Statin Use Not Linked to Rotator Cuff Retear After Arthroscopic Rotator Cuff Repair
1Department of Orthopaedic Surgery, Fukui General Hospital, Fukui, Japan.
Insights
This study found no link between cholesterol levels and rotator cuff repair healing. Statin use also did not significantly impact retear rates, though age, male sex, and tear size were key risk factors.
Area of Science:
- Orthopedic Surgery
- Biomedical Research
- Musculoskeletal Health
Background:
- Rotator cuff tears are common, and successful healing after arthroscopic repair is crucial for patient recovery.
- Hyperlipidemia and statin use are potential factors influencing healing, but their impact on rotator cuff repair integrity remains unclear.
Purpose of the Study:
- To investigate the association between serum lipid levels (total cholesterol, LDL, triglycerides) and statin use with retear rates after arthroscopic rotator cuff repair.
- To identify significant risk factors for rotator cuff retear.
Main Methods:
- Retrospective review of 620 patients undergoing arthroscopic rotator cuff repair.
- Analysis of serum lipid levels, statin use (type 1 and type 2), and rotator cuff retear status (assessed by MRI using Sugaya classification).
- Multivariate logistic regression was used to identify risk factors for retear.
Main Results:
- No statistically significant association was found between serum lipid levels and rotator cuff retear.
- Statin use (type 1 or type 2) did not significantly affect retear rates.
- Older age, male sex, and large-to-massive tear size were identified as significant risk factors for retear.
Conclusions:
- Serum lipid levels and statin use are not significantly associated with rotator cuff retear after arthroscopic repair.
- Age, male sex, and large tear size are significant predictors of retear.
- Further research may explore nuanced effects of different statin types.
Purpose:
To evaluate the risk factors, including hyperlipidemia and statin use, on rotator cuff healing after arthroscopic repair.
Methods:
A retrospective review of prospectively collected cases who underwent arthroscopic rotator cuff repair was conducted. Total cholesterol, low-density lipoprotein, triglycerides levels, and the presence or absence of statin use and type of statins used (type 1 naturally derived statins and type 2 synthetic statins) were reviewed. Repair integrity was determined according to the Sugaya classification, assessed by magnetic resonance imaging (types 4 and 5 were considered retear). Including serum lipid levels and statin use, potential risk factors for retear were tested using multivariate logistic regression.
Results:
Six hundred twenty cases were evaluated. The mean age was 66.9 years; 348 were male, and 272 were female. The overall retear rate was 16.1%. There was no statistically significant difference in serum lipid levels among the categories of the Sugaya classification. Multivariate logistic regression analysis showed no association between serum lipid levels and odds ratio for retear: total cholesterol (odds ratio [OR] 1.00; P = .72), low-density lipoprotein (OR 0.99; P = .44), and triglycerides (OR 1.00; P = .88). Statins did not have a statistically significant increase or decrease in odds: type 1 statin (OR 0.3; P = .061) and type 2 statin (OR 1.4; P = .26). Older age (OR 1.1; P < .0001), male sex (OR 1.8; P = .021), and large-to-massive cuff tear size (OR 3.4; P < .0001) were significant risk factors.
Conclusions:
No association was found between serum lipid levels and retear after arthroscopic rotator cuff repair. Statin use was not a statistically significant factor for retears, but different trends were seen for type 1 and type 2 statins. Older age, male sex, and large to massive tears were significant risks for retears.
Level Of Evidence:
Level III, retrospective cohort design, prognosis study.

Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
