Predictive Value of the Risk Assessment and Prediction Tool (RAPT) Score for Primary Hip and Knee Arthroplasty Patients: A Single-Center Study.

The Risk Assessment and Prediction Tool (RAPT) was developed to predict patient discharge destination for arthroplasty operations. However, since Enhanced Recovery After Surgery (ERAS) programs have been utilized in the UK, the RAPT score has not been validated for use. The aim of the current study was to evaluate the predictive validity of the RAPT score in an ERAS environment with short length of stay.

Lessons learnt from managing an avulsion fracture of the tibial tubercle extending into the tibial physis.

Acute avulsions of the tibial tubercle apophysis are uncommon, with reported incidence of 0.4-2.7% of all physeal injuries.

Minimum 5-year follow-up after Cormet hip resurfacing. A single surgeon series of 234 hips.

The performance of the Cormet hip resurfacing device was evaluated after a minimum of 5 years in 234 hips. The mean age of the patients was 54 years; there were 135 men and 80 women. The primary diagnosis was osteoarthritis in 78% of the patients.

The nature and dissemination of UHMWPE wear debris retrieved from periprosthetic tissue of THR.

The role of wear debris in provoking joint replacement failure through bone resorption is now supported by much research. This study presents the analysis of 104 tissue samples using laser diffraction wear particle analysis in conjunction with standard histologic methods. The number and volume distributions were correlated to a range of joint and patient parameters.
