RESUMO

PURPOSE: To compare outcomes of reverse shoulder arthroplasty (RSA) for primary osteoarthritis (OA) with and without rotator cuff (RC) tears to those with secondary OA due to RC tears. METHODS: We reviewed records of all patients who received RSA for primary OA or secondary OA. All patients had preoperative radiographs, computed tomographic arthrography (CTA), and/or magnetic resonance imaging (MRI) scans of their shoulders to assess their etiology, glenoid morphology, and fatty infiltration. Pre- and postoperative (at minimum follow-up of 2 years) Constant scores and range of motion were compared between patients who had RSA for primary OA with and without RC tears to those with secondary OA due to RC tears. RESULTS: Of the initial cohort of 605 shoulders (583 patients), 153 were lost to follow-up (25.3%), 25 required revision with implant removal (4.1%), and 13 died of causes unrelated to the surgery (2.1%), and left a final cohort of 414 patients. Of the final cohort, 97 had primary OA with intact RC, 62 had primary OA with RC tears, and 255 had secondary OA. Postoperative Constant scores were significantly higher for primary OA with intact RC (73.8 ± 14.3), compared with both primary OA with RC tears (66.1 ± 14.6, P < .001) and secondary OA (64.1 ± 14.8, P < .001). There were no differences in pre- or postoperative scores between primary OA with RC tears and secondary OA. CONCLUSION: At 2 or more years following RSA, Constant scores were significantly higher for primary OA with intact RC, compared to either primary OA with RC tears or secondary OA, whereas there were no differences in pre- or postoperative scores of shoulders that had primary OA with RC tears vs. secondary OA. The authors recommend distinguishing primary OA with intact RC from primary OA with RC tears, as the two have considerably different characteristics and prognosis following RSA.

RESUMO

BACKGROUND: Return to sport after stabilization surgery using the open Latarjet procedure remains challenging. Additional knowledge is needed about postoperative shoulder functional deficits in order to better design return-to-sport programs. PURPOSE: To investigate the effects of the dominance status of the operated shoulder on the shoulder functional profile recovery at 4.5 months after open Latarjet procedure. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: A retrospective analysis of prospectively collected data was performed. All patients who underwent the open Latarjet procedure between December 2017 and February 2021 were eligible for the study. Functional assessment at 4.5 months after the surgery was performed using the following tests: maximal voluntary isometric contractions in glenohumeral internal and external rotation, upper-quarter Y balance test, unilateral seated shot-put test, and modified closed kinetic chain upper extremity stability test, leading to 10 outcome measures. Patients whose dominant side had undergone surgery and those whose nondominant side had undergone surgery were compared with a group of 68 healthy control participants. RESULTS: A total of 72 patients who underwent an open Latarjet procedure on the dominant side and 61 patients who underwent open Latarjet on the nondominant side were compared with 68 healthy control athletes. In patients whose dominant shoulder had undergone surgery, significant deficits for the dominant side (P < .001) and for the nondominant side (P < .001) were found in 9 of 10 functional outcome measures. Among patients whose operations were on the nondominant shoulder, significant deficits for the nondominant side (P < .001) and for the dominant side (P < .001) were found in 9 and 5 of the 10 functional outcome measures, respectively. CONCLUSION: Regardless of dominance of the stabilized shoulder, persistent deficits in strength, stability, mobility, power, and stroke frequency were observed at 4.5 months postoperatively. Stabilization of the dominant shoulder resulted in residual surgery-related functional impairments on both sides. However, stabilization of the nondominant shoulder resulted in impairments primarily noted in the nondominant, operative shoulder. REGISTRATION: NCT05150379 (ClinicalTrials.gov identifier).
