Purpose: To determine the functional outcomes of adolescent athletes treated with arthroscopic marrow stimulation/microfracture for elbow capitellar osteochondritis dissecans (OCD).
Methods: The medical records for all patients younger than 18 years of age with capitellar OCD who underwent arthroscopic treatment at a single institution were retrospectively reviewed. The variables examined included patient characteristics, bone age, pre- and postoperative lesion grade/size and range of motion (ROM), intraoperative lesion grade/size, time to postoperative return to sport, and validated outcome scores.
Results: Twenty patients with 21 treated elbows met the study's inclusion criteria. Three patients were not available for follow-up, leaving 18 of 21 (85.7%) elbows in the final cohort. Mean age and follow-up was 14.1 and 4.4 years, respectively. All 18 elbows were treated with diagnostic arthroscopy, arthroscopic debridement with loose body removal as indicated, and marrow stimulation. Sixteen of 18 (88.9%) elbows returned to sports postoperatively, with 12 of 18 (66.7%) elbows returning to their primary sport at the same level or higher. Overall, there were significant improvements in elbow ROM (132.8°, range 120°-140° postoperatively, compared with 122.1°, range 80°-140° preoperatively) ( = .002) and excellent Quick Disabilities of the Arm, Shoulder and Hand scores (mean 2.3 ± 5.1), as well as Kerlan-Jobe Orthopaedic Clinic Overhead Athlete Shoulder and Elbow scores (mean 94.1 ± 8.7) in those who returned to sports. There was no correlation with outcome or return to sport for preoperative lesion grade/size, bone age, physeal status or open versus arthroscopic treatment.
Conclusions: Arthroscopic debridement and marrow stimulation for capitellar OCD in adolescent athletes leads to improvements in ROM, as well as a high rate of return to sport, and high levels of athletic and daily functional activity during follow-up, regardless of bone age and lesion grade/size at time of surgery.
Level Of Evidence: Level IV, therapeutic case series.

Background: Histologic grade, size, and depth are well-known prognostic factors in soft tissue sarcomas (STS). Small (< 5 cm) and superficial STS generally have an excellent prognosis when treated with appropriate surgery. However, they are often misdiagnosed and mistreated.

Surgical Management and Oncologic Outcomes for Local Retroperitoneal Recurrence of Renal Cell Carcinoma After Radical Nephrectomy.

Introduction: Local retroperitoneal recurrence (RPR) after racial nephrectomy (RN) of renal cell carcinoma (RCC) remains a therapeutic challenge and has a poor prognosis. We aimed to compare the oncological outcomes of patients with RPR treated with RPR surgery or targeted therapy alone and assess the prognostic factors of these patients.
Patients And Methods: This is a retrospective multi-center study of patients with RPR after prior RN treated with or without surgical treatment from 2008 to 2020.
