Case: A 67-year-old woman sustained a periprosthetic tibial tubercle avulsion fracture with extensor mechanism disruption. She underwent open reduction internal fixation (ORIF) with orthogonal mini-fragment plates applied in a tension band fashion with patellar tendon suture augmentation. Radiographs, range of motion, and patient-reported outcomes were completed over 1 year. Conclusion: Isolated periprosthetic tibial tubercle fractures with disruption of the extensor mechanism can be treated with ORIF using orthogonal tension band plating. At 1-year follow-up, the surgical technique described in this report yielded radiographic union, clinical restoration of preinjury motion, and excellent patient-reported outcomes.

Purpose To evaluate the outcomes of arthroscopic superior capsular reconstruction (SCR) and arthroscopy‐assisted lower trapezius tendon transfer (LTT) for posterosuperior irreparable rotator cuff tears (IRCTs). Methods Over an almost 6‐year period (October 2015 to March 2021), all patients who underwent IRCT surgery with a minimum 12‐month follow‐up period were identified. For patients with a substantial active external rotation (ER) deficit or lag sign, LTT was preferentially selected. Patient‐reported outcome scores included the visual analog scale (VAS) pain score, strength score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, Single Assessment Numeric Evaluation (SANE) score, and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. Results We included 32 SCR patients and 72 LTT patients. Preoperatively, LTT patients had more advanced teres minor fatty infiltration (0.3 vs 1.1, P = .009), a higher global fatty infiltration index (1.5 vs 1.9, P = .035), and a higher presence of the ER lag sign (15.6% vs 48.6%, P < .001). At a mean follow‐up of 2.9 ± 1.3 years (range, 1.0‐6.3 years), no differences in patient‐reported outcome scores were observed. Postoperatively, SCR patients had a lower VAS score (0.3 vs 1.1, P = .017), higher forward elevation (FE) (156° vs 143°, P = .004), and higher FE strength (4.8 vs 4.5, P = .005) and showed greater improvements in the VAS score (6.8 vs 5.1, P = .009), FE (56° vs 31°, P = .004), and FE strength (1.0 vs 0.4, P < .001). LTT patients showed greater improvement in ER (17° vs 29°, P = .026). There was no statistically significant between‐cohort difference in complication rate (9.4% vs 12.5%, P = .645) or reoperation rate (3.1% vs 10%, P = .231). Conclusions With adequate selection criteria, both SCR and LTT provided improved clinical outcomes for posterosuperior IRCTs. Additionally, SCR led to better pain relief and restoration of FE whereas LTT provided more reliable improvement in ER. Level of Evidence Level III, treatment study with retrospective cohort comparison.
