Knee arthroplasty alignment varus survey |
| Résumé : |
Purpose: To survey an audience of international knee surgeons about their current opinions on the analysis of coronal knee alignment and their objectives for postoperative alignment in total knee arthroplasty.
Methods: Survey of 300 surgeons from 32 different countries with an audience response system allowing three possible answers being either a positive or negative answer or an abstention.
Results: Surveyed surgeons perform rarely preoperative and postoperative full leg radiographs and evaluate radiological outcomes more with short films. The main trend in this survey was towards neutral mechanical alignment, however varus alignment is acceptable in constitutional varus patients. This residual varus should be obtained through a femoral varus cut rather than a tibial varus cut. The valgus knee can remain in slight valgus but most of the correction will be performed at the femoral level. The main objective of postoperative alignment in TKA is a joint line parallel to the floor and a central loadbearing axis through the middle of the arthroplasty.
Surgeons prefer unicompartmental arthroplasty more for themselves than for their patients in case of medial bone on bone arthritis.
Conclusions: Neutral mechanical axis with a joint line parallel to the floor and a centrally running load bearing axis remains the central scope of the surveyed surgeons. Because of the literature on residual varus it becomes more acceptable for the orthopaedic community to accept this type of outlier before aiming at a surgical correction. |

| Résumé : |
Background : Based on historical data, the current standard of care in Total Knee Arthroplasty (TKA) is to restore the overall alignment to a neutral mechanical axis of 0° ± 3° or even slight valgus. However, there is significant controversy in literature regarding intentionally placing the TKA in the patient’s physiologic, rather than neutral (0 ± 3°), mechanical alignment. Questions/purposes : The goal of this review is to provide a concise update on the present knowledge of coronal plane alignment TKA in a varus population. Methods : A systematic overview of the present literature was undertaken to determine basic science and clinical results in frontal plane alignment in primary TKA. Results : Results of studies based on laboratory research, retrieval analysis, cadaver research, finite models, survival scores, clinical outcome, gait analysis and radiographic outcome upon today are provided. Conclusions : Currently placement of a TKA in neutral alignment of 0° ± 3° of frontal plane alignment is the standard of care. However, frontal plane alignment in neutral may not be as strongly correlated to survivorship as previously thought. Caution needs to be exercised before changing the standard of care, and more research needs to be performed |
