Blood loss
Tidsramme: 3 days after surgery
|
Postoperative drainage volume refers to the drainage volume of the affected knee within 24 hours after the end of surgery, accurate to ml.Gross linear equation was used to calculate the total blood loss and latent blood loss at 3 days after surgery.

the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Tidsramme: 3 months、6 months and 12 months after surgery
|
The WOMAC is a self administered questionnaire to assess joint function and quality of life for patients with osteoarthritis; it consists of 24 items: pain (5 items), stiffness (2 items), and physical function (17 items).
The higher the total score, the worse the patient's pain, stiffness, and functional limitations.
The WOMAC is validated for various languages, including Chinese.

HSS(Hospital for Special Surgery) score
Tidsramme: 6 months and 12 months after surgery
|
HSS(hospital for special surgery) score HSS(hospital for special surgery) score to evaluate patients postoperative knee joint function.
With a total of 100, it has 7 subscales: 1.Pain 0~30; 2. Function 0~22; 3. Mobility 0~18; 4. Flexion deformity 0~10; 6. Stability 0~10; 7. Deduction Item.
For each scale, a higher value represents a better outcome.
The sum of the subscales is the total score.

Forgotten Joint Score-12 (FJS-12)
Tidsramme: 6 months and 12 months after surgery
|
The FJS-12 is a PROM for patients who have undergone a TKA; it introduces the concept of a "forgotten" joint as the ideal objective to pursue in prosthetic surgery.
It is composed of 12 items, measuring the patient's ability to forget the presence of an artificial joint in their daily life.
For each item, there is a five-points Likert scale response.
The raw results are converted to a 0-100 points scale.
Highest score corresponds to good outcome with the patient not aware about the presence of the prosthesis.
In the case of more than 4 answers are missing, the score should not be used .
