Radiographic lucency of the glenoid component remains a problem after cement fixation in primary total shoulder arthroplasty. Glenoid component design likely contributes to rates of glenoid lucency. There were no significant differences in the rate of glenoid lucency between the 2 groups at immediate or an average 35-month follow-up. Both techniques appear to be viable options for initial glenoid component fixation, with cementless components allowing possible osseointegration, imparting potential long-term stability.

Prospective NFL athletes who have a previously diagnosed rotator cuff tear are significantly less likely to be drafted in the NFL draft and have a significantly shorter career, both in terms of total years played, games played, and games started than matched controls. The effect of a previous rotator cuff tear on career statistics is more pronounced in linemen than in athletes of other positions.
All-Arthroscopic versus Open Tenodesis of the Long Head of the Biceps Brachii

Biceps tenodesis remains a reliable treatment for pathologic abnormality of the long head of the biceps. Patients undergoing an all-arthroscopic suprapectoral tenodesis in the distal aspect or distal to the bicipital groove showed similar pain relief and clinical outcomes as compared with patients undergoing open subpectoral tenodesis. Open subpectoral biceps tenodesis may carry a higher complication risk secondary to a more invasive technique.

Mean global and focal acetabular anteversion was greater in women, and the prevalence of focal cephalad retroversion in the 1-o’clock position was not significantly different compared with men. Acetabular retroversion and anterior overcoverage are not more prevalent in women in the anterosuperior acetabulum, where femoroacetabular impingement most commonly occurs.

Persistent pain and dysfunction after a shoulder dislocation should prompt evaluation of the rotator cuff, especially in contact or overhead athletes, patients older than 40 years, or those with nerve injury. Surgery should be considered in the appropriately active patient with a rotator cuff tear after dislocation. While the current literature suggests improved stability and function after surgical repair of the rotator cuff, higher-quality prospective studies are necessary to make definitive conclusions.

Advances in the knowledge base and treatment techniques of intra-articular hip pain have allowed surgeons to address this complex clinical problem with promising outcomes. Improvements in hip arthroscopy have led to outcomes equivalent to open surgery while utilizing significantly less invasive techniques. However, outcomes may ultimately depend on the degree of underlying osteoarthritis.

In the existing literature, displaced proximal humerus fractures demonstrate improved Constant scores when treated with joint-preserving options. Age, fracture pattern, and complication rate are significant predictors of the Constant score independent of the selected treatment.

There is wide variation in patients’ estimates and understanding of health care costs. However, patients substantially overestimate reimbursement to the surgeon both in isolation and as a proportion of the total cost of the surgical procedure.

The study aim was to understand patient impressions of reimbursement to orthopedic spine surgeons. Our findings revealed that the majority of patients significantly overestimate the amount surgeons are reimbursed per procedure. Despite this, most feel that surgeons are appropriately compensated. Additionally, many patients are unaware of the global billing period.

In the first generations of modular tibial components, backside wear made a significant contribution to the particle burden released within the joint. This led to changes in design and materials to reduce micromotion and particle generation. In this retrieval study, we evaluate the efficacy of newer generations of knee implants in eliminating backside wear as a significant issue in TKR.
