Total knee arthroplasty (TKA) is an excellent surgery to improve pain and function in patients with osteoarthritis.

Satisfaction after TKA occurs in over 80% of patients. Trends in orthopaedic clinical
practice have predicted the number of TKAs to soon surpass 1,000,000 procedures
performed annually in the United States.

Given this increase, the number of complications after TKA is also expected to
increase. Arthrofibrosis is a common complication after TKA and is characterized
by the formation of excessive scar tissue, resulting in pathologic stiffening of the joint and decreased range of motion (ROM).

It represents significant patient and economic burdens, accounting for 28% of hospital readmissions within 90 days of arthroplasty and 10% of revision TKAs (rTKAs) within 5 years. Understanding current concepts of arthrofibrosis to risk-stratify patients and optimize patient outcomes is imperative. This critical analysis review covers the definition, epidemiology, diagnosis, pathogenesis, and management of arthrofibrosis after TKA.

What’s New in Musculoskeletal Tumor Surgery

The literature on musculoskeletal tumors continues to be robust; however, it has been dominated by retrospective obser- vational studies. For bone sarcomas, cytotoxic chemotherapy remains the mainstay of systemic therapy, with no new, effective, targeted biologic interventions. There has been a renewed focus on functional outcomes and socioeconomic factors associated with oncologic outcomes and ongoing interest in pelvic reconstruction, which continues to have high rates of surgical complications.
