Satisfactory mid- to long-term outcomes of TKA aligned using conventional instrumentation for flexion gap balancing with minimal soft tissue release.

Purpose: To describe a technique for flexion gap management in total knee arthroplasty (TKA) using conventional instrumentation with minimal soft tissue release, by aligning the femoral component to restore close-to-native posterior condylar angle (PCA). The hypothesis was that this technique renders consistent outcomes, regardless the preoperative deformity or intraoperative parameters.

Methods: In a consecutive series of 152 TKAs, the femoral component was rotated to restore anatomic PCA of 2° ± 2° and the flexion gap was balanced with a final lateral flexion laxity of 1-3 mm.

No difference in 13-year survival after medial pivot or central pivot mobile bearing total knee arthroplasty. A propensity matched comparative analysis.

Purpose: The present study was designed to evaluate the long-term results (more than 10 years) of mobile bearing total knee arthroplasty (TKA) and to compare the survival of medial pivot axis (MPA) and central pivot axis (CPA) TKAs. The primary hypothesis was that the 10- to 15-year survival rate of MPA TKAs will be better than CPA TKAs.

Methods: A national, multicenter, retrospective study was performed in France.

Navigation Improves the Survival Rate of Mobile-Bearing Total Knee Arthroplasty by Severe Preoperative Coronal Deformity: A Propensity Matched Case-Control Comparative Study.

The primary hypothesis of this study was that the survival rate over 10 years of total knee arthroplasties (TKAs) implanted with a navigation system was superior to that of TKAs implanted with a conventional technique. The secondary hypothesis was that the severity of the initial coronal deformity had a negative influence on the survival rate. A national, multicentric, retrospective study was performed in France, including eight university or private centers with high volumes in knee surgery.

Inconsistent relationship between body weight/body mass index prior to total knee arthroplasty and the 12-year survival.

Background: The primary hypothesis was that body weight (BW) and body mass index (BMI) significantly impact the long-term survival rate after implantation of a mobile bearing total knee arthroplasty (TKA).

Methods: A national, multicentric, retrospective study was performed in France. A total of 1604 TKAs were included.

Predictive Factors of "Forgotten Knee" Acquisition After Total Knee Arthroplasty: Long-Term Follow-Up of a Large Prospective Cohort.

Background: In a large prospective cohort, we recently showed that only 66.1% of total knee arthroplasty (TKA) with a perfect outcome according to Knee Society Knee Score was completely forgotten in all everyday activities. The main objective of this study was to identify clinical and orthopedic factors associated with the acquisition of "forgotten knee" (FK).

Functional Results of the ROCC® Mobile Bearing Knee. 602 Cases at Midterm Follow-Up (5 to 14 Years).

Unlabelled: We report midterm results of a prospective continuous cohort of ROCC® Total Knee Arthroplasties (TKA). Between 2001 and 2008, all primary TKA patients (n=500) received 602 ROCC saddle-shaped rotating platform TKAs. Mean follow-up was 7.

"Forgotten knee" after total knee replacement: A pragmatic study from a single-centre cohort.

Objectives: After total knee replacement (TKR), some patients find their operated knee totally natural and can be said to have "forgotten" it, while others, although satisfied with their results, remain conscious of their prosthesis. This is not well assessed on conventional end-points. Since 2001, we have studied the prevalence of "forgotten knee" (FK) after TKR in a prospective pragmatic cohort, with comparison to conventional scores.

Predictors of flexion using the rotating concave-convex total knee arthroplasty: preoperative range of motion is not the only determinant.

Purpose: The range of motion achieved after a total knee arthroplasty (TKA) affects many daily activities and overall patients' satisfaction. This study aims to define the determinants affecting post-operative midterm active flexion according to a specific cruciate-sacrificing prosthesis, the rotating concave-convex (ROCC(®)) TKA.

Method: Four hundred and eighty-four consecutive patients (584 TKAs) were prospectively followed.
