Outcome Measures
Primary Outcomes (6)
Changes in patients reported outcome measures - Oxford Knee Score (OKS)
To explore differences between outcome in patients treated with RATKA and conventional total knee arthroplasty. Results range from 0 to 48, with higher scores corresponding to better outcomes.
At baseline (preoperatively), 6-8 weeks and 12 months postoperatively.
Changes in patients reported outcome measures - Knee injury and Osteoarthritis Outcome Score (KOOS)
To explore differences between outcome in patients treated with RATKA and conventional total knee arthroplasty. Results range from 0 to 100, with higher scores corresponding to better outcomes.
At baseline, 6-8 weeks post-operatively and 12 months post-operatively.
Changes in patients reported outcome measures - Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
To explore differences between outcome in patients treated with RATKA and conventional total knee arthroplasty. Results range from 0 to 96, with lower scores corresponding to better outcomes.
At baseline, 6-8 weeks post-operatively and 12 months post-operatively.
Changes in patients reported outcome measures - Lysholm knee scoring scale
To explore differences between outcome in patients treated with RATKA and conventional total knee arthroplasty. Results range from 0 to 100, with higher scores corresponding to better outcomes.
At baseline, 6-8 weeks post-operatively and 12 months post-operatively.
Changes in patients range of motion (ROM)
To explore differences between outcome in patients treated with RATKA and conventional total knee arthroplasty. Results range from 0 to 100, with higher scores corresponding to better outcomes.
At baseline, 6-8 weeks post-operatively and 12 months post-operatively.
*We take into consideration the possible use of other PROM questionnaires and analysis of different adverse events depending on the unpredictable circumstances.

Interventions
Participant will undergo robotic-assisted or conventional total knee arthroplasty
CT scans of the affected knee joint before and after the surgical procedure
Participants will be asked to perform biomechanical assesment before and following surgery at baseline, 6-8 weeks and 6-months postoperatively
Eligibility Criteria
You may qualify if:
- Listed for a primary total knee replacement (TKR)
- Indication for the TKR is primary osteoarthritis of the knee joint involving one or more compartments
- Aged 18 or over
- Patient willing to provide full informed consent to the trial
You may not qualify if:
- Listed for a single-stage one-sided TKR procedure
- Severe symptoms in the contralateral knee so as to require staged bilateral knee replacements within 6 months of the primary procedure
- Fixed flexion deformity of 15 degrees or greater who will require excessive resection of the distal femur
- Clinically assessed uncorrectable varus/valgus deformity of 15 degrees or greater
- Any co-morbidity which, in the opinion of the investigator, is severe enough to present an unacceptable risk to the patient's safety
- Inflammatory arthritis
- Previous septic arthritis in the affected knee joint
- Previous surgery to the collateral ligaments of the affected knee
- A contralateral total knee replacement that has been implanted less than one year from the date of consultation
- A contralateral total knee replacement that is severely painful
- Patients on warfarin or novel oral anticoagulants (NOACs)
- Will not be resident in the catchment area for at least 6 months post-surgery
- Undertaking the surgery as a private patient
- Patients who, in the opinion of the clinical staff, do not have capacity to consent
- Patients who are pregnant
- +1 more criteria
