Removal of cement-augmented screws in distal femoral fractures and the effect of retained screws and cement on total knee arthroplasty: a biomechanical investigation
ConclusionThe screw removal torque during implant removal surgery does not significantly differ between augmented and nonaugmented screws. In the augmented screw group, significantly more screws failed. To overcome this, the use of solid screws in holes B, C, and G can be considered. Additionally, it is possible to implant a femoral component for knee arthroplasty that retains the initial anchorage and does not suffer from interference with broken screws and/or residual cement.Level of Evidence 5 (Source: Journal of Orthopaedics and Traumatology)

Risk factors for refracture of the femoral shaft in children after removal of external fixation
ConclusionsFemoral shaft refracture is relatively common in children treated with external fixation. Because of the limited number of cases in this study, we cautiously concluded that the PCCF classification type 32-D/4.2 and L2/L3 ratio were independent risk factors for femoral shaft refracture in these patients.Level of evidenceIV (Source: Journal of Orthopaedics and Traumatology)

Arthroscopic rotator cuff repair in patients over 70  years of age: a systematic review

Custom-made reverse shoulder arthroplasty for severe glenoid bone loss: review of the literature and our preliminary results
AbstractThe treatment of severe glenoid bone loss in shoulder arthroplasty represents a challenge, and the results of current prosthetic designs with only glenoid fixation still remain unsatisfactory. In the past decade, customized glenoid prostheses have been developed to address severe glenoid arthritis and in the revision setting. In this review, we analyzed the current surgical options, the classification limits, past literature evidence, and our preliminary results of 6 patients (3 male, 3 female) treated with a reverse implant and custom-made glenoid implant (ProMade; LimaCorporate, Italy). Computer analysis of the r...

Arthrofibrosis after total knee arthroplasty: patients with keloids at risk
ConclusionPatients with keloids have increased odds risk of arthrofibrosis following primary TKA. These patients are subsequently at a higher odds risk of undergoing the procedures necessary to treat arthrofibrosis, such as MUA and LOA. Future studies investigating confounding factors such as race, prior surgery, range of motion, and postoperative recovery are needed to confirm the association of keloid diagnosis and arthrofibrosis following primary TKA demonstrated in this study.Level of EvidenceLevel III retrospective comparative study.

Hip fracture patients admitted to hospital on weekends are not at increased risk of 30-day mortality as compared with weekdays
ConclusionThe evidence for a ‘weekend effect’ in patients with a hip fracture is absent in this study. However, we have shown other factors that are associated with increased mortality such as increased age, male sex and higher ASA grade.Level of evidenceLevel 3.

Fracture –dislocations of the forearm joint: a systematic review of the literature and a comprehensive locker-based classification system
ConclusionsAll injury patterns may be previously identified using an alphanumeric code. This might avoid confusion in forearm fracture –dislocations nomenclature and help surgeons with detection of lesions, guiding surgical treatment.Level of evidenceV.

Satisfactory mid-term outcomes of condylar-constrained knee implants in primary total knee arthroplasty: clinical and radiological follow-up
ConclusionCCK implants in primary TKA with major coronal deformities and/or intraoperative instability provide good midterm survivorship, comparable with less constrained implants. In specific cases, CCK implants can be considered a viable option with good clinical and radiographic outcomes. However, a higher degree of constraint should be used cautiously, leaving the first choice to less constrained implants.Level of evidence Therapeutic study, level IV.

Systematic review of clinical practice guidelines for adults with fractures: identification of best evidence for rehabilitation to develop the WHO ’s Package of Interventions for Rehabilitation
ConclusionThe selected CPGs on management of distal radius and femoral/hip fracture include few recommendations regarding rehabilitation, with overall low to very low quality of evidence and weak/conditional strength of recommendation. Moreover, several gaps in specific rehabilitative topics occur. Further high-quality trials are required to upgrade the quality of the available evidence.Level of evidenceLevel 1.

The necessity of routine postoperative laboratory tests after total hip arthroplasty for hip fracture in a semi-urgent clinical setting
ConclusionsThis study demonstrated a high incidence of abnormal postoperative laboratory tests and a significant clinical intervention rate in patients who underwent THA for hip fracture in a semi-urgent clinical setting, which indicates that routine laboratory tests after THA for hip fracture are still necessary for patients with certain risk factors.Level of EvidenceLevel III.Trial registration Clinical trial registry number ChiCTR1900020690.

Acute primary repair of extraarticular ligaments and staged surgery in multiple ligament knee injuries
ConclusionsIn this series, all patients returned to their activities of daily living and preinjury occupation levels. Acute primary repair of extraarticular ligaments provides essential knee stability without varus/valgus instability and may reduce the need for subsequent cruciate ligament reconstruction.Level of evidenceLevel IV, retrospective observational study.

Unicompartmental knee arthroplasty, an enigma, and the  ten enigmas of medial UKA
AbstractUnicompartmental knee arthroplasty (UKA) is a bone- and ligament-sparing alternative to total knee arthroplasty in the  patients with end-stage single-compartment degeneration of the knee. Despite being a successful procedure, the multiple advantages of UKA do not correlate with its usage, most likely due to the concerns regarding prosthesis survivability, patient selection, ideal bearing design, and judicious u se of advanced technology among many others. Therefore, the purpose of this study is to review and summarize the debated literature and discuss the controversies as “Ten Enigmas of UKA.” (Source: Jo...
