If you only need the buying answer: the current hardcover listing is the strongest clean route in this snapshot. It is far below the sampled new-hardcover comparator and far below the sampled lifetime eTextbook price. For a technique-heavy surgical reference, that makes ownership the clear value route.

What this book actually teaches
Knee Surgery: Tricks of the Trade is a procedural reference built around operative planning, surgical technique, decision points, and practical pearls in knee surgery. The book matters because it helps the reader think through how procedures are actually done, where pitfalls occur, and how technical choices affect outcomes. That is very different from a textbook meant only to summarize anatomy or pathology once.
That also means the book has real reuse value. Fellows, surgeons, sports-medicine specialists, and advanced trainees come back to technique-driven books when preparing cases, refining operative sequences, or checking details they do not want to leave to memory.
Why the hardcover is the stronger choice
Here the pricing and the educational use pattern point in the same direction. The current hardcover undercuts the sampled print comparator by a large margin and also comes in far below the sampled lifetime eTextbook price. When the keepable surgical reference is also the cheapest clean route, the ownership decision becomes unusually straightforward.
I would lean strongly toward the hardcover for orthopaedic trainees and practicing readers who expect to revisit knee procedures after the first pass through the book. I would only avoid ownership if institutional access already covers the material completely and a personal copy is unlikely to be used later.
