Intravenous plus periarticular corticosteroids improve rehabilitation measures after knee replacement

However, combination doesn't improve pain relief, reports Journal of Bone and Joint Surgery

2023-05-25
(Press-News.org) May 25, 2023 – For patients undergoing total knee arthroplasty (TKA), a combination of intravenous and periarticular corticosteroids does not improve pain control – but, may improve key indicators of functional recovery in the days after surgery, reports a trial in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio in partnership with Wolters Kluwer.

Intravenous (IV) plus periarticular (PA) steroids "yielded more significant improvements in the rehabilitation parameters," such as knee movement and walking distance, according to the report by TCW Chan, MBBS, of Queen Mary Hospital, Hong Kong, and colleagues. "Thus, there was more robust evidence that corticosteroids enhanced functional recovery in the patients who received both PA and IV corticosteroids than in those who received intravenous corticosteroids only."

Trial compares two routes of corticosteroid administration for TKA

TKA is a widely performed and cost-effective procedure, but many patients experience substantial postoperative pain. Previous studies have reported effective pain relief and improved mobilization after TKA with either IV or PA corticosteroid administration.

Chan and colleagues aimed to assess whether a combination of IV and PA corticosteroids could provide further improvement. In the new study, 178 patients undergoing initial TKA were randomly assigned to receive IV, PA, or IV plus PA corticosteroids. A fourth group received inactive placebo injections. All patients received standard opioid medications for pain.

Pain relief and key rehabilitation parameters were compared across groups. Patients and the researchers evaluating outcomes were both blinded to the treatment the patients received.

In first few postoperative days, pain scores at rest and during movement were significantly lower for patients who received IV corticosteroids, with or without PA corticosteroids, as compared with the placebo group. Patients who received PA corticosteroids alone had no reduction in pain scores compared with the placebo.

IV plus PA corticosteroids may enhance functional recovery

The combined use of IV plus PA corticosteroids led to improvement in several physical measures during rehabilitation. At three days, flexion in the operated knee was better for patients who received IV plus PA corticosteroids compared with the placebo.

The IV plus PA corticosteroid group also had greater quadriceps muscle strength and longer walking distances during the first three postoperative days, as well as higher scores on an elderly mobility scale. Some parameters, but not all, were also improved for patients who received IV or PA corticosteroids alone, as compared with the placebo.

Patients who received IV plus PA corticosteroids were also more likely to be discharged home from the hospital, rather than to a rehabilitation facility (67% compared with 38% in the placebo group). Rates of discharge to home were 55% with IV corticosteroids alone and 59% with PA corticosteroids alone.

The study confirms the role of IV corticosteroids in pain management after TKA, with significant reductions in pain scores and morphine use compared with a placebo. Adding PA to IV corticosteroids does not improve postoperative pain control.

However, the combined use of IV plus PA corticosteroids provided greater functional recovery immediately postoperatively. The researchers write, "These improvements in rehabilitation and recovery parameters may have contributed to the higher percentage of patients who were discharged home."

Dr. Chan and colleagues conclude: "This study provides new insights into pain management in TKA that may enable better functional recovery and rehabilitation after TKA, and thereby advance the ability to perform arthroplasty as an outpatient procedure."

Scientists target human stomach cells for diabetes therapy

Scientists target human stomach cells for diabetes therapy
2023-05-25
Stem cells from the human stomach can be converted into cells that secrete insulin in response to rising blood sugar levels, offering a promising approach to treating diabetes, according to a preclinical study from researchers at Weill Cornell Medicine. In the study, which appeared April 27 in Nature Cell Biology, the researchers showed that they could take stem cells obtained from human stomach tissue and reprogram them directly—with strikingly high efficiency—into cells that closely resemble pancreatic insulin-secreting cells known as beta cells. Transplants of small groups of these cells reversed disease signs in a mouse model of diabetes. “This ...

Epigenetic mechanisms activated by GHK-Cu increase skin collagen density in clinical trial

Epigenetic mechanisms activated by GHK-Cu increase skin collagen density in clinical trial
2023-05-25
Skin loses collagen and elastin and becomes progressively thinner with age leading to wrinkles, so reversing this age-related loss of skin density is the holy grail of anti-aging treatments. One compound capable of doing that is the naturally occurring peptide GHK-Cu (GHK from glycyl-L-histidyl-L-lysine bound to a copper ion), which affects 31.2% of the human genes by either activating or deactivating them (based on a criterion of a reduction or increment in gene activity of more than 50%), meaning that it works by ...

A metabolic process in cancer cells could unlock a possible treatment for glioblastoma

2023-05-25
A study led by researchers at the UCLA Jonsson Comprehensive Cancer Center has found that targeting a metabolic process in people with a specific genetic mutation could help treat glioblastoma, an aggressive brain cancer. The genetic alteration — a deletion in a gene called CDKN2A — is present in about 60% of people who have glioblastoma. The mutation causes changes in the way lipids are distributed in cancer cells, which in turn makes the cancer cells vulnerable to being destroyed. The ...

Can sugar and fat influence immune cell responses?

Can sugar and fat influence immune cell responses?
2023-05-25
LA JOLLA, CA—A population of unconventional white blood cells has recently captured the attention of immunologists and clinicians alike. Unlike conventional T cells, which circulate throughout the body in our blood, mucosal-associated invariant T (MAIT) cells are largely found in tissues where they provide immune protection against a broad range of diseases.  MAIT cells are highly abundant in humans. Although they make up only 2 percent of the lymphocytes in blood, MAIT cells account for 10 to 40 percent of lymphocytes in the liver, and they are common in tissues such as lungs. Still, much about MAIT cell biology and clinical function remains unknown. In ...

County-level maternal vulnerability and preterm birth

2023-05-25
About The Study: The findings of this study using data for 3.6 million births suggest that the Maternal Vulnerability Index (MVI), a novel county-level index designed to quantify maternal vulnerability to adverse health outcomes, was associated with preterm birth even after adjustment for individual-level confounders. The MVI is a useful measure for county-level preterm birth risk that may have policy implications for counties working to lower preterm rates and improve perinatal outcomes.  Authors: Sara C. Handley, M.D., M.S.C.E., Children’s Hospital of Philadelphia, is the corresponding author.  To ...
