Background: There is still a lack of clinical data in arthroscopic treatment for treating multiple ligament injuries. This study aims to evaluate the clinical outcomes of patients with multiple ligament injuries undergoing treatment based on the classification stage and type of injury.
Methods: A prospective, clinical trial on multiple ligament injuries was planned, which included 95 patients (58 men and 37 women; age: 42.8 ± 11.9 [range, 18-63] years) from October 2017 to June 2018. Injuries were classified into three stages (emergency stage < 24 h; acute stage: 24 h to 3 weeks, and chronic stage: > 3 weeks) and six types (KD I-VI) based on injuries time and structures, which indicated appropriate treatments. The clinical outcomes were evaluated at 2, 4, 6, 8, and 12 weeks and at 6, 9, 12 months and 24 months after surgery. The final choices in efficacy index included International Knee Documentation Committee (IKDC) score, Lysholm score, visual analog scale (VAS) score, and range of motion.
Results: During the follow-up, all patients exhibited statistically significant functional improvement in the injured limb compared with their preoperative situation. The mean postoperative scores of acute stage patients at 2-year follow-up were IKDC subjective score, 77.54 ± 11.53; Lysholm score, 85.96 ± 9.39; Tegner score, 4.13 ± 1.08; and VAS score, 1.21 ± 0.76. The mean postoperative scores of chronic stage patents at 2-year follow-up were IKDC subjective score, 74.61 ± 12.38; Lysholm score, 81.71 ± 10.80; Tegner score, 3.96 ± 1.14; and VAS score, 1.71 ± 0.60. The IKDC subjective score, Lysholm score, and Tegner score were significantly improved (P < 0.01) and the VAS score was significantly decreased (P < 0.01) at 2-year follow-up. Regarding the multiple ligament injuries classification, patients with more structural damage in stages V and VI showed less progress in functional recovery than those in stages I-IV.
Conclusions: This new classification with three stages and six types helps to identify the severity of injury and plan the management effectively. The outcomes were encouraging and the subjective functional results showed significant improvement at 2-year follow-up.

Non-contact anterior cruciate ligament (ACL) rupture is a common serious orthopaedic disease in humans and dogs. Familial risk has been recognized in both species but interactions between genetic effects and environmental risk are not understood. We investigated ACL rupture heritability, genetic architecture, selection pressure, sharing of risk genes and biological pathways, and polygenic risk score (PRS) prediction of disease risk.

Case: A 41-year old man fell from height sustaining displaced radial shaft and ulnar styloid fractures underwent open reduction internal fixation of the radius with early recognition of a radiocapitellar dislocation and longitudinal forearm instability in the early postoperative period. Revision surgery was performed 13 days postoperatively involving annular ligament reconstruction, elbow spanning external fixation, and distal radioulnar joint stabilization. Favorable functional and radiographic outcomes are shown at 1-year follow-up.

The medial patellofemoral complex provides the primary static restraint to lateral patellar translation and is composed of the medial patellofemoral ligament and medial quadriceps tendon femoral ligament. Multiple techniques including medial patellofemoral ligament and/or medial quadriceps tendon femoral ligament reconstruction have demonstrated good results; however, modification of the femoral fixation technique is required for skeletally immature patients or revision cases in which anatomic bony fixation on the femur is not possible. This technique describes an all-soft-tissue procedure for single-bundle medial patellofemoral complex reconstruction in which the graft is fixed on the adductor tendon while using the medial collateral ligament as a distalizing pulley, for anatomic and isometric recreation of the native ligament.

Purpose: (1) To evaluate the incidence and combination types of concomitant malleolar and fibular fractures in patients with distal spiral tibial shaft fractures. (2) To evaluate the risk factors for concomitant malleolar fractures in patients with distal spiral tibial shaft fractures.
Methods: A retrospective review was performed on 64 cases of surgically treated distal spiral tibial shaft fractures with complete radiographs and computed tomography (CT) scans.

Purpose: To use a large nationwide administrative database to directly compare usage, complications, and need for revision stabilization surgery after medial patellofemoral ligament reconstruction (MPLFR), tibial tubercle osteotomy (TTO), and combined MPFLR and TTO (MPFLRTTO).
Methods: The PearlDiver Mariner database was queried for all reported cases of MPLFR, TTO, and combined MPFLRTTO performed between 2010 and 2020 using Current Procedural Terminology codes. Subsets from those cohorts with laterality-specific , , codes for patellar instability were used to evaluate 2-year incidence of infection, stiffness, fracture, and revision stabilization with MPFLR and/or TTO.
