A new randomized study from Australia suggests that for many patients, brief inpatient rehabilitation after knee replacement provides no benefits in several measures, compared with rehab at home.
However, “we are not concluding that there is no role for inpatient rehabilitation after knee arthroplasty,” said study coauthor Justine Naylor, PhD, of the University of New South Wales, Liverpool, Australia. “We are simply saying that for people who are otherwise well enough to be discharged directly home, inpatient rehabilitation does not provide more superior recovery across a range of outcomes.”
For the new study, conducted at two Australian hospitals during 2012-2015, researchers recruited patients aged 40 years or older with a primary diagnosis of osteoarthritis who were undergoing a primary unilateral knee arthroplasty and did not have complications such as a need for inpatient care in recovery beyond an initial 5 days after surgery.
The researchers randomly assigned 165 knee arthroplasty patients with uncomplicated cases to undergo either inpatient rehabilitation for 10 days and then recover at home for 6 weeks or a monitored 6-week home rehab program that began 2 weeks after surgery (JAMA. 2017;317[10]:1037-46).
A third group of 112 patients, 87 of whom were included in the primary analysis, were observed as they entered the home rehab protocol. They were in an initial group of 215 who declined to be randomized, mostly because they wanted to get home quickly after surgery.
The average age of all participants was 67 years, and just over two-thirds were women.
At 26 weeks, the researchers found that there was no significant difference in how the patients in the three groups fared on a 6-minute walk test (mean difference, −1.01 meters; 95% confidence interval, −25.56 to 23.55). They also found no significant difference in measurements of patient-reported pain and function (knee score mean difference, 2.06; 95% CI, −0.59 to 4.71), and quality of life (EQ-5D visual analog scale mean difference, 1.41; 95% CI, −6.42 to 3.60).
However, the patients did seem to have a preference. “Satisfaction with rehabilitation was significantly higher with inpatient rehab, average 92% vs. 83%, though both modes were well received overall,” Dr. Naylor said in an interview.
“Many patients who went to inpatient rehabilitation really enjoyed it,” she added. “We have observed that patients and carers like the convenience of inpatient rehab – a one-stop shop where patients get access to multiple clinicians, gyms, and other patients and do not have to prepare meals.”
However, she said, while “we have no doubt the inpatient rehabilitation environment is nurturing, there must also be advantages to being discharged directly home, otherwise we would have seen differences between the groups. It is possible that monitored home programs like the one provided in this study help people gain independence quickly and empower patients in their recovery.”
Dr. Naylor cautioned that inpatient rehabilitation does have potential benefits for certain patients, such as those who are the most impaired and those without someone available to care for them at home. “Future research could focus on what is best in those situations or, at least, design community-based programs [that] offer some of the perceived benefits of inpatient therapy,” she said. “In addition, we also need to know what the best rehabilitation approach is after hip arthroplasty.”
The study was funded by various sources, including a foundation grant. The study authors reported no relevant disclosures.
