Short-term outcomes of shoulder arthroplasty using the Comprehensive Convertible Glenoid system
- 1Sports Medicine Institute, Hospital for Special Surgery, New York, NY, USA
Abstract
Background: Glenoid loosening remains the most common cause of aseptic failure following total shoulder arthroplasty. Modern metal-backed glenoid (MBG) designs with bony ingrowth and screw fixation have been developed to address this, with promising short-term results, but data remain limited.
Methods: This is a retrospective review of prospectively collected data investigating the short-term outcomes of anatomic total shoulder arthroplasty (aTSA) in patients who received a MBG component in conjunction with their total shoulder arthroplasty at a single center with 4 surgeons specializing in shoulder arthroplasty. Patients who underwent aTSA with a modern MBG with a minimum of 2-year follow-up were identified, and data were collected regarding clinical, radiographic, and patient-reported outcomes.
Results: Twenty-eight patients (mean age 58.0 ± 6.5 years, mean follow-up 3.8 ± 1.3 years) met inclusion criteria. Range of motion improved in all measurements. American Shoulder and Elbow Surgeons improved 47.4 points (P < .001), Single Assessment Numeric Evaluation increased from 28.8 to 79.0 (P < .001), Shoulder Activity Scale from 10.0 to 13.0 (P = .008), Patient-Reported Outcomes Measurement Information System increased 17.8 (P < .001), and visual analog scale decreased from 5.2 to 2.6 (P < .001). Three patients underwent conversion to reverse shoulder arthroplasty; no cases of component loosening, polyethylene dissociation, or periprosthetic fracture were observed.
Discussion: The Comprehensive Convertible Glenoid system in aTSA demonstrates strong radiographic and clinical outcomes at short-term follow-up. This information can be useful in counseling patients regarding the results of this procedure. Long-term studies are needed to further elucidate the longevity of MBGs.
