1:1, only knowing that they will receive the manual therapies. The assessor, data manager and statistician will not participate in the randomized process and the treatment and share any information with each other.
Intervention model description
Two arms recruit and evaluate the participants at the same time, and the included participants have the equal opportunity to either the Chinese Tuina or physical manual therapy groups.

Inclusion criteria
1. Diagnosis of KOA; 2. Age 40-75 years; 3. KL (Kellgren-Lawrence) grade Ⅱ or Ⅲ in recent 3 months; 4. NRS score of pain at least more than 4 points; 5. Single/bilateral knee pain, duration of more than 6 month; If the patient has KOA on both legs, the heavier leg is selected for study.
Exclusion criteria
1. Surgery history of knee or waiting for surgery (knee replacement or knee arthroscopy); 2. Knee pain caused by other diseases (such as joint bodies, severe effusion of joint cavity, infection, malignant tumors, autoimmune diseases, trauma, etc.); 3. Oral administration of hormones within 3 month, intra-articular injection within 6 months, knee injuries or open injuries within 6 months, or knee arthroscopy within 1 year. 4. Severe acute/chronic organic or mental diseases; 5. Pregnant women, pregnant and lactating women; 6. Coagulation disorders (such as hemophilia, etc.), or the skin diseases at the site of operation; 7. Device support treatment after knee osteoarthritis disability; 8. Participation in another clinical study in the past 3 months; 9. History of receiving acupuncture, massage, manipulation, or any medical plaster treatment within 3 months 10. Breaks for treatment longer than 3-4 weeks depending on each circumstance or merit may be construed as non-compliance and may be excluded.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Western Ontario and McMaster University Osteoarthritis Index (WOMAC) | Change from baseline at 4 weeks | Self report measure of pain, stiffness, and physical function for people with knee osteoarthritis. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Numeric Knee Pain Rating Scale | Change from baseline at 4 weeks, 8 weeks and 16 weeks | Subjects will rate their worst knee pain in the last 24 hours using an 11 point numeric pain rating scale with 0 representing no pain and 10 representing the worst pain imaginable. |
| Change in Patient Global Assessment (PGA) | Change from baseline at 4 weeks, 8 weeks and 16 weeks | The Patient global assessment rating is a 11 point Numeric Rating Scale in which subjects will rate the degree to which their knee condition has changed from the time treatment was initiated to the present. The subject responds to the following query: Please rate your overall knee's condition from the time you began treatment until now. using an 11 point numeric rating scale with 0 representing A very great deal better and 10 representing A very great deal worse. |
