The technique raises deep tissue temperatures between 41°C and 45°C using electromagnetic power and has been widely used in physical medicine and sports traumatology. Research findings indicate that microwave diathermy stimulates tissue repair, enhances drug activity, alleviates pain, aids in waste removal, increases tendon extensibility, and reduces muscle and joint stiffness. The therapy also promotes hyperaemia, improves tissue drainage, accelerates metabolism, and induces cellular changes. While the exact biological mechanisms linking thermal dose to healing remain under investigation, microwave diathermy at 434 and 915 MHz has shown short-term effectiveness in managing musculoskeletal injuries.",

Three groups were compared: a control group (no ultrasound), a once-daily (qd) treatment group, and a twice-daily (bid) treatment group. Results showed that the bid group exhibited significantly greater new bone formation, mineralization, fibrocartilage development, and improved mechanical properties at the healing site compared to the other groups. Findings suggest that twice-daily LIPUS treatment is more effective for enhancing tendon-bone healing than a once-daily treatment.",

Ligament extensibility was measured using a KT2000 arthrometer, and the force required for knee flexion was assessed using continuous passive motion (CPM). Results showed that heat increased the flexibility of the anterior and posterior cruciate ligaments and reduced the force required for knee flexion by about 25%, while cold had the opposite effect. These findings suggest that heat therapy may enhance flexibility and reduce injury risk, whereas cold therapy may restrict movement.",

Notably, athletes with a history of repetitive mechanical stress exhibited a proliferation of immature connective tissue and impaired healing capacity. These findings support the idea that excess mechanical loading during the healing cycle can be harmful and contribute to chronic injury.",

The researchers added the steroid to the culture medium of isolated human supraspinatus tendon cells and observed the effects over 2 weeks. The findings were striking. 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. Additionally, the steroid caused the tendon cells to transform into fat cells and cartilage-like cells rather than maintaining their normal tendon phenotype. These results provide direct cellular evidence that corticosteroid injections may weaken tendons and contribute to the high rate of re-rupture after rotator cuff repair, supporting the recommendation to approach cortisone injections with caution.",

            "summary": "This clinical review examined the management of chronic tendon injuries, which are common in both athletic and occupational settings. 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. This aligns with the concept that NSAIDs are a tool to support recovery when used with proper timing and dose control, not a substitute for addressing the underlying injury.",

The researchers identified that the major arteries supplying the rotator cuff come from several branches around the shoulder. Most importantly, they found a \"critical zone\" in the supraspinatus tendon where blood supply is naturally limited. This area of poor circulation is believed to contribute significantly to the wear and degeneration of the tendon as we age, making it harder for the body to heal injuries in this region. The findings support the importance of stimulating blood flow to the rotator cuff to support healing, especially in areas where natural circulation is already compromised.",

Major adverse events, which required intervention or did not resolve, included serious infections such as osteomyelitis and cellulitis, one fatal case of necrotizing fasciitis, tendon ruptures, skin atrophy, hypopigmentation, and local skin defects. The incidence of major adverse events ranged from 0 to 5.8% across studies. Minor adverse events, which were transient and did not require intervention, ranged from skin rash to flushing and disturbed menstrual patterns, with incidence as high as 81% in some studies. Increased pain or steroid flare after injection was reported in 19 studies. The review confirms that corticosteroid injections, while commonly used for pain relief, carry meaningful risks including tendon rupture, tissue atrophy, and serious infection. These findings support the recommendation that patients should be educated about these risks and encouraged to seek a second opinion before proceeding with corticosteroid injections, particularly when the injection is targeting tendon or ligament tissue that could be weakened by the steroid.",

The review identified 8 articles reporting adverse outcomes. The findings showed that even a single corticosteroid injection was associated with an increased risk of requiring revision rotator cuff repair, with odds ratios ranging from 1.3 to 2.8 when administered up to a year before surgery. The risk of adverse outcomes was greatest when injections were administered within 6 months of surgery, with an odds ratio of 1.8. Receiving 2 or more injections within a year of surgery further increased the risk, with odds ratios ranging from 2.1 to 3.3. Corticosteroid injections within one month of surgery also increased the risk of postoperative infection, with an odds ratio of 2.1. The study demonstrates that corticosteroid injections have a temporal and dose-dependent negative effect on rotator cuff tendon health and surgical outcomes. These findings support the recommendation that corticosteroid injections should be approached with caution, particularly when surgery may be needed, and that multiple injections should be avoided. Patients should be informed of these risks and encouraged to discuss alternatives with their physician.",

Using ultrasound imaging, researchers assessed ligament elasticity, nerve conduction velocity, and structural changes. Heat therapy (60-120 minutes) increased ligament and tendon elasticity, while cold exposure (20 minutes) reduced compression of the carpal ligament and nerve. Pressure did not significantly alter tissue structure at room temperature or after cold exposure. The findings suggest that heat enhances tissue flexibility, whereas cold may help reduce compression in conditions like carpal tunnel syndrome.",

Fresh frozen human tendons were subjected to heat in a saline solution, demonstrating a predictable shrinkage curve. A sharp increase in shrinkage (up to 70% of the original length) was observed around 70°C. Additionally, an Nd:YAG laser was used to induce precise, dose-dependent collagen shortening. Tendons shortened by 10% exhibited a significant decrease in load-to-failure strength (to about one-third of control specimens). Histological analysis revealed distinct thermal denaturation zones while preserving adjacent collagen. These findings suggest that collagen can be precisely shortened using heat, though further research is needed to assess biological responses, including recollagenization and long-term biomechanical effects.",

The cumulative effect of this repeated microtrauma can lead to scar formation and chronic dysfunction, making full recovery more difficult.

It presents evidence that prolonged immobilization can be detrimental, weakening normal tissues and delaying healing. At the same time, it cautions that premature or excessive motion and loading during the early phases of repair can halt or inhibit recovery. The author explains that repair tissues—particularly in tendons and ligaments—are often more sensitive to mechanical stress than mature, healthy tissues. While controlled, gradual reintroduction of motion may support healing, the study strongly emphasizes the need to avoid early overstressing of healing structures. These insights directly support the importance of limiting mechanical strain during the recovery of soft tissue injuries.",

The findings reveal an important distinction between types of NSAIDs. The majority of studies, including 1 of 2 human studies, 10 of 14 animal studies, and 3 of 3 in vitro studies, demonstrated that COX-2-selective inhibitors (such as celecoxib) had a negative impact on soft tissue healing. In contrast, the majority of studies showed that nonselective COX inhibitors (such as ibuprofen) had no negative effect on the healing of labrum, tendons, and ligaments. In vitro studies showed that NSAIDs generally have a harmful effect on the biological processes involved in tendon healing, including tenocyte proliferation and collagen synthesis. This study supports the nuanced position that not all NSAIDs affect healing equally. The anti-inflammatory properties of nonselective NSAIDs may benefit conditions involving tendons, ligaments, and cartilage where inflammation increases reinjury risk, while COX-2 selective inhibitors should be avoided during healing. These findings highlight the importance of understanding which specific medication a patient is taking and how it may interact with their recovery from a soft tissue injury.",

The review found that there is insufficient evidence of a detrimental effect when using either NSAIDs or COX-2 inhibitors at standard doses for 2 weeks or less on soft tissue healing. However, for soft tissue to bone healing, a limited number of studies did demonstrate impairment. With respect to bone healing, indomethacin showed a clear detrimental effect, with less substantial evidence for other NSAIDs. The study concludes that short-term, low-dose use of NSAIDs does not appear to harm soft tissue recovery following injury, but is inhibitory in cases where bone healing is required. This distinction is clinically important because it demonstrates that NSAIDs can be used selectively depending on the type of tissue being treated. For soft tissue injuries such as tendon, ligament, and muscle injuries, short-term NSAID use may be appropriate to manage inflammation. However, when bone healing is involved, such as fractures or spinal fusion, NSAIDs should be avoided. The review emphasizes that the prudent use of anti-inflammatory medications following sports medicine injuries is a reasonable option unless bone healing is a concern.",

The study found that corticosteroid injections reduced pain in the short term (within 4 weeks) compared to other interventions, showing a large effect size. However, this benefit was reversed at intermediate term (13 to 26 weeks) and long term (52 weeks and beyond). For example, in treating lateral epicondylalgia (tennis elbow), corticosteroid injections showed a large positive effect in the short term but actually performed worse than no intervention at all by the intermediate and long-term follow-up. This means that patients who received corticosteroid injections were ultimately worse off than if they had done nothing. The study also found that the short-term efficacy for rotator cuff tendinopathy was not clear. Among 991 participants who received corticosteroid injections, one case of tendon rupture was reported. These findings demonstrate that while corticosteroid injections provide temporary pain relief, they do not support long-term healing and may actually delay recovery. The reversal of benefit over time is consistent with the concern that pain masking leads to further tissue damage, as patients overuse the injured area while unable to feel the warning signs of strain.",

The review found that topical NSAIDs were significantly more effective than placebo for short-term pain relief, with a number needed to treat of 7, meaning that for every 7 patients treated with topical NSAIDs, one additional patient experienced significant pain relief compared to placebo. Participants using topical NSAIDs also reported better overall treatment effectiveness at 28 days. Adverse effects from topical NSAIDs were minimal, with only mild skin reactions such as rash reported in 2.5% of users, compared to 1.3% with placebo. For oral NSAIDs, the evidence was conflicting. One trial found significant pain improvement compared to placebo while another found no difference, and neither showed improvement in function. Notably, oral NSAIDs were associated with an increased risk of gastrointestinal side effects, and several participants had to discontinue treatment due to GI issues. The review found no trials that directly compared topical and oral NSAIDs head to head. These findings support the use of topical NSAIDs as a first-line option for conditions like tennis elbow, where the anti-inflammatory medication can be delivered directly to the injured tendon without exposing the gastrointestinal system to the risks associated with oral NSAIDs. For patients who do use oral NSAIDs, the evidence suggests limiting duration to the short term.",

The researchers examined tendon biopsies from patients with symptomatic tendinopathy or tendon rupture, as well as healthy comparator tendons. They found that diseased tendon tissue showed increased expression of enzymes responsible for producing prostaglandins, including COX-1 and COX-2, which are the exact enzymes that NSAIDs like ibuprofen work to block. 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. This supports the targeted use of NSAIDs to reduce PGE2-driven inflammation in tendon conditions, while also highlighting the importance of dose control to avoid suppressing the potentially protective prostacyclin pathway.",
