• 1 other identifier: 8193
• Study Type: observational
• Target: 500
• Locations: 1 country
• Sites: 1

Brief Summary

The aim of this study was to analyze the coronal alignment of a large population of patients undergoing total knee arthroplasty using a modern classification of the knee phenotypes found in a population of non-osteoarthritic patients.

Conditions

Osteoarthritis, Knee

Keywords

Knee; Osteoarthritis; Knee osteoarthritis; knee arthroplasty; Total knee arthroplasty; Navigated implantation

Outcome Measures

Primary Outcomes (1)

• Percentage of subjects with normal overall coronal alignment, defined by the association of a normal native medial distal femoral angle and a normal native medial proximal tibial angle

  Files analysed retrospectively from January 01, 2011 to February 28, 2021 will be examined]

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patient aged ≥ 18 years operated between 01/01/2011 to 02/28/2021 by two experienced surgeons of a total knee prosthesis using a navigation system without image (OrthoPilot ®, Aesculap, Tuttlingen, FRG) allowing to measure during the intervention the anatomical parameters of the subject before implantation;

You may qualify if:

• Patient aged ≥ 18 years
• Patient operated between 01/01/2011 to 02/28/2021 by two experienced surgeons of a total knee prosthesis using a navigation system without image (OrthoPilot ®, Aesculap, Tuttlingen, FRG) allowing to measure during the intervention the anatomical parameters of the subject before implantation;
• Records including a complete intraoperative anatomical analysis;
• Subject who has not expressed his opposition, after being informed, to the reuse of his data for the purposes of this research.

You may not qualify if:

• Subject who expressed their opposition to participating in the study
• Impossibility of giving the subject informed information (difficulties in understanding the subject, etc.)
• Incomplete or absent anatomical analysis
• Subject under guardianship, curatorship or safeguard of justice
