Discovery Elbow System arthroplasty polyethylene bearing exchange: outcomes and experience.

Background: The Discovery Elbow System (DES) utilizes a polyethylene bearing within the ulnar component. An exchange bearing requires preoperative freezing and implantation within 2 minutes of freezer removal to allow insertion. We report our outcomes and experience using this technique.

Does long-term follow-up and monitoring of primary shoulder arthroplasty identify failing implants requiring revision?

Background: Published scoping review has identified evidence paucity related to long-term follow-up of shoulder arthroplasty. We aim to report effectiveness of elective primary shoulder arthroplasty surveillance in identifying failing implants requiring revision.

Methods: A prospective database recording shoulder arthroplasty and subsequent follow-up surveillance in a shoulder unit was analyzed.

Minimum five-year outcomes of reverse total shoulder arthroplasty using a trabecular metal glenoid base plate.

Aims: Reverse total shoulder arthroplasty (RTSA) using trabecular metal (TM)-backed glenoid implants has been introduced with the aim to increase implant survival. Only short-term reports on the outcomes of TM-RTSA have been published to date. We aim to present the seven-year survival of TM-backed glenoid implants along with minimum five-year clinical and radiological outcomes.

Mid- to long-term survivorship of the cemented, semiconstrained Discovery total elbow arthroplasty.

Background: The incidence of total elbow arthroplasty (TEA) is increasing, and an improved understanding of elbow kinematics and biomaterials has driven advances in implant design. In modern practice, cemented, semiconstrained devices are most frequently used. The Discovery TEA has demonstrated promising early results, although there are a paucity of follow-up studies and no dedicated mid- to long-term series.

Outcomes for a large metaphyseal volume hemiarthroplasty in complex fractures of the proximal humerus.

Background: A large metaphyseal volume shoulder hemiarthroplasty has been in use within our department since 2008; however, no clinical outcome data are available for this prosthesis apart from the designer surgeon series.

Materials And Methods: During a 5-year period, data were collected for 40 patients (30 women, 10 men) treated consecutively with the Zimmer Anatomical Shoulder Fracture hemiarthroplasty system (Zimmer, Warsaw, IN, USA).

Results: The final analysis included 26 patients.

The octogenarian total knee arthroplasty.

Sixty-five patients aged > 80 years were compared to 65 patients aged between 60 and 70 years to assess total knee arthroplasty (TKA) outcome using the octogenarian postoperative Knee Society knee and function scores. Knee Society knee scores showed excellent outcomes with no statistically significant difference in the younger cohort (preoperative score, P = .7156; 5-year score, P = -.
