Summary: Anterior knee pain (AKP) is a common condition among young active patients and is associated with multiple causative factors. It can increase the risk of patellofemoral osteoarthritis and has a negative impact on the patient's quality of life and healthcare costs. Comprehensive evaluation and individualized treatment strategies are crucial for managing AKP.

Summary: The study indicates that performing patellar denervation during total knee arthroplasty does not significantly improve anterior knee pain and clinical outcomes compared to patellar replacement without denervation.

Summary: The relationship between chondromalacia patella (CMP) and the risk of developing herpes zoster (HZ) remains poorly understood. This study found that patients with CMP, especially elder adults and women, exhibited a higher risk of HZ. The assessment of HZ risk and the necessity of HZ vaccination should be informed for patients with CMP.

Summary: The objective of this study was to identify factors associated with kinesiophobia in individuals with patellofemoral pain (PFP) and interventions that may reduce kinesiophobia in individuals with PFP. The findings showed a moderate association between kinesiophobia and poorer function, as well as a weak association between kinesiophobia and higher pain in individuals with PFP. Taping and bracing immediately reduced kinesiophobia, while kinesiophobia-targeted interventions showed promise in reducing kinesiophobia following the full intervention.

Summary: This study aimed to evaluate the effects of preoperative patellar bone marrow lesions and patellar cartilage defects on postoperative anterior knee pain (AKP) after patellar non-resurfacing total knee arthroplasty (TKA). The results showed that the presence of preoperative bone marrow lesions with full-thickness cartilage defects in the patella was associated with worse postoperative AKP. Therefore, patellar resurfacing should be considered in this patient group to minimize the risk of developing residual AKP.

Summary: The study aimed to determine the intra- and inter-rater agreement of a derived Caton-Deschamps index (dCDI) for knee arthroplasty. It was found that the dCDI is a reliable radiological measure for patella height in knee arthroplasty, with high levels of intra- and inter-rater agreement similar to other commonly used indices.

Summary: This study aimed to investigate the importance of an isokinetic dynamometer in detecting muscle weakness and determining early treatment strategies in patients with chondromalacia patella (CMP). The findings showed that the isokinetic dynamometer can objectively evaluate muscle strength, and muscle weakness measured by isokinetic parameters is negatively correlated with symptom duration and MRI stages.

Summary: This study investigated the relationship between load tolerance of single leg isometric knee extension and athlete-reported knee pain location and severity during the single leg decline squat. The results showed that athletes with diffuse pain had lower load tolerance, while athletes with focal pain tolerated similar loads to those without pain. Furthermore, higher knee pain severity was associated with a consistent reduction in load tolerance.

Summary: Chondromalacia patella (CMP) is a condition characterized by abnormal softening of the cartilage of the underside the patella, causing anterior knee pain. This study aimed to compare the measured patellar cartilage cross-sectional area (PCCSA) between CMP patients and healthy controls. The results showed that CMP patients had significantly higher PCCSA compared to healthy controls, with a cutoff point of 116.24 mm(2) for predicting low grade CMP.

Summary: This study investigated the relationship between subcutaneous fat tissue thickness (SFTT) and chondromalacia patella (CP) using routine 1.5-Tesla magnetic resonance imaging (MRI) of the knee. The results indicate an association between SFTT and CP, with a positive correlation between SFTT and CP severity.

Summary: This study aimed to compare the clinical effectiveness of patella rim electro-cautery denervation versus no denervation in patients undergoing total knee arthroplasty (TKA). A randomized controlled trial was conducted on patients aged 40 years or older, who were scheduled for TKA without patella resurfacing. The results showed no clinically relevant benefit from patella rim electrocautery in these patients.

Summary: Total knee arthroplasty is a life-saving surgery for advanced gonarthrosis, but the controversy remains regarding patella resurfacing in TKA. This article presents a case of a 70-year-old Caucasian woman with stage IV Ahlback patellar arthrosis who underwent bilateral TKA with patellar resurfacing performed only on the right side. The article emphasizes the importance of developing high-quality studies to establish valid guidelines for patella resurfacing in TKA.

Summary: This study investigated the relationship between patellofemoral joint morphology and patellar chondromalacia, and found that abnormal patellofemoral joint morphology is associated with the occurrence and severity of chondromalacia.

Summary: In this study, the prevalence of anterior knee pain before and after total knee arthroplasty (TKA) was reported using a posterior-stabilized prosthesis with routine patellar resurfacing. It was found that preoperative anterior knee pain and worse self-reported function were associated with postoperative anterior knee pain.

Summary: The study found that females with PFP demonstrate altered trunk, pelvis, and knee joint kinematics during running compared to healthy controls. However, there were no significant differences in peak kinematic variables between the two groups. These findings suggest adaptive rigidity at the pelvis in PFP patients and potentially protective strategies to prevent further knee malalignment.
