Low-dose, short-duration NSAID exposure did not significantly affect bone union rates, with an odds ratio of 1.68 that was not statistically significant. In pediatric patients, NSAIDs did not have a significant effect on bone healing. These findings demonstrate that while brief, low-dose NSAID use may be safe for bone healing, extended or high-dose use significantly impairs the body's ability to heal bone.

The authors explain that while the term tendinitis implies inflammation, chronic tendon conditions actually involve a disordered and degenerative healing process rather than active inflammation. Despite this distinction, the review finds that NSAIDs and corticosteroids still have a role in treatment. Short-term use of NSAIDs reduces pain and increases range of motion, which can help patients participate in rehabilitative exercises that are essential for recovery. The mainstays of treatment are identified as activity modification, relative rest, pain control, and protection of the injured tissue. The authors note that cryotherapy has a role in controlling pain despite limited high-quality evidence. Importantly, they caution that care should be taken with corticosteroid injections into and near major load-bearing tendons because of the risk of rupture. The review supports a treatment approach where NSAIDs are used strategically as part of a broader protocol rather than as a standalone solution. By reducing pain and inflammation in the short term, NSAIDs can facilitate rehabilitation and activity modification, but they should not be relied upon indefinitely.

After 2 weeks of exposure, the tendon cells had lost their normal fibroblastic appearance and parallel orientation, showing characteristics of cellular degeneration similar to what is seen in damaged tendons in the body. The production and secretion of collagen type I, which is the primary structural protein in healthy tendons, was strongly reduced. Cell proliferation decreased and cell migration was completely blocked, meaning the tendon cells lost their ability to move and repair damaged tissue. The expression of matrix metalloproteinases, enzymes needed for tissue remodeling, was reduced, while their inhibitors were increased, further impairing the repair process.

The review found that at low doses of 800 to 1,200 mg per day, which are the doses approved for over-the-counter use in many countries, ibuprofen has a safety profile comparable to paracetamol (acetaminophen). Its pain-relieving activity is directly linked to its anti-inflammatory effects, specifically through the reduction of cyclooxygenase (COX-1 and COX-2) enzymes that produce inflammatory prostaglandins. Unlike paracetamol, ibuprofen does not carry a risk of liver damage, and unlike aspirin, it does not cause irreversible changes to body tissues.

The author explains that NSAIDs produce their anti-inflammatory effects through three mechanisms: inhibiting prostaglandin production, suppressing white blood cell migration to the injury site, and blocking oxygen free radicals. In animal models, NSAIDs showed short-term benefits after acute injury, including faster reduction of swelling and pain. However, the same studies also revealed long-term adverse effects on tissue structure and function, suggesting that while NSAIDs can accelerate initial recovery, they may compromise the quality of the healed tissue over time. The review found that retardation of inflammatory processes after acute injury may limit the area of secondary tissue damage, which is beneficial, but may also retard the overall healing process. Clinical trials of NSAIDs for acute soft tissue injuries showed conflicting results, and the studies have been criticized for methodological limitations. NSAIDs showed few benefits for delayed-onset muscle soreness specifically. The author concludes that the short-term benefits of NSAIDs in treating acute soft tissue injuries must be weighed against the potential long-term adverse effects on tissue healing, structure, and function.

When tendon cells from diseased tissue were stimulated with an inflammatory trigger, they released large amounts of PGE2, while cells from healthy tendons did not. The researchers determined that PGE2 sustains inflammation and pain in tendon disease, while prostacyclin appears to have a protective role. Importantly, when diseased tendon cells were treated with naproxen, a standard NSAID, both PGE2 and prostacyclin production were inhibited. This study provides direct molecular evidence that the inflammatory pathway targeted by NSAIDs is active and driving pain in tendinopathy. The COX enzymes that NSAIDs inhibit are upregulated in diseased tendons, and the PGE2 they produce is responsible for sustaining the inflammatory cycle.
