Article Abstract
The aim of this study was to determine if the type of reamer used in tibial tunnel creation during anterior cruciate ligament (ACL) reconstruction influences the dimensions of the tunnel's outer aperture. Tibial tunnels were created in tibial saw bones by reaming over a guidewire using an 8 mm acorn or fluted reamer in an antegrade manner. Reaming was aimed either in line with the guidewire, or with 10-degree inferior/superior deviation in relation to the wire. The shape and size of the outer aperture of the tibial tunnel were compared between the two reamers. When using the acorn reamer, a 10-degree deviation in relation to the guidewire resulted in minimal change in outer aperture length (mean 13.6 vs. 15.6 mm, = 0.11) and width (11.6 vs. 11.1 mm, = 0.51). However, when using the fluted reamer, although the aperture width showed no substantial change with reamer/guidewire deviation (11.4 vs. 11.2 mm, = 0.71), the mean length almost doubled (14.7 vs. 28.1 mm, = 0.002). The use of a fluted reamer when reaming the tibial tunnel creates a distal aperture which is inconsistently sized, larger, and of oblong shape compared with an acorn-shaped reamer. This should be taken in consideration when using a fluted reamer for creating the tibial tunnel in ACL reconstruction.

Purpose: Modifying interference screw composition may ensure better osteoconductive properties in order to reduce tunnel enlargement after anterior cruciate ligament (ACL) reconstruction. The primary and secondary purposes were to evaluate tunnel and screw volume changes in poly-L-lactide acid (PLLA) and poly-D-lactic acid + hydroxyapatite + β-tricalcium phosphate (PLDLA+) screws. The tertiary purpose was to compare patient reported- and functional outcomes between PLLA and PLDLA+ group.

Purpose: To assess the functional and subjective outcomes of combined anterior cruciate ligament reconstruction (ACLR) and lateral meniscal root tear (LMRT) repair. Additionally, to compare the use of an independent tunnel for LMRT repair with the ACL bone tunnel technique and to assess the failure rates of LMRT repair to isolated ACLR.
Methods: Patients who underwent primary ACLR and concomitant LMRT repair from May 2017 to May 2022 at Capio Artro Clinic, Stockholm, Sweden, were retrospectively identified and matched 1:3 (age, sex and graft type) with patients who underwent isolated ACLR during the same period.

Objective: Anatomical reconstruction of the posterior cruciate ligament (PCL) with suture tape augmentation to enhance primary stability.
Indications: Acute or chronic PCL ruptures, either isolated or as part of multiligamentous injuries, in cases of symptomatic instability or failure of conservative treatment.
Contraindications: Fixed posterior drawer, active infection, bony avulsion.

Introduction: Tunnel widening following anterior cruciate ligament (ACL) reconstruction remains a significant clinical concern. Polyether ether ketone (PEEK) screws offer favorable biomechanical properties and MRI compatibility; however, they lack osteoconductivity, which may contribute to tunnel widening. This study investigated whether hydroxyapatite (HA)-coated polyether ether ketone (PEEK) screws reduce tibial tunnel widening compared to uncoated PEEK screws, considering the osteoconductive properties of HA.

Background: Meniscal extrusion has been reported to be present in >50% of knees after medial meniscus root repair. Meniscal extrusion has also been reported to be a risk factor for the progression of osteoarthritis and poorer patient-reported outcomes by impairing the ability of the meniscus to absorb hoop stress.
Purpose: To determine whether the addition of a centralization suture to 2-tunnel transtibial root repair reduces postoperative medial meniscal extrusion in patients with type 2 posterior medial meniscus root (PMMR) tears.
