Performance of medial pivot, posterior stabilized and rotating platform total knee arthroplasty based on anteroposterior stability and patient-reported outcome measures; a multicentre double-blinded randomized controlled trial of 210 knees.

Background: Despite advancements in total knee arthroplasty (TKA), 10-20% of patients remain dissatisfied after surgery. Improved anteroposterior (AP) stability provided by medial pivot (MP) implants may theoretically lead to higher patient satisfaction.

Methods: AP stability and patient-reported outcome measures (PROMs) at one-year postsurgery were compared between patients who underwent TKA with MP- (n = 121), posterior stabilized (PS; n = 53) and rotating platform (RP; n = 57) implants in a double-blind multicentre randomized controlled trial (Dutch Trial Register: NL6856, 21-02-2018).

Antibiotic prophylaxis before tissue biopsy has no effect on culture results in presumed aseptic revision total hip arthroplasty.

: Antibiotic prophylaxis (AP) is considered to be the gold standard for revision total hip arthroplasty (R-THA) due to the high incidence of prosthetic joint infection (PJI). To diagnose PJI, intraoperative tissue biopsies for culture are of particular importance. However, antibiotic interference could theoretically lead to less reliable culture results.

Excellent Long-Term Results of an Austin Moore Hemiarthroplasty After Half a Century: A Case Report.

Case: We present the unique case of a 73-year-old man who was treated 50 years ago with a hemiarthroplasty (HA) for avascular necrosis after a femoral neck fracture (FNF) of his left hip and who has developed only mild osteoarthritis since and has reported satisfactory clinical and functional outcomes with no acetabular erosion.

Conclusion: HA for FNFs can provide durable long-term results and can, therefore, be considered as an option in the treatment of FNFs in younger patients. We describe a case with good results after 50 years, which, to our knowledge, is the longest reported follow-up of HA.

Iatrogenic common peroneal nerve injury during harvesting of semitendinosus tendon for anterior cruciate ligament reconstruction.

We present a case of iatrogenic injury to the common peroneal nerve (CPN) occurring due to harvesting of a hamstring graft, using a posterior mini-incision technique. A twitch of the foot was noted on retraction of the tendon stripper. After clinically diagnosing a CPN palsy proximal to the knee, the patient was referred to a neurosurgeon within 24 hours.

Fatigue fracture of an uncemented Zweymüller femoral stem at the neck-shoulder junction.

A fracture through the neck of the femoral stem in total hip arthroplasty is extremely rare. We report a neck fracture of a cementless Zweymüller stem, one of the most implanted stems worldwide. According to our knowledge, this is the first thorough case description of a neck fracture of a cementless Zweymüller stem.

Direct Anterior Approach for One-Stage Bilateral Total Hip Arthroplasty in an ASA 3 Wheelchair-Dependent Woman.

This case report involves a 79-year-old wheelchair-dependent woman with bilateral destructive coxarthrosis, requiring total hip arthroplasty (THA). Mobilization and transfers were unbearable due to the bilateral involvement of her hips. Performing unilateral THA would not be sufficient due to the coexisting pain from the contralateral side.

No decline in high patient satisfaction after total hip arthroplasty at long-term follow-up.

Introduction: Patient satisfaction is gaining popularity as an important outcome parameter in today's healthcare system and in particular in evaluating the outcome of joint arthroplasty. Total hip arthroplasty (THA) is a very successful procedure with reports on high patient satisfaction at short-term follow-up. Commonly used clinical outcome parameters remain good at long-term follow-up; however, whether this also accounts for patient satisfaction remains unclear.

The validation of the visual analogue scale for patient satisfaction after total hip arthroplasty.

INTRODUCTION: Patient satisfaction becomes more important in our modern health care system. The assessment of satisfaction is difficult because it is a multifactorial item for which no golden standard exists. One of the potential methods of measuring satisfaction is by using the well-known visual analogue scale (VAS).

Timing of arthroplasty, what is the influence of nocturnal pain and pain at rest on the outcome?

Purpose: The purpose of this study was to investigate whether nocturnal pain and pain at rest preoperatively influence the satisfaction in patients after joint arthroplasty. The second research question is whether subjective outcome (VAS/WOMAC) after hip (THA) or knee arthroplasty (TKA) differs in patients with or without nocturnal pain and pain at rest preoperatively compared to those who do not.

Methods: A consecutive group of 189 TKAs and 189 THAs was evaluated.

Surgeon's expectations do not predict the outcome of a total knee arthroplasty.

Introduction: It is fascinating for both the patient and the surgeon to predict the outcome of a TKA at an early stage. Satisfaction after TKA is primarily determined by the preoperative expectations of the patient. The purpose of this study was to investigate if the peri-operative expectations of the surgeon predicted the outcome of a TKA.

Patients are more satisfied than they expected after joint arthroplasty.

The aim of this study was to compare the preoperative patients' expectations with their postoperative satisfaction after arthroplasties of the hip and knee, using a visual analogue scale. The comparison was made in a group of 44 patients after 44 primary knee and hip joint arthroplasties. A visual analogue scale (VAS) was used for the assessment of expectation and satisfaction.

Surgeon satisfaction agreement after total knee arthroplasty using a visual analogue scale: a single surgeon series.

Introduction: The outcome of total knee arthroplasty (TKA) is traditionally rated by objective criteria such as the knee society clinical rating system (KSCRS). Subjective criteria, such as satisfaction, will be of more importance, because health-care is shifting towards a market model. The aim of this study was to investigate the agreement on satisfaction after TKA between two orthopaedics surgeons, when one of the surgeons reviews his own results.

Are surgeons equally satisfied after total knee arthroplasty?

Introduction: We performed a clinical follow-up study to investigate whether three orthopaedic surgeons were equally satisfied after total knee arthroplasty (TKA).

Patients And Methods: Thirty-six patients (39 TKAs, mean follow-up 12 months) were reviewed, using the Knee Society Clinical Rating System (KSCRS). For the assessment of satisfaction a visual analogue scale (VAS) was used.

Patient versus surgeon satisfaction after total hip arthroplasty.

We compared patient satisfaction with surgeon satisfaction after total hip arthroplasty (THA) in a group of 193 patients (200 THAs, mean follow-up six years) using a visual analogue scale (VAS), and two objective and two subjective scoring systems. We also determined the survival rate with different endpoints. For the 121 hips available for clinical follow-up, we did not find a significant difference in satisfaction between patient and surgeon.
