RESUMEN
BACKGROUND: Patellar tendon rupture (PTR) is extremely rare but serious complication after primary or revision total knee arthroplasty. Due to the serious failure rates of end-to-end repair techniques, various augmentation techniques have been described. In this study, the results of patients with PTR after reconstruction using our own technique with semitendinosus (ST) and gracilis tendons taken from the affected side were evaluated retrospectively. METHODS: A total of 14 patients, whose diagnosis was made based on physical examination and clinical findings, and supported radiologically (ultrasonography), were included in the study. In these patients, reconstruction was performed using double-row repair technique with the ST and gracilis tendons. Active-passive knee joint range of motion, active knee extension loss, and the Caton-Deschamps index at preoperative and final follow-up visits were compared. Tegner-Lysholm knee score and Kujala score were used to evaluate functional results. RESULTS: In 14 patients (8 women and 6 men) with a mean age of 68.1 years, the median time between injury and surgery was 6.6 weeks. In all patients, the rupture was in the distal part of the patellar tendon. While the median preoperative Caton-Deschamps index was 1.8, the postoperative median value was found to be 1.25 after an average follow-up of 3.8 years (Pâ =â .014). The median preoperative knee extension loss decreased from 25° to 5° postoperatively. Tegner-Lysholm knee score and Kujala score of the patients at their last follow-up were significantly increased (Pâ <â .01). CONCLUSION: For PTR developing after total knee arthroplasty, the double-row reconstruction technique with ST and gracilis tendons is effective.

BACKGROUND: The precise influence of plate position on clinical outcomes in the context of volar fixed-angle plating for distal radius fractures is not fully understood. This article aims to investigate the influence of plate position on clinical results, and functional outcomes in patients treated with volar fixed plating for distal radius fractures. METHODS: A total of 58 patients with 64 distal radius fractures were included in the study. Patient demographics, fracture characteristics, surgical details, and radiographic data were collected. Post-operative AP and Lat views of all patients taken on the first day after surgery were evaluated. Volar Tilt, Radial Inclination and Radial Height measurements were used as reduction criteria. In the follow-up, the patients were called for their last control, flexion and extension angles of the wrist and Mayo Wrist Scores, the distance of the plate to the joint line and the angle between the plate and the radial shaft were measured and recorded. RESULTS: A total of 64 distal radius fractures, with a mean age of 46.9 years, and the mean follow-up period 24.9 months were included in this study. There was a significant relationship between the Radial Inclination and Plate-Shaft Angle variables and the Mayo Wrist Score at a 99% confidence interval. Additionally, a relationship was observed between the Radial Height variable and the Mayo Score at a 90% confidence interval. A significant positive association was observed between radial inclination and achieving a Good-to-Excellent Mayo score (OR = 1.28, 95% CI [1.08-1.51], p = 0.004). Plate distance to joint line demonstrated a marginally significant positive association with a Good-to-Excellent Mayo score (OR = 1.31, 95% CI [0.97-1.77], p = 0.077). Univariate analysis revealed a significant negative association between plate-shaft angle and achieving a Good-to-Excellent Mayo score (OR = 0.71, 95% CI [0.52-0.99], p = 0.045). This negative association remained statistically significant in the multivariate analysis (p = 0.016). CONCLUSION: Radial inclination, plate distance to joint line, and angle between plate and radius shaft were identified as significant factors associated with improved Mayo Wrist Scores.
