NCT ID: NCT04797897

Last Updated: 2025-03-25

Results Overview

The number of participants with knees achieving post-operative leg alignment was taken by radiographic assessment at 6 weeks. Post-operative leg alignment was achieved when the deviation from the participant specific target did not exceed ±3 degrees.

PRIMARY outcome

Timeframe: 6 weeks

Population: Overall number of participants analyzed included those enrolled in the study with data collected for the outcome and time frame specified. Leg alignment not collected for 1 participant in CORI UKA group, and target data was not collected for 1 participant in Conventional UKA group.

The number of participants with knees achieving post-operative leg alignment was taken by radiographic assessment at 6 weeks. Post-operative leg alignment was achieved when the deviation from the participant specific target did not exceed ±3 degrees.

Timeframe: 6 weeks

Population: Overall number of participants analyzed included those enrolled with data collected for the outcome and time frame specified.

Component alignment assessed on long leg standing antero-posterior (A/P) X-rays and standard non weight bearing lateral X-rays taken 6 weeks after surgery. From the A/P radiograph, the femoral flexion angle in degrees was obtained using standard radiographic tools. Femoral flexion angle is defined as the angle formed between a line across the base of the femoral condyles and a line that is centered along the femoral canal.

The Oxford Knee Score (OKS) is a Patient Reported Outcome questionnaire that was developed to assess perceived function and pain answered on a Likert scale. Responses to each question ranges from 0-4 with a range of a possible overall score from 0-48. A score of 0 is the worst possible outcome while a score of 48 is the best possible outcome.

The Forgotten Joint Score (FJS) comprises measures for the assessment of joint-specific patient reported outcomes. Participants are asked to rate their awareness of their knee arthroplasty in 12 questions with a five point Likert response format: "Never", "almost never", "seldom", "sometimes" and "mostly". The item scores are summed and linearly transformed in a 0 to 100 scale with a high value reflecting the ability of the subject to forget about the replaced knee joint during the activities of daily living (i.e., a higher score is a better outcome).

The EQ-5D-5L score consists of two parts: a descriptive system and a visual analogue scale (VAS). The descriptive system (i.e., index score) is used to describe the participant's health state and consists of five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels to choose the most appropriate answer: no problems, slight problems, moderate problems, severe problems and extreme problems. The participant is asked to indicate their health state by marking the most appropriate statement in each of the five areas. The EQ-5D-5L Index Score was based on a scale of 0 to 1, with higher index values indicating better health and lower index values indicating worse health.

The EQ-5D-5L score consists of two parts: a descriptive system and a visual analogue scale (VAS). The VAS records the participant's self-rated health on a vertical visual analogue scale. The scale ranges from 0 to 100 where 0 indicates 'The worst health you can imagine' and 100 indicates 'The best health you can imagine'.
