Purpose: Younger age and steep posterior tibial slope (PTS) have been reported as risk factors for graft failure after anterior cruciate ligament reconstruction (ACLR). Few studies have evaluated these risk factors simultaneously in a large cohort of patients undergoing double-bundle ACLR (DB-ACLR). Therefore, this retrospective study aimed to simultaneously investigate known risk factors such as PTS and age in DB-ACLR, determine their thresholds and calculate odds ratios (ORs).

Article Synopsis
  • The study aimed to compare the incidence of post-operative meniscal cysts in patients who had meniscal repair surgery with and without the use of all-inside suture devices, analyzing data from 227 knees.
  • Results showed that the group using all-inside devices (Group SA) had a 9% incidence of cysts, while the group that didn’t use these devices (Group NA) had a 7% incidence, with no significant difference between the two.
  • The type of suture device did not appear to significantly affect cyst formation or symptoms, indicating that the choice of device may not be a critical factor in meniscal repair outcomes.

Article Synopsis
  • - A study investigated if certain factors contribute to increased anteroposterior (AP) laxity over time in patients who underwent anterior cruciate ligament reconstruction (ACLR) using hamstring tendons.
  • - Out of 151 patients, 21% showed significant increases in AP laxity from the 5-month mark to 1 and 2 years post-surgery, with the affected group being older and having longer surgical waiting times.
  • - Despite the observed increase in laxity in some patients, their clinical outcomes measured by the Knee injury and Osteoarthritis Outcome Score (KOOS) at 2 years were similar to those who did not experience laxity changes.

Introduction: Although intramedullary screw fixation likely leads to successful union of Jones fractures compared to that of nonoperative treatments, bony union disorder after surgical treatment remains to be elucidated.

Methods: Intramedullary screw fixation was performed for the surgical treatment of proximal fifth metatarsal stress fractures in this series. Between January 2008 and December 2019, the feet of 222 patients were investigated regarding the effective factors for postoperative bony union between the normal union group and the bony union disorder group according to the patients' physical status, radiological assessment, and screw size.

Background: Return to sports is one of the important reasons why athletes with an anterior cruciate ligament (ACL) injury undergo surgery. There are few reports on return to sports among adult amateur athletes (individuals older than the college age who participate in competitive sports). This study aimed to investigate the return of adult amateur athletes to competitive sports 1 year after ACL reconstruction and to identify the indicators for return to competitive sports.

Surgery with autologous bone grafting for proximal fifth metatarsal diaphyseal stress fracture has a potential to decrease nonunion, but it is not performed widely as the primary surgery because of donor-site morbidity. We have devised and performed a less invasive surgical procedure with autologous bone grafting and aimed to investigate the clinical and radiologic outcomes of this procedure. The data for 73 patients who underwent primary intramedullary screw fixation with autologous bone grafting from the fifth metatarsal base for proximal fifth metatarsal diaphyseal stress fractures were investigated retrospectively.

Mini-incision surgical procedures in our institution have been developed by decreasing the total skin incision length from the original mini half-Bunnell tendon repair technique. We hypothesized that the mini-incision, or minimum invasive Achilles tendon repair technique, would promote the tendon healing process leading to better outcomes and a reduced complication rate compared to the conventional open repair. The study sought to determine the more optimal method by comparing 44 mini-incision sutures to the 99 sutures in the original open Achilles tendon repairs.

Background: Intramedullary screw fixation is considered the standard treatment for proximal fifth metatarsal stress fractures. Low-intensity pulsed ultrasound (LIPUS) is a well-known bone-healing enhancement device. However, to the best of our knowledge, no clinical study has focused on the effect of LIPUS for postoperative bone union in proximal fifth metatarsal stress fractures.

Arthroscopic suture repair for a radial tear at the posterior horn of the lateral meniscus poses a technical procedure for surgeons. We describe an all-inside repair technique using all-inside meniscal repair devices without adding any accessory portals. This simple technique provides precise reduction and stabilization of the meniscus by pinching 2 all-inside vertical sutures consecutively across the tear site.

Purpose: To assess the clinical outcomes comparing rectangular bone-tendon-bone (BTB) grafts and double-bundle hamstring tendon (HM) grafts used for anatomic anterior cruciate ligament (ACL) reconstruction in young female athletes.

Methods: From January 2014 to November 2017, young female athletes 20 years or younger who underwent primary ACL reconstructions by a single surgeon were identified. Patients with concomitant injuries, not being a regular sports participant, the existence of contralateral ACL reconstruction, and who did not have a minimum of 1-year follow-up were excluded.

Background: Despite the fact that many surgeons perform partial capsular detachment from the anterosuperior aspect of the acetabulum to correct acetabular deformities during hip arthroscopy, few studies have focused on whether these detachments influence hip joint stability. The aim of this study was to investigate the capsular attachment on the anterosuperior aspect of the acetabulum. We hypothesized that the attachment on the inferior aspect of the anterior inferior iliac spine (AIIS) is wide and fibrocartilaginous and might have a substantial role in hip joint stability.

Osteochondritis dissecans (OCD) of the femoral head is an unusual cause of hip pain. It can be associated with other intra-articular pathologies including: acetabular labral tears or bone deformities such as Legg-Calve-Perthes Disease (LCPD). In this article, we propose a modern surgical technique using an arthroscopic antegrade and retrograde osteochondral autologous transplantation (OAT) procedure for assessing and treating OCD lesions of the femoral head.
