The ideal graft choice should recreate normal anatomy and biomechanics, allow for rapid return to play and have minimal harvest-site morbidity. The purposes of this study were to compare donor-site morbidity in all-soft-tissue quadriceps autograft vs. hamstring autografts based on Hacken et al.'s ACL Donor-Site Morbidity Questionnaire (32,587,874) and to assess the role played by external factors such as sex, mood, activity level and smoking status. <b>Materials and Methods:</b> We performed a retrospective analysis of our patients' records to identify individuals who were 30 years old or younger at the time of surgery and underwent ACL reconstruction using the anteromedial portal technique, without any additional treatments for ligament or meniscal injuries. At 12 months postintervention, donor-site morbidity was evaluated using the ACL donor-site morbidity questionnaire by Hacken et al. (2020).

Statistically significant results were also found in favour of QT when comparing numbness and size of numbness at the donor site and self-perceived muscle atrophy. Female sex and low mood have been found to impact donor-site morbidity negatively although larger samples are necessary to confirm this association.

This study compares the clinical outcomes of using the shortest effective cephalomedullary nails (170 mm) to various short length (200 mm and 240 mm), focusing on Asian patients. <b>Methods:</b> In this randomized controlled trial, 50 patients aged 50 years or older with unstable intertrochanteric fractures (AO types 31A2-3) were randomly assigned to two groups. The shortest-nail group (<i>n</i> = 25) received a 170 mm cephalomedullary nail, while the control group (<i>n</i> = 25) received either a 200 mm or 240 mm nail based on patient height.

Intramedullary nailing is a widely used treatment, though optimizing biological healing remains essential. Platelet-rich plasma (PRP), containing abundant growth factors, has been suggested as a therapeutic aid to enhance fracture healing. <b>Methods:</b> A randomized controlled trial was conducted, including 32 patients diagnosed with acute AO 42-C3 pure diaphyseal tibial fractures. Patients were randomized into two groups: 16 received PRP injections, while 16 received normal saline solution (NSS) injections as a control. The primary outcome, cortex-to-callus ratio, was assessed via radiographs over a 6-month follow-up.
