時間枠:2 years after implantation

Clinical Performance in terms of clinical outcome of oneKNEE®. Difference in Oxford Knee Score (OKS) 2 years after implantation compared to preoperative state.

The Oxford Knee Score (OKS) is a validated joint-specific patient-reported outcome measure that is commonly employed to assess the outcome of TKA. It is a 12-item, patient-reported questionnaire originally developed and validated specifically to assess function and pain in patients undergoing TKA. It is short, reproducible, valid and sensitive to clinically important changes over time. OKS ranges from 0 to 48 with 48 being the best outcome.

Evaluation of Changes in Quality of Life
時間枠:V1= pre OP, V3= Discharge, V4= 3 months post OP, V5= 1 year post OP, V6= 2 years post OP, V7= 5 years post OP,

The EQ-5D-5L is a standardized instrument used to measure health outcomes. Developed by the EuroQol Group (EQ), it assesses five dimensions (5D) of health:

Mobility Self-care Usual activities Pain/discomfort Anxiety/depression Each dimension has five levels (5L) of severity: no problems, slight problems, moderate problems, severe problems, and extreme problems

V1= pre OP, V3= Discharge, V4= 3 months post OP, V5= 1 year post OP, V6= 2 years post OP, V7= 5 years post OP,
Evaluation of Patient Satisfaction by using PROMS: FJS
時間枠:V4= 3 months post OP, V5= 1 year post OP, V6= 2 years post OP, V7= 5 years post OP

Forgotten Joint Score (FJS) : A joint-specific questionnaire with the aim to measure PRO of joint disorders . FJS is designed to measure the ability of the patient to "forget" about their problematic joint after treatment. Scale:

  • 12 questions (How often are you aware of your affected knee joint in everyday life?)
  • 5-point response scale (0-4)
  • responses are then summed and divided by the number of completed items
  • mean value is then multiplied by 25 to obtain the total score of 0-100. A higher score indicates that the patient is less aware of their joint, suggesting better surgical outcomes and higher levels of patient satisfaction.
V4= 3 months post OP, V5= 1 year post OP, V6= 2 years post OP, V7= 5 years post OP

Knee alignment, measurement of HKA: Hip Knee Angle
時間枠:V4= 3 months post OP, V5= 1 year post OP, V6= 2 years post OP, V7= 5 years post OP
HKA: (Hip Knee Angle). The mechanical angle between the center of the femoral head, the center of the knee, and the center of the ankle. It represents the overall lower limb alignment (e.g., neutral, varus, or valgus)

Anterior knee pain
時間枠:V1= preoperatively, V4= 3 months post OP, V5= 1 year post OP, V6= 2 years post OP, V7= 5 years post OP,

Anterior knee pain is used to evaluate the performance of the implantation and the implant itself. Rating is classified according to the description of Waters and Bentley in four dimensions: 0 (no pain), I (Mild pain that does not intrude on daily activities), II (Moderate pain that is a nuisance; patient not considering further surgery), III (Severe pain; Patient considering further surgery). The scoring is according to Feller et al. 0, 5, 10 and 15 points, respectively.
