Degenerative conditions of the knee place an increasing burden on health economies and lead to pain and functional loss for sufferers. Although arthroplasty may not offer a level of functional restoration that meets all patients' expectations, joint preservation through osteotomy is a viable option in younger, more physically active patients. This volume is a comprehensive technical guide to performing knee-preserving surgery to treat degenerative conditions and malalignment-associated knee instability. Drawing on their extensive experience of these procedures, the authors provide valuable insights into identifying patients who may benefit, as well as planning and performing the procedures with a high degree of precision, and explaining the results that can be achieved.
