The aim of this study was to report the outcomes of different treatment options for glenoid loosening following reverse shoulder arthroplasty (RSA) at a minimum follow-up of two years. We retrospectively studied the records of 79 patients (19 men, 60 women; 84 shoulders) aged 70.4 years (21 to 87) treated for aseptic loosening of the glenosphere following RSA. Clinical evaluation included pre- and post-treatment active anterior elevation (AAE), external rotation, and Constant score.Aims
Patients and Methods
Instability is the reason for revision of a primary
total knee replacement (TKR) in 20% of patients. To date, the diagnosis
of instability has been based on the patient’s symptoms and a subjective
clinical assessment. We assessed whether a measured standardised
forced leg extension could be used to quantify instability. A total of 25 patients (11 male/14 female, mean age 70 years;
49 to 85) who were to undergo a revision TKR for instability of
a primary implant were assessed with a Nottingham rig pre-operatively
and then at six and 26 weeks post-operatively. Output was quantified
(in revolutions per minute (rpm)) by accelerating a stationary flywheel.
A control group of 183 patients (71 male/112 female, mean age 69
years) who had undergone primary TKR were evaluated for comparison. Pre-operatively, all 25 patients with instability exhibited a
distinctive pattern of reduction in ‘mid-push’ speed. The mean reduction
was 55 rpm ( Cite this article:
