Shoulder arthroplasty for proximal humeral fracture treatment: a retrospective functional outcome analysis.

Purpose: Following proximal humeral fractures hemiarthroplasty (HA) or reversed total shoulder arthroplasty (rTSA) are performed if osteosynthesis or conservative treatment is not possible. HA has been reported to result in decreased functional outcomes compared with rTSA. Secondary shoulder arthroplasty, performed after a different initial treatment, has also been associated with inferior outcomes.

Proximal humeral fracture-dislocation: Outcome analysis in osteosynthesis and arthroplasties.

Purpose: Proximal humeral fracture-dislocations (PHFD) are challenging to treat. In older patients, usually arthroplasty is performed. In younger patients, osteosynthesis is chosen.

The lack of retropatellar resurfacing at index surgery is significantly associated with failure in patients following patellofemoral inlay arthroplasty: a multi-center study of more than 260 patients.

Purpose: To evaluate the clinical outcomes of patients with a minimum 2-year follow-up following contemporary patellofemoral inlay arthroplasty (PFIA) and to identify potential risk factors for failure in a multi-center study.

Methods: All patients who underwent implantation of PFIA between 09/2009 and 11/2016 at 11 specialized orthopedic referral centers were enrolled in the study and were evaluated retrospectively at a minimum 2-year follow-up. Clinical outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Tegner Scale, the visual analogue scale (VAS) for pain, and subjective patient satisfaction.
