Failure rates and patient-reported outcomes of revision of total ankle arthroplasty.
Despite the increasing number of revision total ankle arthroplasty (TAA), the literature on indications, surgical options, and outcomes is limited. This study reports on failure rates and patient-reported outcomes (PROM) for a cohort of 122 patients who underwent revision of TAA. ⋯ The high failure rate of polyethylene exchange indicates that the intervention does not address the actual cause of failed TAA in many cases. Additional axis correction should be considered more frequently. If the underlying issues of prosthesis failure can be identified and sufficiently addressed, the results of revision surgery are likely to improve.

Periprosthetic knee infection in octogenarians: a single institution experience at midterm outcome.
Periprosthetic joint infections (PJI) of total knee arthroplasties (TKAs) in the elderly is among the clinically most challenging scenarios given multimorbidity combined with poor bone and soft tissue quality. Despite increasing prevalence, limited is known on PJI among this unique group of patients. As such, this study analyzed PJI characteristics, implant survivorship and non-surgical complications of octogenarians revised PJI for the knee. ⋯ Therapeutic level IV.

The clinical outcome of total knee arthroplasty is compromised by a previously implanted medial unicondylar knee arthroplasty.
To investigate the clinical outcome of patients that underwent conversion of a medial unicondylar knee arthroplasty (UKA) to a total knee arthroplasty (TKA) and to compare that outcome to patients that underwent primary TKA. It was hypothesized that those groups would significantly differ in terms of knee score outcome and implant survival. ⋯ Based on our findings it is concluded that patients who received a TKA after UKA have inferior results than those that directly receive a TKA. This is true for both patient-reported knee outcome and prosthesis survival. Converting UKA to TKA should not be seen as an easy operation, but should rather be done by surgeons with considerable experience in both primary and revision knee arthroplasty.

Stem size prediction in shoulder arthroplasty with preoperative 3D planning.
Three-dimensional surgical planning software provides virtual reconstructions of the shoulder with automated joint indices for a preoperative case assessment. The aim of this single center study was to evaluate the concordance between the preoperatively selected humeral components and the final implants used in shoulder arthroplasty. ⋯ level IV, retrospective case study.

Ossification of the posterior capitellum: description of a new pathology and its radiological appearance.
Boxer elbow and handball goalkeeper elbow are causes of impingement characterized by osteophytes formation at the olecranon and coronoid tip as well as their corresponding fossae. Herein, we present another distinct pathology in these patients: the formation of an exostosis at the posterolateral aspect of the elbow. ⋯ In patients without history of elbow trauma, bony irregularities of the posterior aspect of the capitellum may indicate ossification of the posterolateral aspect of the elbow, most likely caused by repetitive hyperextensions.
