Radiography is the primary modality for routine follow-up, but MDCT has become the standard for optimized assessment of postoperative implants, and MRI plays a major role in the diagnosis of complications such as infection and soft-tissue lesions.

Bipolar radiofrequency ablation is a safe modality in treatment of chondral lesions.

This study suggests that there is a learning curve with the use of sensor-guided assessment in TKA in achieving knee balance; however, the differences noted between initial and final groups were small and may not be of clinical significance.

BackgroundDespite debate over the role of patellar resurfacing in total knee arthroplasty, many surgeons feel it decreases re‐operation rates and anterior pain, and an increasing number are adopting resurfacing. This study compares intra‐operative characteristics of different patellar implants to assist surgeons in gaining better understanding of these implants.MethodsThe three most commonly used patellar implants (inset, onlay round and onlay oval) were allocated randomly to 120 patients undergoing total knee arthroplasty. We compared the groups in terms of implant size, bone coverage, lateral underhang (uncovered lateral facet) and need for partial lateral facetectomy. We also compared the patient‐reported outcome measures between the groups at 6 months post‐operatively.ResultsThe inset, onlay round and onlay oval designs had bone coverage of 48.5%, 65.9% and 85.9%, respectively (P < 0.01). Similarly, the onlay‐oval implant was found to have the smallest lateral underhang of all three designs (inset 11.6 mm; onlay round 6.9 mm, onlay oval 1.6 mm, P < 0.01). The onlay‐oval design was the largest implant with a median size of 35 mm, compared to 23 mm for the inset and 32 mm for the onlay round (P < 0.01). In addition, patellae using onlay‐oval implants required significantly fewer lateral facetectomies due to improved bone coverage (inset 95%; onlay round 87%; onlay oval 3%; P < 0.01). Finally, comparison of patient‐reported outcome measures between the groups showed no difference at an early assessment of 6 months.ConclusionOnlay‐oval design allows for the use of a larger implant, improving bone coverage and reducing the need for partial lateral facetectomy; however, early assessment of outcomes shows no difference between the three designs.

Many researchers emphasize the importance of studying sleep quality among patients with heart failure (HF). Because of the importance of this topic, many studies have been conducted to address the different aspects of sleep-in various populations of patients with HF. The purposes of our study were: to assess the types of disturbances in sleep within the different classes of HF, and to assess whether there were differences in the levels of sleep quality and types of disturbances in sleep within the different classes in non-hospitalized Jordan patients with HF. Data were gathered from 2 cardiac clinics and 2 medical clinics at 3 Jordan hospitals. A minimum sample of 200 people was recruited to participate in this study based on these criteria and factors. The prevalence of low sleep quality and types of disturbances in sleep were increased with the increase in New York Heart Association class. Nearly 3 quarters of the study sample had poor sleep quality 73.5% (n = 147). Using a score of 5 as a cut point, 147 patients with HF in our study sample had poor sleep quality. The most common types in all classes were waking up for urination, waking in the middle of the night or early morning, waking up due to coughing and snoring, and difficulty falling asleep within 30 minutes. However, waking up due to feeling cold or hot were rarely reported in all classes of patients with HF. Poor sleep quality negatively affects the quality of life in patients with HF by decreasing physical cognitive and psychosocial performance in those patients. This is the first study in literature study sleep quality in the different New York Heart Association functional classes.
