Pursuant to Section 287.140.1, an employer is required to provide care "as may be reasonably required to cure and relieve from the effects of the injury." This includes allowance for the cost of future medical treatment. *Pennewell v. Hannibal Regional Hospital*, 390 S.W.3d 919, 926 (Mo. App. E.D. 2013) citing *Poole v. City of St. Louis*, 328 S.W.3d 277, 290-91 (Mo. App. E.D. 2010). An award of future medical treatment is appropriate if an employee shows a reasonable probability that he or she is in need of additional medical treatment for the work-related injury. *Id.* Future care to relieve [an employee's] pain should not be denied simply because he may have achieved [maximum medical improvement]. *Id.* Therefore, a finding that an employee has reached maximum medical improvement is not necessarily inconsistent with the employee's need for future medical treatment. *Id.*
To receive an award of future medical benefits, a claimant need not show "conclusive evidence" of a need for future medical treatment. *ABB Power T & D Co. v. Kempker*, 236 S.W.3d 43, 52 (Mo.App. W.D. 2007). Instead, a claimant need only show a "reasonable probability" that, because of a work-related injury, future medical treatment will be necessary. *Id.* A claimant need not show evidence of the specific nature of the treatment required. *Aldridge v. Southern Missouri Gas Co.*, 131 S.W.3d 876, 883 (Mo.App. S.D. 2004); *Stevens v. Citizens Memorial Healthcare Foundation*, 244 S.W.3d 234, 237 (Mo.App. S.D. 2008).
In determining whether medical treatment is "reasonably required" to cure or relieve a compensable injury, it is immaterial that the treatment may have been required because of the complication of pre-existing conditions, or that the treatment will benefit both the compensable injury and a pre-existing condition. *Tillotson v. St. Joseph Med. Ctr.*, 347 S.W.3d 511, 519 (Mo.App. W.D 2011). Rather, once it is determined that there has been a compensable accident, a claimant need only prove that the need for treatment and medication flow from the work injury. *Id.* The fact that the medication or treatment may also benefit a non-compensable or earlier injury or condition is irrelevant. *Id.* Application of the prevailing factor test to determine whether medical treatment is required to treat a compensable injury is reversible error. *Id.* at 521.
In this case, all of the medical evidence establishes, based upon a reasonable degree of medical certainty, the claimant is a candidate for right knee replacement. Three physicians presented varying findings relating to the etiology of this requirement. Dr. Volarich testified, based upon a reasonable degree of medical probability, the claimant requires knee replacement and the need for knee replacement is a result of the work-related injuries of April 23, 2014, and January 27, 2015. See Dr. Volarich deposition, pages 29-33. He opined,
> The need for the right knee joint replacement flows directly from these work-related injuries of 4/23/14 and 1/27/15, since he was asymptomatic in that right knee prior to 4/23/14. The work injuries of 4/23/14 and 1/27/15 are the prevailing factors necessitating the need for joint replacement in the future. The decision to perform any additional surgery should be made in conjunction with his wishes, of symptoms, and expert surgical opinion. These treatments are necessary to cure and relieve from the ill effects of his work-related injuries. See Dr. Volarich deposition, pages 31-32.

Dr. Thomas, an orthopedic surgeon, examined the claimant on January 17, 2017, and opined, "I think his current pain is such that he needs treatment at this time. I would first recommend cortisone, physical therapy, anti-inflammatory medications, and glucosamine/chondroitin. If he does not see relief quickly, I would recommend Visco supplementation with hyaluronic acid injections. Despite his young age, I think arthroplasty is the only option that will give him persistent pain relief. I get the impression he will elect for that in the near future. Unfortunately, we still quote 10-15 year survivorship for total knee arthroplasty. Therefore, the odds are that he will require 1-2 revisions in his lifetime. Each one carries more significant perioperative risks and likely a lesser survivorship." See Exhibit 10.
Dr. Thomas testified the claimant needs a knee replacement. See Dr. Thomas deposition dated May 3, 2017, pages 11-15. He currently has bone-on-bone arthritis in the right knee, which will ultimately require a knee replacement. See Dr. Thomas deposition dated May 3, 2017, page 12. He testified that the work-related injuries and the treatment that the claimant received as a result of those work-related injuries are the primary causes of the bone-on-bone arthritic condition and the need for the knee replacement. See Dr. Thomas deposition dated May 3, 2017, page 15.
On March 9, 2018, Dr. Thomas reported about the change in mechanics of the operation of the knee as a result of partial removal of the medial meniscus. See Exhibit 12. He opined, "It is my opinion that the injury lead to the tear in the meniscus which led to surgery. In the claimant, this changed the mechanics of the knee that lead to rapid acceleration of the degenerative process that he likely has in the contralateral side. He now has advanced degenerative changes that he would not have had at this point in his life without the injury. Simply put, the injury lead to the surgery which lead to his current condition of having advanced degenerative changes." See Exhibit 12.
On May 22, 2018, Dr. Thomas testified about the manner in which the injury and surgeries caused the current need for a knee replacement. He noted the degenerative conditions in the right and left knees were virtually identical at the time of the first injury. See Dr. Thomas deposition dated May 22, 2018, page 8. The only difference between the right knee and the left knee was the injury and the subsequent tri-compartmental procedures in the right knee. The majority of the medial meniscus had been removed in the two surgeries. See Dr. Thomas deposition dated May 22, 2018, page 9. The impact of this changed the mechanics in the right knee, increased the loading, and had an impact on the entire knee because it affected stability and redistributed the forces, changing stresses throughout the entire knee joint. He opined that the two separate injuries and surgeries changed the mechanics in the knee resulting in an inflammatory response, which caused severe destruction of the knee joint. See Dr. Thomas deposition dated May 22, 2018, page 10. He opined, "My opinion is that the injury led to the tear in the meniscus, which led to the surgery, which led to the disruption to the mechanics of the knee joint that led to the degenerative changes necessitating knee replacement." See Dr. Thomas deposition dated May 22, 2018, page 17. He opined that these were the prevailing factors in the need for knee replacement. See Dr. Thomas deposition dated May 22, 2018, pages 17, 24.

Dr. King also opined the claimant will require a knee replacement when he can no longer tolerate the pain in his right knee. However, he also opined, "his degeneration was significant at the time of his first injury and the expected progression was progression of his degeneration and his symptoms over time, which is the natural history of that condition." See Dr. King deposition, page 24. "In this case, genetics is the biggest factor." See Dr. King deposition, page 24. Thus, he concluded the need for a knee replacement is a result of pre-existing degenerative changes and the injuries and subsequent treatment did not change the mechanics of the knee or cause the need for a knee replacement. See Dr. King deposition, pages 24-31.
Dr. King also testified the claimant had no history of complaints or symptoms in the right knee prior to April 23, 2014. See Dr. King deposition, page 32. People have degenerative changes in their knees without there being symptoms or clinical problems. See Dr. King deposition, page 33. The pre-existing degenerative disease did not mean that the claimant would require either arthroscopies or surgical procedures in this case. See Dr. King deposition, page 34. The April 28, 2014, X-rays showed the medial and lateral joint space compartments were well maintained which is an indication there had not been substantial damage to cartilage in those compartments at the time of the initial injury in this case. See Dr. King deposition, page 34. Dr. King testified he performed procedures in the patellofemoral compartment and the medial compartment in his first surgery and it was not a very successful surgery. See Dr. King deposition, page 37. He testified there was an oblique tear in the medial meniscus, which he did not surgically remove at the time of his first surgery. See Dr. King deposition, pages 38-39. He testified when you remove a part of the meniscus the tissue is no longer there to work as a shock absorber or to cushion. This increases the load on the medial compartment. See Dr. King deposition, page 41. He testified X-rays performed at the University of Missouri on November 4, 2014, showed moderate tri-compartmental osteoarthritis in both knees. See Dr. King deposition, page 43. He testified degenerative conditions in both knees did not require surgery but they imposed an increased risk for surgery. See Dr. King deposition, page 44. He testified injuries do or can be responsible for accelerating degeneration of pre-existing conditions. See Dr. King deposition, page 45. When asked about whether surgery can accelerate the degenerative process, he testified:
Q. Well, that's what I am saying, doctor, is that that meniscus still has a function right?
A. Correct.
Q. And when you begin removing parts of it and when it's been damaged, that is one of the things that can accelerate the continued degeneration of that meniscus, isn't it?
A. If you remove more than -- if you tear and subsequently have to remove more than fifty percent, then yes.
Q. Okay. You did a second surgery on Mr. Hooper on March the 20th of 2015, is that correct?
A. That's correct.
Q. By the end of that surgery the majority of the meniscus had been removed, hadn't it?
A. That's correct. See Dr. King deposition, page 46.

Dr. King testified by the end of the second surgery the biomechanics of the knee had changed. See Dr. King deposition, page 47. By the end of the second arthroscopic surgery, Dr. King examined all three compartments of the knee and had performed surgical procedures in all three compartments. See Dr. King deposition, pages 48-50.
Dr. King testified the claimant had moderate tri-compartmental degeneration in both knees at the beginning. See Dr. King deposition, page 59. While the right knee had been twice injured resulting in two surgeries involving all three compartments, the left knee remained non-symptomatic. See Dr. King deposition, page 59. Dr. King testified he was unaware of any difference between the right knee, which requires replacement, and the left knee that did not, except the two injuries and the arthroscopic procedures on the right knee, because he did not have enough information about the condition of the claimant's left knee. See Dr. King deposition, pages 59-61.
Based on the weight of the evidence, the need for future medical care to the claimant's right knee flows from the claimant's work-related injuries and he is awarded medical care as may be reasonably required to cure and relieve from the effects of the injury.
PERMANENT DISABILITY
Permanent partial disability or permanent total disability shall be demonstrated and certified by a physician. Medical opinions addressing compensability and disability shall be stated within a reasonable degree of medical certainty. In determining compensability and disability, where inconsistent or conflicting medical opinions exist, objective medical findings shall prevail over subjective medical findings. Objective medical findings are those findings demonstrable on physical examination or by appropriate tests or diagnostic procedures. Section 287.190.6(2), RSMo 2016.
Workers' Compensation awards for permanent partial disability are authorized pursuant to Section 287.190. "The reason for [an] award of permanent partial disability benefits is to compensate an injured party for lost earnings." *Rana v. Landstar TLC*, 46 S.W.3d 614, 626 (Mo. App. W.D. 2001). The amount of compensation to be awarded for a PPD is determined pursuant to the "SCHEDULE OF LOSSES" found in Section 287.190.1. "Permanent partial disability" is defined in Section 287.190.6 as being permanent in nature and partial in degree. Further, "[a]n actual loss of earnings is not an essential element of a claim for permanent partial disability." *Id.* A permanent partial disability can be awarded notwithstanding the fact the claimant returns to work, if the claimant's injury impairs his efficiency in the ordinary pursuits of life. *Id.* "[T]he Labor and Industrial Relations Commission has discretion as to the amount of the award and how it is to be calculated." *Id.* "It is the duty of the Commission to weigh that evidence as well as all the other testimony and reach its own conclusion as to the percentage of the disability suffered." *Id.* In a workers' compensation case in which an employee is seeking benefits for PPD, the employee has the burden of not only proving a work-related injury, but that the injury resulted in the disability claimed. *Id.*

In this case, Dr. Volarich evaluated the claimant's condition to determine whether the claimant suffered any permanent disability to his right knee due to the work-related injury. The claimant and his wife testified the claimant suffers from significant limitations to his activities due to the reduction in claimant's right knee. They testified the claimant suffers from severe swelling and chronic pain aggravated by activities and he spends most evenings sitting in a recliner, icing his knee, using a TENS unit, and taking over-the-counter medications. He testified he has limitations at work that also interfere with recreational and family activities.
On November 3, 2015, Dr. Volarich examined the claimant and reviewed his medical records. Referable to the January 27, 2015 injury, Dr. Volarich opined the claimant suffered an additional 30% permanent partial disability of the right knee due to the recurrent meniscal tear and irreversible aggravation of chondromalacia, which required arthroscopic partial medial meniscectomy, removal of loose body, chondroplasty of the patella, trochlear groove, medial femoral condyle and medial tibial plateau. The rating accounts for the injury's contribution to pain, loss of motion, crepitus, and swelling in the right lower extremity. See Dr. Volarich deposition, page 28.
Based on the weight of the evidence, the claimant suffered a 20% permanent partial disability to his right knee due to the 2015 work-related injury.
I certify that on 4-5-19
I delivered a copy of the foregoing award to the parties to the case. A complete record of the method of delivery and date of service upon each party is retained with the executed award in the Division's case file.
