Unicompartmental knee arthroplasty (UKA) is a surgical alternative to total knee arthroplasty (TKA) for the treatment of unicompartmental osteoarthritis. However, data on the failure rate of UKA show a 7-year survival rate of 74%, which is significantly lower than that of TKA (92%). Although patients' own factors increase the risk of failure, such as younger patients and higher body mass index (BMI) may increase the risk of UKA failure, surgical technical errors have been considered as important risk factors for early failure. In UKA, it is challenging to achieve optimal prosthetic alignment and overhang (overhang). The tibial prosthesis should be sized and implanted in a manner that minimizes soft tissue irritation, and a medial tibial overhang of more than 3 mm has been shown to be a significant risk factor for decreased Oxford Knee Score (OKS) and increased pain. The primary objective of this study was to evaluate the overall clinical and imaging outcomes of UKA.

Humeral stem fractures (HSF) are relatively common, accounting for approximately 1% to 5% of all fractures. The annual incidence is 13 to 20 per 100,000 people and has been found to increase with age.HSF has a bimodal age distribution, with the first peak occurring in men between 21 and 30 years of

Choice of internal fixation versus joint replacementAt present, it is generally believed that hollow nail internal fixation for femoral neck fracture has the advantages of short operation time, little trauma and low cost, but most elderly patients are accompanied by osteoporosis, so the stability of

Intertrochanteric fracture of the femur, also known as intertrochanteric fracture, is an extra-articular capsule fracture. The main manifestations of intertrochanteric fracture are significant local pain and swelling, extensive ecchymosis, inability of the patient to stand or walk, significant short

What is a metacarpal fracture?The metacarpals are the long bones of the hand. Each hand has five metacarpal bones, one for the thumb and one for each finger. A metacarpal is a crack or break in one of these bones.What causes metacarpal fractures?These fractures are usually caused by a fall or a dire
