Tip 5: Punctuation can enhance your search as well. Use quotes ("search term") to only include pages with the same words in the same order. But only use this if you are looking for an exact word or phrase, otherwise you may exclude helpful results. Add an asterisk (search term*) as a placeholder for any unknown or wildcard terms. For example, C*l Tunnel would give you results for Cubital Tunnel and Carpal Tunnel. Place a question mark (search term?) for single-character wildcard matching. For example, pa?ent would give you results for parent, patent, etc. You may also use the plus sign (search + word) between words for words you must have in the results.
Unicompartmental knee replacement. Approximately 30 percent of people with knee osteoarthritis have disease that is largely restricted to one area of the joint. In these cases, unicompartmental knee replacement (also called partial knee replacement) may offer the same improvement and function as total knee replacement but with less trauma and better range of motion. A 2007 review that compared unicompartmental knee replacement with total knee replacement found a similar improvement in function, but fewer complications and less need for revision surgery after unicompartmental surgery.
