🚩 Free to read all month: "One of the most prevalent and harmful epidemics both in contemporary medicine and orthopaedic surgery is not caused by an infectious disease, but rather by physicians like us. We speak, of course, of overdiagnosis and overtreatment," write Drs. Eugene Rezk & David Ring in this month's editorial.

"Fortunately, incorporating practical concepts from Bayesian reasoning into our decision-making framework may help us overcome the common errors that contribute to these problems," they write. "The Bayesian framework is not a parlor trick for statisticians; it is simply the formalized version of the same iterative, context-sensitive reasoning surgeons have always employed."

"I enjoyed reading the column by Dr. Joseph Bernstein that explored the so-called 'sports injury epidemic.' While it does seem plausible that modern athletes are responding rationally to powerful incentives, I believe the economic neatness of that explanation hides deeper asymmetries," writes medical student Bishoy Kirollos in his award-winning letter to .

This thoughtful letter won 1st place in CORR's Letter to the Editor Contest for medical students, residents, and fellows last year—and we're hosting the contest again this year! To enter, medical trainees from anywhere in the world (and from any specialty) must submit a Letter to the Editor about an item published in CORR by the end of 2026.

In , Qin et al. demonstrate how the C2-6 Cobb angle can serve as a reliable alternative to the C2-7 Cobb angle for the evaluation of cervical sagittal alignment and share a free, online prediction tool to help translate these findings into practice.

"In daily practice, when C7 is obscured by shoulder shadows, surgeons and radiologists may add approximately 6° to the measured C2-6 Cobb angle to approximate the C2-7 Cobb value," the authors write.

"The next few studies on this topic should focus on short- and midterm clinical and radiographic results after cervical deformity reconstruction using the tool provided by Qin et al.," writes Panagiotis Korovessis MD, PhD in a commentary.

"Effective since the beginning of 2026, Medicare TEAM is the first mandatory, episode-based payment model for certain orthopaedic procedures at over 700 hospitals," write Zhuang et al. in the latest Value-based Healthcare column. "Achieving quality and cost targets will require surgeons to take ownership of the care continuum, distributing resources at each stage according to patient complexity, otherwise known as complexity matching."

In patients treated with TKA for medial osteoarthritis (OA), Song et al. found that posterior tibial slope progressively increased as the chondral wear pattern shifted from anterior to posterior, with the highest values observed in knees demonstrating posteromedial OA.

"These findings underscore the importance of evaluating posterior tibial slope when planning treatment for medial OA, as unintended changes may be associated with chondral wear patterns and clinical outcomes," the authors write.

"The impact of excessive posterior slope on the natural history of degenerative arthritis of the knee needs to be better described," writes Charles Cornell MD in a commentary. "Specifically, can accurate measurement of posterior tibial slope help predict the progression to a pattern of degenerative arthritis characterized by posterior wear and ACL insufficiency?"

In the third consensus study in this month's proceedings, Leopold et al. provide an algorithmic approach for how imaging should be used for suspected hip instability: Start with standardized radiographs and add MRI or CT in a stepwise, question-driven manner if soft tissue stabilizers or 3D bony morphology require clarification.

"Characteristic morphologic parameters should anchor decision-making, whereas emerging soft tissue and dynamic markers should be applied cautiously until standardized and validated," the authors write.
