Brief summary
This prospective cohort study was conducted with the aim of comparing relevant clinical outcomes which included intra (surgical time and blood loss), post-operative outcomes (range of motion, function, complications and revisions) and return to activity between imageless and image-based surgical system in medial unicondylar knee arthroplasty
Detailed description
this prospective cohort study was conducted between 1st June 2015 and 1st July 2018 at Bhumibol Adulyadej Hospital, Bangkok, Thailand. A total of 33 medial compartment OA knee patients were randomly allocated to MAKO or NAVIO robotic assisted UKA. The outcomes assessed were intra-operative outcomes (operative time, blood loss) and postoperative outcomes (function, complications and revision) at 1 year after surgery.

Inclusion criteria
* patients were those deemed suitable for unicondylar knee arthroplasty surgery * patients who could give informed consent * patients who willing to attend the prescribed follow-up.
Exclusion criteria
* Patients who have medial osteoarthritis knee with following condition: 1. Ligament insufficiency (anterior cruciate ligament rupture, collateral ligament insufficiency). 2. Inflammatory arthritis 3. A deformity requiring augmentation 4. Neurological movement disorders 5. pathology of the feet, ankles, hips, or opposite knee causing significant pain or gait alterations * Patients who ultimately required a total knee arthroplasty (valgus greater than 14 degree, multiple compartment osteoarthritis were contraindications to unicondylar knee arthroplasty.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| operative time | 1 day | operative time in minutes the higher value of blood loss is worse outcome |
| calculated total blood loss | 1 day | total blood loss which was calculated using a formula based on patient blood volume and a decrease in hemoglobin |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| post operative complications | 12 months | post operative complications included infection, wound complication, stiffness and revision. the higher number of post operative outcome is the worse outcomes |
