Safety of the implant
時間枠:2 years after implantation

Clinical Performance in terms of clinical outcome of oneKNEE®
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. |

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. (Feller et al., J Bone Joint Surg Am. 2003 Feb;85(2):212-7). |
