Brief Summary
- 1.To develop a new type of knee joint pressure detection device and demonstrate its feasibility
- 2.To analyze individual differences of knee ligament tension using the new device and explore the influencing factors of ligament tension
- 3.To explore the correlation between knee ligament tension and postoperative knee function

Outcome Measures
Primary Outcomes (6)
Ligament tension
Measure the medial and lateral ligament tension of the operative knee at different flexion angle
During operation
Pre-operative knee function
Assess the knee function using AKS (The American knee society, 0\~200, higher scores mean a better outcome) scale before operation
1day before operation
Post-operative knee function
Assess the knee function using AKS scale at the 3rd day post-operation
The 3rd day after operation
Post-operative knee function
Assess the knee function using AKS scale at the 6th week post-operation
The 6th week after operation
Post-operative knee function
Assess the knee function using AKS scale at the 3rd month post-operation
The 3rd month after operation
Post-operative knee function
Assess the knee function using AKS scale at the 12th month post-operation
The 12th month after operation
Secondary Outcomes (6)
Pre-operative infection test

Study Arms (1)
Ligament tension measurement group
All participants will receive ligament tension measurement by the tension device during operation
Interventions
A gap plate can measure knee joint pressure by tension sensor. This is a part of routine medical care.
Eligibility Criteria
Study population are those receiving primary knee arthroplasty
You may qualify if:
- Patients receiving primary knee arthroplasty
You may not qualify if:
