Reasons for malpractice claims after primary total hip arthroplasty in France: Insurance data from 240 claims from 2014 to 2017.

Introduction: Total hip arthroplasty (THA) is one of the most frequent orthopedic surgery procedures, and orthopedic surgeons are among the most frequently accused of malpractice by their patients. Identifying the main reasons for malpractice claims after THA is a prior condition to reducing their frequency. The quality of the preoperative risk information given to the patient by the surgeon is crucial for these purposes.

Bone cement implantation syndrome in hip arthroplasty: Frequency, severity and prevention.

Introduction: Cemented femoral implants incur a serious risk of potentially fatal accidents in case of bone cement implantation syndrome (BCIS). As French data are sparse regarding this issue, Orthorisq, the official accreditation body for orthopedic surgeons, conducted an inter-professional survey: 1) to assess the frequency of BCIS, 2) to analyze risk factors related to the patient and to professional practices, and 3) to set out guidelines to reduce frequency and/or severity.

Hypothesis: French data on BCIS are underestimated and need updating to ease communication between colleagues.

Is dual mobility associated with an increased risk of revision for infection? Matched cohort of 231 cases of dual-mobility cups and 231 fixed cups.

Introduction: We used a matched cohort of 231 cases of revision of primary dual-mobility cups (DMC) total hip arthroplasty (THA) and 231 cases of fixed cups (FC) THA, to determine whether (i) revision for infection was more frequent when using DMC-THA than FC-THA; (ii) Causes for revision were significantly different.

Methods: The French Society of Orthopaedics and Traumatology carried out a prospective multicentre study from 2010 to 2011. The inclusion criterion was an exhaustive collection of 1 revision THA (at least 1 component revised, re-revision excluded).

Cementless Total Hip Arthroplasty With Metasul Bearings Provides Good Results in Active Young Patients: A Concise Followup.

Background: A primary concern of younger, more active patients who have undergone total hip arthroplasty (THA) is the longevity of the implant. Cementless fixation and hard-on-hard bearings are recognized as options to enhance THA durability. Earlier, we published a series of 83 cementless primary THAs using 28-mm metal-on-metal (MoM) bearings in patients aged 50 years or younger; here we provide concise followup on that same group after an additional 8-year survey period.

Do the Reasons for Ceramic-on-ceramic Revisions Differ From Other Bearings in Total Hip Arthroplasty?

Background: Despite widespread use of ceramic-on-ceramic (CoC) in total hip arthroplasty (THA) during the past 10 years, little is known about why revisions are performed in hips with this bearing or the time elapsed before revision.

Questions/purposes: The purposes of this study were: (1) Do the reasons for first revision differ between CoC bearings and other bearing couples? (2) Does the time to revision differ between CoC and other bearing couples? (3) Are there unique reasons for revisions of CoC bearings?

Methods: All members of the Société Française de Chirurgie Orthopédique et Traumatologique (SoFCOT) who performed ≥ 30 revisions per year were invited to participate in this multicenter, prospective, observational study. Our data represent 12% of the revision procedures performed in France.

Causes for revision of dual-mobility and standard primary total hip arthroplasty : Matched case-control study based on a prospective multicenter study of two thousand and forty four implants.

Introduction: The causes for revision of primary total hip arthroplasty (THA) are various and quite well known. The developing use of dual-mobility THA (DM-THA) seems a relevant option to decrease the risk of instability. Due to lack of long-term follow-up, this innovative retentive concept is suspected to increase the risk of polyethylene (PE) wear.

What are the causes for failures of primary hip arthroplasties in France?

Background: There are no large database cohorts describing the causes for failure of primary THAs in France. Because implants and causes for revision vary between national registers, it is important to obtain data from all countries.

Questions/purposes: We therefore determined (1) the mechanisms of failure of primary THAs, (2) their order of appearance with time, (3) the types of surgical techniques and implant designs used to perform revision THAs, and (4) 90-day complications after revision THA in France.

THA using metal-on-metal articulation in active patients younger than 50 years.

Unlabelled: The main concern of patients with longer life expectancies and of patients who are younger and more active is the longevity of their total hip arthroplasty. We retrospectively reviewed 83 cementless total hip arthroplasties in 73 patients implanted with metal-on-metal articulation. All patients were younger than 50 years old (average age, 41 years) at the time of the index procedure, and 80% of the patients had an activity level graded 4 or 5 when measured with the system of Devane et al.

Metal-on-metal bearings in cementless primary total hip arthroplasty.

One hundred cementless titanium primary total hip arthroplasties with 28 mm Metasul bearings were prospectively studied (osteoarthritis in 76% of hips, mean age 59.6 years). Ninety-eight were reviewed after a 6-year average follow-up (range, 17-126 months) with clinical results graded excellent and good in 97%.
