PCA, CTA, femoral mediolateral lengths (fML), medial femoral anteroposterior lengths (fMAP), lateral femoral anteroposterior lengths (fLAP), distances between the trochlear groove and fMAP (DBTG-fMAP), distances between the trochlear groove and fLAP (DBTG-fLAP), medial posterior condylar cartilage thickness (MPCCT) and lateral posterior condylar cartilage thicknesses (LPCCT) were measured on magnetic resonance imaging (MRI).

Local Prophylactic Teicoplanin Effect on Spinal Fusion Surgery: A Comparative Retrospective Study.

Background:  Surgical site infection (SSI) is one of the most severe complications of spinal fusion surgery that lead to increased morbidity and mortality rates. Prophylactic antibiotic usage is one of the methods that reduce the possibility of SSI in this procedure. The aim of this study was to determine the effect of local subfascial teicoplanin usage on radiologic and functional outcomes and compare it to the effect of vancomycin on surgical outcomes in patients who underwent decompression with posterior instrumentation (DPI) for lumbar spinal stenosis (LSS).

Surgical Management and Outcomes of Patients with Idiopathic Peroneal Spastic Flatfoot: A Retrospective Case Series.

Background: Although tarsal coalition represents the most common cause of peroneal spastic flatfoot, its existence cannot be verified in several cases. In some patients with rigid flatfoot, no cause can be detected after clinical, laboratory, and radiologic examination, and the condition is called idiopathic peroneal spastic flatfoot (IPSF). This study aimed to present our experience with surgical management and outcomes in patients with IPSF.

Plate fixation after lengthening with an external fixator in patients with achondroplasia : A comparative study between two centers.

Background: This study compared internal fixation with a plate after lengthening (PAL) with an external fixator with the conventional method (CM) in terms of radiologic and clinical outcomes in the lower extremities of patients with achondroplasia.

Methods: In this study 20 patients (50 lower extremity long bones) who underwent PAL or CM were divided into 2 cohort groups. The amount of lengthening, percentage lengthening, external fixator index (EFI), external fixator time, Li regeneration index, complication rate, and knee range of motion (ROM) were compared between the groups.

Antero-posterior axis of the tibia is a better landmark for tibial component rotation in Oxford medial unicompartmental knee arthroplasty.

Background: This retrospective study compares tibial component rotations and radiological and functional outcomes in patients who underwent Oxford medial unicompartmental knee arthroplasty (UKA), using the antero-posterior (AP) tibia axis or anterior superior iliac spine (ASIS) as the landmarks for the direction of the vertical cut.

Methods: A total of 86 patients, who underwent Oxford medial UKA were divided into 2 groups, each consisting of 43 patients, according to the use of AP axis (group I) or ASIS (group II) as landmarks for the rotation of vertical tibial cut and compared for the radiological and functional outcomes. Tibial component rotations (α-angle), involvement of the posterior cruciate ligament (PCL) fossa, and instant bearing position (IBP) were measured on computed tomography (CT) images.

Subacromial Spacer Implantation During Arthroscopic Partial Repair in Patients With Massive Irreparable Rotator Cuff Tears Provides Satisfactory Clinical and Radiographic Outcomes: A Retrospective Comparative Study.

Purpose: To compare the clinical and radiographic outcomes of partial rotator cuff repair (RCR) with and without implantation of a biodegradable subacromial spacer in the treatment of symptomatic irreparable massive rotator cuff tears (MRCTs).

Methods: Patients with MRCT who underwent arthroscopic partial repair alone (PR) or combined with subacromial spacer augmentation (PRS) were included. Patient-reported outcomes, including visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES), and Constant scores in addition to range of motion (ROM) were collected preoperatively and at the final follow-up.

The effect of onlay cortical fibula strut grafts on biomechanical features of Vancouver type B1 periprosthetic femoral fractures.

Objective: This study aimed to investigate biomechanically the effects of onlay fibula grafts on Vancouver Type B1 Periprosthetic Femoral Fractures (PPFs).

Methods: Vancouver Type B1 PFF models were created in 25 fourth-generation synthetic femurs and fixed with locking plates using bicortical, unicortical screws, and cables. While no graft was used in group 1, onlay fibula grafts were placed anteriorly in group 2 and medially in group 3.

Sagittal Patellar Offset Ratio Can Be a Predictor of Anterior Knee Pain after Primary Total Knee Arthroplasty without Patella Resurfacing.

Background: Anterior knee pain (AKP) is an issue that persists even after successful total knee arthroplasty (TKA). In some patients, reasons for AKP occurrence are known, but it is unexplained in some others despite the patellofemoral joint being thought to be the main focus of pain. We investigated the relationship between unexplained AKP and the patellofemoral joint in the sagittal plane after primary TKA.

Comparison of the Functional and Radiological Outcomes of Single- and Two-Stage Bilateral Open Wedge High Tibial Osteotomy.

Purpose: This study compared the functional and radiological outcomes and complications of single- (SS) and two-stage (TS) bilateral high tibial osteotomy (HTO).

Methods: From 2014 to 2018, 48 patients underwent bilateral HTO surgery for osteoarthritis. The outcomes of SS in 28 knees and TS in 32 knees were compared using the Knee Injury and Osteoarthritis Outcome Score (KOOS) and Oxford Knee Score (OKS) as functional outcomes, and the medial proximal tibial (MPTA), hip-knee-ankle (HKA), tibial slope (TSA) angles, and mechanical axis deviation (MAD) as radiological outcomes.

Two-surgeon simultaneous bilateral total knee arthroplasty does not provide poor prosthetic alignment : A prospective randomized controlled study.

Purpose: Two-surgeon, simultaneous bilateral total knee arthroplasty (TKA) is considered as an unpredictable, complex procedure in terms of its radiographic and functional outcomes because of different surgeons and teams, and too many instruments and hands in a narrow space. We compared radiological and functional results of simultaneous bilateral TKA and single-surgeon sequential bilateral TKA.

Methods: The 136 participants with a minimum of 24 months follow-up were prospectively randomized into 2 groups: two-surgeon bilateral TKA and single-surgeon bilateral TKA.

Comparison of tapered-wedge short and standard-length femoral stems in single-stage bilateral direct anterior total hip arthroplasty.

Purpose: This study was performed to compare short and standard-length tapered-wedge-type femoral stems in single-stage bilateral total hip arthroplasty (THA) through a direct anterior approach (DAA).

Materials And Methods: The patients were divided into two groups according to their femoral stem types as short tapered-wedge stem and standard-length tapered-wedge stem groups. Outcome parameters were the surgical time, estimated blood loss (EBL), length of stay (LOS), thigh pain, Harris Hip Score (HHS), and visual analog scale (VAS) score clinically, and canal fill ratio (CFR), coronal plan alignment of the stems, subsidence, and postoperative leg length difference (LLD), radiologically.

Methods: 4877 Patients with a minimum follow-up of 90 days were included to investigate the effect of dressing on the PJI occurring within 3 months of surgery.

Onlay fibula autografting technique and its comparison with cortical allograft for the reconstruction of periprosthetic bone defects around the femur.

Background: Bone defect around the femur related to revisions or periprosthetic fractures (PFF) is an issue. We present a bone defect reconstruction technique in femoral revisions and/or PFF using fibula autograft and compared our radiological and clinical results to that of allograft.

Methods: A total of 53 patients who underwent revision hip arthroplasty and/or PFF fixation with the use of cortical fibula autograft (FG group) or cortical allograft (CG group) were evaluated.

Does performing total joint arthroplasty in the afternoon or evening increase the risk of prosthetic joint infection?

Purpose: Does performing total joint arthroplasty in the afternoon or evening increase the rate of early prosthetic joint infection and the likelihood of early prosthetic joint infection?

Methods: We evaluated patients retrospectively, who underwent primary total hip (THA) or knee arthroplasty (TKA) between January 2016 and December 2019, met the inclusion criteria and had at least 90 days of follow-up. Patients were divided into two groups. Group I consisted of patients whose surgeries had been started and finished before 14:00, and group II included patients whose surgeries started after 14:01.

Safety of one-stage bilateral total knee arthroplasty -one surgeon sequential vs. two surgeons simultaneous: a randomized controlled study.

Purpose: This study aimed to examine the complications by comparing two surgeons simultaneous bilateral total knee arthroplasty (two-surgeon bilateral TKA) to one surgeon sequential bilateral total knee arthroplasty (single-surgeon bilateral TKA).

Methods: Two hundred forty-six participants were prospectively randomized into two groups: two-surgeon bilateral TKA and single-surgeon bilateral TKA. While two surgeons performed simultaneous total knee arthroplasty in the two-surgeon bilateral TKA group, one surgeon performed sequentially in the single-surgeon bilateral TKA group.
