Paragraph Number

2

Arthroplasty procedures can be used to relieve pain in or restore function of a joint due to conditions such as osteoarthritis, rheumatoid arthritis, or other joint conditions through minimally invasive or invasive surgery. An arthroplasty procedure can be performed on any joint and may include a partial or total joint replacement with a replacement prosthesis or prostheses. During an arthroplasty procedure, a surgeon may want to measure a size of an opening between two bones of the joint. In addition, the surgeon may also want to measure a balance of the joint in addition to a size of an opening (referred to as a gap) between two bones of the joint. For example, during partial or total knee replacement (TKR) arthroplasty, a surgeon may desire to gauge or measure a displacement between two bones of the joint and a balance of the joint. Taking such measurements during minimally invasive or invasive arthroplasty can be a challenge given forces applied to the joint by ligaments and other soft tissue of or around the joint. Accordingly, a need exists for improved systems and methods to measure the gap and/or angulation between bones in the course of an arthroplasty procedure.
