3D assessment of graft malposition after ACL reconstruction: Comparison of native and 11o'clock ligament orientations
Femoral tunnel malposition makes up the majority of technical failures for ACL reconstructive surgery. The goal of this study was to develop adolescent knee models that accurately predict anterior tibial translation when undergoing a Lachman and pivot shift test with the ACL in the 11o ’clock femoral malposition (Level of Evidence: IV).

The effect of weight-bearing positions on coronal lower limb alignment: A systematic review
The coronal alignment of the lower limb is generally accepted as a major determinant of surgical outcome in total knee arthroplasty (TKA). To achieve the ideal post-operative alignment, surgeons need to be aware of the influence that weight-bearing positions have on the final knee alignment.Therefore, this review aims to define the effect of varying weight-bearing positions on the coronal alignment of the lower limb. We hypothesized that a coronal alignment deformity increases with loading. (Source: The Knee)

Decision regret following opening wedge high tibial osteotomy: Older age as a risk factor
Understanding risk factors that can predict decision regret after surgical procedures can potentially increase the quality of patient decision making and reduce decision regret after opening wedge high tibial osteotomy (OWHTO). The purpose of the present study was to identify the risk factors that predict the likelihood of decision regret after OWHTO. (Source: The Knee)

Low local curvature index and history of previous surgery are risk factors for revision in focal metallic inlay implants
Focal chondral defects are debilitating lesions with poor healing potential. Focal metallic inlay implants were developed as a salvage procedure, whose reoperation causes and risk factors for revision are still debatable. The aim of this study is to analyze the local subchondral curvature matching of focal metallic inlay implants and its effects on survival and clinical results. (Source: The Knee)

Concurrent validity of the 2-and 6-minute walk test in knee osteoarthritis
The objective of our study was to analyze the concurrent validity of the 2-Minute Walk Test (2MWT) for patients with knee osteoarthritis compared to the 6-Minute Walk Test (6MWT). (Source: The Knee)

Using a target as external focus of attention results in a better jump-landing technique in patients after anterior cruciate ligament reconstruction – A cross-over study
Improving jump-landing technique during rehabilitation is important and may be achieved through different feedback techniques, i.e., internal focus of attention (IF) or external focus of attention using a target (EF). However, there is a lack of evidence on the most effective feedback technique after anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to investigate the potential difference in jump-landing techniques between IF and EF instructions in patients after ACLR. (Source: The Knee)

Patellofemoral arthroplasty conversion to total knee arthroplasty: An updated retrieval analysis and clinical outcomes
A prior retrieval analysis found high rates of infection after conversion of PFA to TKA, but was limited by a small sample size. The purpose of this study is to perform a retrieval analysis with clinical correlation on an expanded group of patients to better understand conversion of PFA to TKA. (Source: The Knee)

Combined press-fit and extracortical fixation in patellar tendon anterior cruciate ligament reconstruction results in reliable graft fixation and early bone block incorporation
Anterior cruciate ligament (ACL) reconstruction with bone –patellar-tendon–bone (BPTB) autograft has the potential biological advantage of direct bone-to-bone healing over soft tissue grafts. The primary aim of this study was to investigate possible graft slippage and therefore fixation strength in a modified BPTB autograft technique with suspensory fi xation on both sides for primary ACL reconstruction until bony integration takes place.

Three-dimensional joint surface orientation does not correlate with two-dimensional coronal joint line orientation in knee osteoarthritis: Three-dimensional analysis of upright computed tomography
Knee osteoarthritis (OA) is the most common form of arthritis, affecting around 30% of adults over 60 years old [1]. The causes of knee OA have traditionally been divided into biological and mechanical factors, with lower limb malalignment representing one of the mechanical factors [2]. Alignment parameters based on two-dimensional (2D) coronal radiography, such as the Mikulicz line and femorotibi al angle (FTA), have been widely used for the diagnosis of, selection of treatment strategies for, and pre- and postoperative evaluations of OA [3,4].

Tumoral calcinosis of the knee treated with open, physeal sparing iliotibial band ACL reconstruction
We present a case of tumoral calcinosis in a 13-year-old male with a history of a 12q13.11 genetic deletion. Surgical resection of the tumor necessitated resection of the ACL in its entirety with curettage and adjuvant therapy to the lateral femoral notch, which resulted in ligamentous instability and bony structural incompetency at the femoral insertion. Given the patient ’s radiographically-apparent skeletal immaturity, and lack of reliable bony architecture to accommodate a femoral ACL tunnel, ACL reconstruction was performed using a physeal-sparing technique.

Comparison of CT and EOS in assessing coronal lower limb alignment when planning total knee arthroplasty
The ability to accurately measure lower limb alignment is essential in pre-operative planning and post-op assessment of total knee arthroplasty (TKA) and deformity correction surgeries. The popularity of technologies that allow precise component positioning [1,2] and interest in novel alignment philosophies [3] highlight the need for accurate assessment of lower limb alignment when planning TKA.

Three-dimensional adipose-derived stem cell spheroids exert potent therapeutic effects on rat femur osteochondral defects
Osteochondral defects in the articular tissue have a poor capacity for spontaneous repair owing to insufficient blood supply [1]. Therefore, several advanced treatments have been developed, such as osteochondral transplantation, autologous chondrocyte transplantation, and administration of cultured cartilage and stem cells [2].
