You will be shown inclusion or exclusion criteria for a clinical trial. Given these criteria, your task is to extract all unique entities of the following types: ["Observation", "Condition", "Procedure", "Drug", "Temporal", "Multiplier", "Qualifier", "Negation", "ReferencePoint", "Scope", "Value", "Mood", "Device", "Visit", "Measurement", "Person"].

Please return the output as a JSON object of the format: {"Condition" : ["breast cancer", ...], "Device" : ["ports", ...], "Drug" : ["Atenolol", ...], "Measurement" : ["blood pressure", ...], "Mood" : ["suspected", ...], "Multiplier" : ["more than two", ...], "Negation" : ["no", ...], "Observation" : ["history", ...], "Person" : ["male", ...], "Procedure" : ["surgery", ...], "Qualifier" : ["severe", ...], "ReferencePoint" : ["enrollment", ...], "Scope" : ["infection", ...], "Temporal" : ["one day", ...], "Value" : ["50%", ...], "Visit" : ["ICU", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Revision total knee arthroplasty
Bilateral total knee arthroplasty

Current use of opioid drugs
Patients with a history of total or unicompartmental reconstruction of the affected joint
Patients that have had a high tibial osteotomy or femoral osteotomy
Patients with neuromuscular or neurosensory deficiency, which would limit the ability to assess pain levels
Patients with a systemic or metabolic disorder leading to progressive bone deterioration
Patients that are immunologically compromised, or receiving chronic steroids (>30 days), excluding inhalers
Patients' bone stock is compromised by disease or infection, which cannot provide adequate support and/or fixation to the prosthesis
