Typical Clinical Scenarios

A 72-year-old patient with end-stage osteoarthritis of the left knee presents for a scheduled inpatient elective joint replacement after failing conservative measures (physical therapy, injections, and analgesics). The surgical plan is to remove the diseased articular surfaces and implant prosthetic components to restore joint function and relieve chronic pain; an open approach is used targeting the left knee joint lateral meniscus region when that component is the primary focus of replacement. Typical codes: XRRH0L8
A 65-year-old active patient with progressive medial compartment osteoarthritis and mechanical symptoms (catching, locking) is admitted electively for a partial knee replacement focused on the medial meniscus area to preserve uninvolved structures and speed recovery; the operation is performed via an open approach to place a synthetic substitute for the affected compartment. Typical codes: XRRH0M8
A 68-year-old patient with prior left knee surgery develops severe pain and instability from failed previous procedures with loss of joint function; inpatient revision replacement is undertaken via an open approach to remove failed components and implant a synthetic substitute for the affected meniscal compartment as part of reconstructing the left knee joint. Typical codes: XRRH0L8, XRRH0M8
