GREGORY FRANK,

Plaintiff, OPINION AND ORDER v. 22-cv-476-wmc ANTHONY HENTZ SANDRA ENDER TAMMY MAASSEN LILY LIU, and DENISE HURLESS

Defendants.

Plaintiff Gregory Frank, representing himself, was granted leave to proceed with claims that defendants Anthony Hentz, Sandra Ender, Tammy Maassen, Dr. Lily Liu, and Denise Hurless acted with deliberate indifference to his serious medical needs following knee-replacement surgery in violation of the Eighth Amendment. (Dkt. # 31.) Before the court are defendants’ motions for summary judgment. (Dkt. ## 72, 76.) For the reasons explained below, the court will grant those motions.1 UNDISPUTED FACTS2 A. The parties At all times relevant, plaintiff Gregory Frank was in the custody of the Wisconsin

1 In addition, defendants Ender, Hentz, Hurless, and Maassen’s unopposed motion to amend their reply in support of their proposed findings of fact (dkt. #98) will be granted. 2 Unless otherwise indicated, the facts in this section are drawn from defendant Liu’s reply in support of their proposed findings of fact (dkt. # 95), defendants Ender, Hentz, Hurless, and Maassen’s amended reply in support of their proposed findings of fact (dkt. # 98), and plaintiff’s reply in support of his proposed findings of fact (dkt. # 97). Department of Corrections (“DOC”) and incarcerated at its Jackson Correctional Institution (“JCI”). Defendants Sandra Ender, Anthony Hentz, and Denise Hurless were all Nurse

Clinicians in JCI’s Health Services Unit (“HSU”). In this role, they treated and assessed inmates, assisted Advanced Care Practitioners (“ACP”), managed inmate medications, and maintained inmate medical records. As nurses, however, they did not have the authority to prescribe medications, determine a plan of care, or override medical decisions made by an ACP.

In turn, defendant Tammy Maassen was a Health Services Manager (“HSM”) at JCI. In her role as HSM, Maassen managed and supervised health care services, monitored established plans of care, and “provid[ed] liaison activities” to other institutional units and care providers. (Dkt. # 98-1, at 3.) Finally, defendant Dr. Lily Liu was a medical doctor employed at seven DOC correctional institutions. She worked two days a week at JCI.

B. Plaintiff Frank’s medical treatment On February 23, 2022, Frank underwent a total left knee arthroplasty at Gundersen

Health System (“Gundersen Clinic”).3 In preparation for surgery, Dr. Liu ordered and Advance Practice Nurse Practitioner (“APNP”) Wendy Demler wrote a medication order

3 “Total knee arthroplasty” also called “total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis. Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap. This surgery may be considered for someone who has severe arthritis or a severe knee injury.” Johns Hopkins Medicine, https://www.hopkinsmedicine.org/health/treatment-tests-and-therapies/knee-replacement-surgery- procedure (last visited July 16, 2026). for 5mg-325mg oral tablets of Hydrocodone-acetaminophen (“Norco”). (Dkt. # 26-1, at 1; dkt. #20-1, at 131, 138.) The administration of Norco was ordered to begin when Frank returned to JCI, with the medication to be taken four times a day for three days.

(Id.) Following his surgery, a prescription was also written and signed by a Gundersen Health System APNP, Molly Willenbring, which called for: 28 tablets of apixaban (Eliquis), which were to be taken “2 times daily for 14 days for deep vein thrombosis prevention in knee”; 30 tablets of oxycodone to be taken “by mouth every 6 hours as

needed for pain (severe pain);” and 30 tablets of tramadol to be taken “every 6 hours as needed for pain (moderate pain)” (“the Gundersen Prescription”). (Dkt. # 31-5, at 1.) Administration of these drugs was to begin on February 24, and each drug prescription was non-refillable. (Id.) In the Gundersen Clinic’s discharge instructions, APNP Willenbring stated “patient to return to DOC with preoperative medications unchanged and addition of Eliquis for dvt prophylaxis for 2 weeks and pain medications as needed for one month.”

(Dkt. # 78-1, at 11.) Consistent with Division of Adult Institutions (“DAI”) Policy #500.30.02(V)(B), which requires DOC ACPs to review offsite recommendations prior to implementation, dkt. #32-1, at 4, Dr. Liu ordered that upon Frank’s return JCI should continue “with pre-op medication and add [Eliquis] for DVT for two weeks and pain medications as needed for one month, JCI.” (Dkt. # 26-1, at 2.) On February 24, 2022, Frank returned to JCI and met with Nurse Ender and a

physical therapist. At that time, Ender noted that Frank was experiencing pain at a scale of eight out of ten; she was not sure “if his pain will be managed well”; and she gave Frank a prescribed oral tablet of Norco. (Dkt. # 20-1, at 31.) With physical therapy, Frank again reported his pain at an eight out of ten. The physical therapist indicated that the plan was to have one visit a week for six weeks, with the treatment to include: “manual

therapy, neuromuscular reeducation, orthotic training, therapeutic activities, therapeutic exercises, and thermal/light modalities.” (Dkt. #20-1, at 25.) On February 25, Frank was seen by Ender for a dressing change. During the dressing change, Ender cleaned Frank’s knee and placed a dry dressing that was rewrapped with an ace bandage. At that time, Ender observed “quite a bit of bruising” on Frank’s knee. (Dkt.

#20-1, at 2-3.) Ender also noted that Frank “has some pain but wants to come to HSU only a couple times a day.” (Id.) That same day, Frank received two tablets of Norco, even though he was permitted to take it up to four times a day. The following day, February 26, Frank was again seen for a dressing change by a non-defendant nurse, who replaced the previous wrap and dressing with new dressings and again wrapped the knee in an ace bandage for compression. That nurse also noted that

Frank’s knee “remains extremely bruised and swollen, however, the edema is much reduced.” (Id.) Once again, Frank only took two tablets of Norco. The next day, February 27, Frank was seen by Nurse Hurless for yet another dressing change. Hurless observed “very minimal drainage” compared to Frank’s previous dressing, but noted that swelling and bruising on Frank’s knee was still present. (Id.) During this dressing change, Frank reported that the “pain is much better” and he was

“able to walk using a walker.” (Id.) Hurless also instructed Frank to contact HSU with any concerns. Frank took two tablets of Norco that day, then only one tablet the following day, February 28. On March 1, Frank underwent an additional dressing change, with HSU staff noting that the surgical site was “clean dry and intact.” (Id.) While Frank’s knee was still

displaying moderate bruising in different shades, there were no signs or symptoms of infection noted. Frank also “report[ed] not having taken anything for pain control and that he has been ambulating more.” (Id.) HSU staff informed Frank to elevate his knee and changed this compression wrapping to “Tubigrip.” Also on March 1, Frank filed a Health Service Request (“HSR”), stating that his bandage had not been replaced or his

wound checked in two days. Nurse Hentz responded on March 2, reminding Frank that he had been seen by nursing staff on March 1 and advising that he would be seen again by nursing staff that same day. Frank apparently saw Nurse Ender on March 2, for a dressing change. However, he did not apply any new dressing because there was no sign of drainage. Instead, Ender observed bruising “up to the hip area and around the entire upper thigh” and “down the front of his leg too.” (Id. at 1.)
