Background: Although tension-band wiring is the most widely used technique to fix patellar fractures, metal implant-related complications including implant failure and postoperative pain are very common and additional procedures are often necessary to treat the complications. The purpose of this study is to evaluate a totally metal-free technique using a transosseous suturing method and to compare it with the traditional fixation technique.
Method: A total of 25 patients (mean age of 59.60 years) with displaced patellar fractures treated by a transosseous suturing technique were compared with a 1:1 matched historical control group that underwent modified tension-band-wire fixation. Union time, union rate, operation time, number of procedures, mean hospitalisation days and complications were compared between cases and controls.
Results: Union time (8.43 ± 2.92 vs. 8.64 ± 2.82 weeks) and operation time (69.00 ± 19.31 vs. 64.89 ± 14.27 min) were not different between the two groups. Mean hospitalisation days (4.04 ± 1.40 vs. 5.76 ± 1.50 days; P<0.001), number of procedures and the frequency of complications were significantly lower in the transosseous suturing group.
Conclusion: The transosseous suturing technique is safe and effective in the transverse or comminuted fractures of the patella. The complication rate is significantly lower than with the tension-band-wiring technique.

Objective: Repositioning and fixation of the posterior septal angle (PSA) relative to the anterior nasal spine (ANS) is a well-known maneuver performed during rhinoplasty. Suture techniques through the periosteum along with transosseous drilling through the spine are the two most common fixation methods. We report on how nasal airway patency varies as a function of technique and patient demographic factors.

Background: For complete disruption of the posterolateral corner (PLC) structures, operative treatment is most commonly advocated, as nonoperative treatment has higher rates of persistent lateral laxity and posttraumatic arthritis. Some studies have shown that acute direct repair results in revision rates upwards of 37% to 40% compared with 6% to 9% for initial reconstruction. In a recent study assessing the outcomes of acute repair of PLC avulsion injuries with 2 to 7 years of follow-up, patients with adequate tissue were shown to have a much lower failure rate than previously documented.

Patellar dislocation is a common knee injury, with concomitant pathoanatomical risk factors that synergistically interact and predispose to patellofemoral instability. Medial patellofemoral ligament (MPFL) reconstruction has demonstrated significant potential in the re-establishment of MPFL anatomic and biological function, with low patellar redislocation rates. Although many techniques for MPFL reconstruction have been developed, challenges such as patella fractures and high costs persist.

This article aims to present a comprehensive technical note detailing our preferred treatment approach for tibial tuberosity avulsion fractures in the adult and elderly populations, particularly in scenarios characterized by low tissue quality and limited bone stock. Existing literature on this fracture type is scarce, with many described techniques relying on optimal bone quality for effective screw fixation of the tibial tuberosity. Various methods for tibial tuberosity avulsion fixation include K-wires, cannulated screws, staples, tension bands, suture anchors, and in select cases, direct transosseous sutures.

Patellar tendon injuries, although less frequent than other knee injuries, can have a profound impact on knee function, often leading to significant disability. Among the various surgical techniques employed to repair these injuries, the suture anchor and transosseous tunnel methods are the most commonly used. This systematic review and meta-analysis compares the biomechanical properties and functional outcomes of these two repair techniques.
