Treatment of tendon injuries is largely conservative. Use of non-steroidal anti-inflammatory drugs (NSAIDs), rest, and gradual return to exercise is a common therapy. Resting assists in the prevention of further damage to the tendon. Ice, compression and elevation are also frequently recommended. Physical therapy, occupational therapy, orthotics or braces may also be useful. Initial recovery is typically within 2 to 3 days and full recovery is within 3 to 6 months. Tendinosis occurs as the acute phase of healing has ended (6–8 weeks) but has left the area insufficiently healed. Treatment of tendinitis helps reduce some of the risks of developing tendinosis, which takes longer to heal.

Steroid injections have not been shown to have long term benefits but have been shown to be more effective than NSAIDs in the short term.

In chronic tendinitis or tendonosis laser therapy has been found to be better than conservative treatment at reducing pain; however, no other outcomes were assessed.

Both prolotherapy and PRP injections are being used more frequently with good clinical short and long term outcomes in tendonosis - research has been only slightly positive for these treatment modalities due to the poor design of many of the completed studies.

Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to treat PFPS, however there is only very limited evidence that they are effective. NSAIDs may reduce pain in the short term, overall however, after three months pain is not improved. There is no evidence that one type of NSAID is superior to another in PFPS, and therefore some authors have recommended that the NSAID with fewest side effects and which is cheapest should be used.

Glycosaminoglycan polysulfate (GAGPS) inhibits proteolytic enzymes and increases synthesis and degree of polymerization of hyaluronic acid in synovial fluid. There is contradictory evidence that it is effective in PFPS.

Treatment is possible with ice, cold compression therapy, wearing heel pads to reduce the strain on the tendon, and an exercise routine designed to strengthen the tendon (see eccentric strengthening, above). Some people have reported vast improvement after applying light to medium compression around ankles and lower calf by wearing elastic bandages throughout the day. Using these elastic bandages while sleeping can reduce morning stiffness but care must be taken to apply very light compression during sleep. Compression can inhibit healing by hindering circulation. Seeing a professional for treatment as soon as possible is important, because this injury can lead to an Achilles tendon rupture with continued overuse. Other treatments may include non-steroidal anti-inflammatory drugs, such as ibuprofen, ultrasound therapy, manual therapy techniques, a rehabilitation program, and in rare cases, application of a plaster cast. Steroid injection is sometimes used, but must be done after very careful, expert consideration because it can increase the risk of tendon rupture. There has recently been some interest in the use of autologous blood injections; however the results have not been highly encouraging and there is little evidence for their use.

More specialised therapies include prolotherapy (sclerosant injection into the neovascularity) and extracorporeal shockwave therapy may have some additional benefit. However, the evidence is limited.

As patellofemoral pain syndrome is the most common cause of anterior knee pain in the outpatient, a variety of treatments for patellofemoral pain syndrome are implemented. Most patients with patellofemoral pain syndrome respond well to conservative therapy.

Although anti-inflammatories are a commonly prescribed treatment for tennis elbow, the evidence for their effect is usually anecdotal with only limited studies showing a benefit. A systematic review found that topical non-steroidal anti-inflammatory drugs (NSAIDs) may improve pain in the short term (up to 4 weeks) but was unable to draw firm conclusions due to methodological issues. Evidence for oral NSAIDs is mixed.

Evidence is poor for long term improvement from injections of any type, whether corticosteroids, botulinum toxin, prolotherapy or other substances. Corticosteroid injection may be effective in the short term however are of little benefit after a year, compared to a wait-and-see approach. A recent randomized control trial comparing the effect of corticosteroid injection, physiotherapy, or a combination of corticosteroid injection and physiotherapy found that patients treated with corticosteroid injection versus placebo had lower complete recovery or improvement at 1 year (Relative risk 0.86). Patients that received corticosteroid injection also had a higher recurrence rate at 1 year versus placebo (54% versus 12%, relative risk 0.23).

Complications from repeated steroid injections include skin problems such as hypopigmentation and fat atrophy leading to indentation of the skin around the injection site. Botulinum toxin type A to paralyze the forearm extensor muscles in those with chronic tennis elbow that has not improved with conservative measures may be viable.

Evidence for the treatment of lateral epicondylitis before 2010 was poor. There were clinical trials addressing many proposed treatments, but the trials were of poor quality.

In some cases, severity of tennis elbow symptoms mend without any treatment, within six to 24 months. Tennis elbow left untreated can lead to chronic pain that degrades quality of daily living.

Injections are usually focused on the iliopsoas bursa. Corticosteroid injections are common, but usually only last weeks to months. In addition, corticosteroid side effects can include weight gain, weakening of the surrounding tissues, and more. Cellular based therapy may have a role in future injection based treatments, though there is no current research proving the effectiveness of these therapies.

Patients may require intermittent NSAID therapy or simple analgesics as they progress in activities. If persistent pain caused by bursitis continues a corticosteroid injection may be beneficial.

Steroid injections are helpful in the short term (first approximately 4 weeks) however, their long term effectiveness is not known, and quality of evidence for its use remains poor and controversial.

Other, more conservative and non-surgical, treatment options available for the management and treatment of tendinopathy include: rest, ice, massage therapy, eccentric exercise, NSAIDs, ultrasound therapy, LIPUS, electrotherapy, taping, sclerosing injections, blood injection, glyceryl trinitrate patches, and (ESWT) extracorporeal shockwave therapy. Studies with a rat model of fatigue-damaged tendons suggested that delaying exercise until after the initial inflammatory stage of repair could promote remodelling more rapidly. There is insufficient evidence on the routine use of injection therapies (Autologous blood, Platelet-rich plasma, Deproteinised haemodialysate, Aprotinin, Polysulphated glycosaminoglycan, Corticosteroid, Skin derived fibroblasts etc.) for treating Achilles tendinopathy. As of 2014 there was insufficient evidence to support the use of platelet-rich therapies for treating musculoskeletal soft tissue injuries such as ligament, muscle and tendon tears and tendinopathies.

Many non-operative treatments have been advocated, including rest; oral administration of non-steroidal anti-inflammatory drugs; physical therapy; chiropractic; and local modalities such as cryotherapy, ultrasound, electromagnetic radiation, and subacromial injection of corticosteroids.

Shoulder bursitis rarely requires surgical intervention and generally responds favorably to conservative treatment. Surgery is reserved for patients who fail to respond to non-operative measures. Minimally invasive surgical procedures such as arthroscopic removal of the bursa allows for direct inspection of the shoulder structures and provides the opportunity for removal of bone spurs and repair of any rotator cuff tears that may be found.

Early stages may be treated conservatively using the R.I.C.E methods.

1. Rest

2. Ice

3. Compression

4. Elevation

Exercises involving eccentric muscle contractions of the quadriceps on a decline board are strongly supported by extant literature. A physical therapist may also recommend specific exercises and stretches to strengthen the muscles and tendons, eg. cycling or swimming. Use of a strap for jumper's knee and suspension inlays for shoes may also reduce the problems.

Should this fail, autologous blood injection, or platelet-rich plasma injection may be performed and is typically successful though not as successful as high volume saline injection (Crisp "et al."). Uncommonly it may require surgery to remove myxoid degeneration in the tendon. This is reserved for patients with debilitating pain for 6–12 months despite conservative measures. Novel treatment modalities targeting the abnormal blood vessel growth which occurs in the condition are currently being investigated.

New research shows that knee operations in most cases have no better effects than exercise programs, and that most knee operations thus can be avoided.

Early on arthritis of the shoulder can be managed with mild analgesics and gentle exercises.

Known gentle exercises include warm water therapy pool exercises that are provided by a trained and licensed physical therapist; approved land exercises to assure free movement of the arthritic area; cortisone injections (administered at the minimum of every six months according to orthopedic physicians) to reduce inflammation; ice and hot moist pact application are very effective. Moist heat is preferred over ice whereas ice is preferred if inflammation occurs during the daytime hours. Local analgesics along with ice or moist heat are adequate treatments for acute pain.

In the case of rheumatoid arthritis, specific medications selected by a rheumatologist may offer substantial relief.

When exercise and medication are no longer effective, shoulder replacement surgery for arthritis may be considered. In this operation, a surgeon replaces the shoulder joint with an artificial ball for the top of the humerus and a cap (glenoid) for the scapula. Passive shoulder exercises (where someone else moves the arm to rotate the shoulder joint) are started soon after surgery. Patients begin exercising on their own about 3 to 6 weeks after surgery. Eventually, stretching and strengthening exercises become a major part of the rehabilitation programme. The success of the operation often depends on the condition of rotator cuff muscles prior to surgery and the degree to which the patient follows the exercise programme.

In young and active patients a partial shoulder replacement with a non-prosthetic glenoid arthroplasty may also be a consideration .

Analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) are useful to a limited extent. Corticosteroid injections may be useful when the shoulder is acutely inflamed but otherwise are not generally useful except for the temporary relief of pain.

Anti-inflammatory medicines such as aspirin, naproxen or ibuprofen among others can be taken to help with pain. In some cases the physical therapist will use ultrasound and electrical stimulation, as well as manipulation. Gentle stretching and strengthening exercises are added gradually. If there is no improvement, the doctor may inject a corticosteroid medicine into the space under the acromion. However, recent level one evidence showed limited efficacy of corticosteroid injections for pain relief. While steroid injections are a common treatment, they must be used with caution because they may lead to tendon rupture. If there is still no improvement after 6 to 12 months, the doctor may perform either arthroscopic or open surgery to repair damage and relieve pressure on the tendons and bursae.

In those with calcific tendinitis of the shoulder high energy extracorporeal shock-wave therapy can be useful. It is not useful in other types of tendonitis.

Those suspected of having a rotator cuff tear are potentially candidates for either operative or non-operative treatment. However, any individual may move from one group to the other based on clinical response and findings on repeated examination.

No evidence of benefit is seen from early rather than delayed surgery, and many with partial tears and some with complete tears will respond to nonoperative management. Consequently, many recommend initial, nonsurgical management. However, early surgical treatment may be considered in significant (>1 cm-1.5 cm) acute tears or in young patients with full-thickness tears who have a significant risk for the development of irreparable rotator cuff changes.

Finally, a review of more than 150 published papers in 2010 concluded that no solid evidence indicated rotator-cuff surgery benefited patients more than nonoperative management, adding to management and treatment controversies.

Usually it improves without specific treatment. Treatments of calcific tendinitis may include physiotherapy, NSAIDs, or steroid injections. If these do not work extracorporeal shock wave therapy or surgery may be considered.

Deteriorating changes start to appear with age, but attempting to slow down these changes is key in the prevention of Achilles tendinitis. Performing consistent physical activity will improve the elasticity and strength of the tendon, which will assist in resisting the forces that are applied.

It is essential to stretch and warm-up before beginning an exercise session in order to prepare and protect the tendon for work. Warm-ups enhance the tendon's capability of being stretched, further aiding in protection from injury. Prevention of recurrence includes following appropriate exercise habits and wearing low-heeled shoes. In the case of incorrect foot alignment, orthotics can be used as a preventative way to properly position the feet. Footwear that is specialized to provide shock-absorption can be utilized to defend the longevity of the tendon. Achilles tendon injuries can be the result of exceeding the tendon's capabilities for loading, therefore it is important to gradually adapt to exercise if someone is inexperienced, sedentary, or is an athlete who is not progressing at a steady rate.

Preventive exercises are aimed at strengthening the gastrocnemius and soleus muscles, typically by eccentric strengthening exercises. This eccentric training method is especially important for individuals with chronic Achilles tendinosis which is classified as the degeneration of collagen fibers. Eccentric exercises improve the tensile strength of the tendon and lengthen the muscle-tendon junction, decreasing the amount of strain experienced with ankle joint movements. These involve repetitions of slowly raising and lowering the body while standing on the affected leg, using the opposite arm to assist balance and support if necessary, and starting with the heel in a hyperextended position. (Hyperextension is typically achieved by balancing the forefoot on the edge of a step, a thick book, or a barbell weight. so that the point of the heel is a couple of inches below the forefoot.)

One study found increased achilles tendon healing in rats supplemented with high doses of vitamin C, which is needed for collagen synthesis.

Both eccentric loading and extracorporeal shockwave therapy are currently being researched as possible treatments for tendinosis. One study found both modalities to be equally effective in treating tendinosis of the Achilles tendon and more effective than a 'wait and see' approach. Other treatments for which research is on-going includes vitamin E, vitamin B6, nitric oxide, Platelet Rich Plasma (PRP), and stem cell injections.

Those with pain but reasonably maintained function are suitable for nonoperative management. This includes oral medications that provide pain relief such as anti-inflammatory agents, topical pain relievers such as cold packs, and if warranted, subacromial corticosteroid/local anesthetic injection. An alternative to injection is iontophoresis, a battery-powered patch which "drives" the medication to the target tissue. A sling may be offered for short-term comfort, with the understanding that undesirable shoulder stiffness can develop with prolonged immobilization. Early physical therapy may afford pain relief with modalities (e.g. iontophoresis) and help to maintain motion. Ultrasound treatment is not efficacious. As pain decreases, strength deficiencies and biomechanical errors can be corrected.

A conservative physical therapy program begins with preliminary rest and restriction from engaging in activities which gave rise to symptoms. Normally, inflammation can usually be controlled within one to two weeks, using a nonsteroidal anti-inflammatory drug and subacromial steroid injections to decrease inflammation, to the point that pain has been significantly decreased to make stretching tolerable. After this short period, rapid stiffening and an increase in pain can result if sufficient stretching has not been implemented.

A gentle, passive range-of-motion program should be started to help prevent stiffness and maintain range of motion during this resting period. Exercises, for the anterior, inferior, and posterior shoulder, should be part of this program. Codman exercises (giant, pudding-stirring), to "permit the patient to abduct the arm by gravity, the supraspinatus remains relaxed, and no fulcrum is required" are widely used. The use of NSAIDs, hot and cold packs, and physical therapy modalities, such as ultrasound, phonophoresis, or iontophoresis, can be instituted during this stretching period, if effective. Corticosteroid injections are recommended two to three months apart with a maximum of three injections. Multiple injections (four or more) have been shown to compromise the results of rotator cuff surgery which result in weakening of the tendon. However, before any rotator cuff strengthening can be started, the shoulder must have a full range of motion.

After a full, painless range of motion is achieved, the patient may advance to a gentle strengthening program. Rockwood coined the term orthotherapy to describe this program which is aimed at creating an exercise regimen that initially gently improves motion, then gradually improves strength in the shoulder girdle. Each patient is given a home therapy kit, which includes elastic bands of six different colors and strengths, a pulley set, and a three-piece, one-meter-long stick. The program is customized, fitting the needs of the individual and altering when necessary. Participants are asked to use their exercise program whether at home, work, or traveling.

Several instances occur in which nonoperative treatment would not be suggested:

- 20 to 30-year-old active patient with an acute tear and severe functional deficit from a specific event

- 30 to 50-year-old patient with an acute rotator cuff tear secondary to a specific event

- a highly competitive athlete who is primarily involved in overhead or throwing sports

These patients may need to be treated operatively because rotator cuff repair is necessary for restoration of the normal strength required to return to the preoperative, competitive level of function. Finally, those who do not respond to, or are unsatisfied with, conservative treatment should seek a surgical opinion.

Medication is not the primary treatment for hypermobility, but can be used as an adjuct treatment for related joint pain. NSAIDS are the primary medications of choice. Narcotics are not recommended for primary or long term treatment and are reserved for short term use after acute injury.

The most-often prescribed treatments for early-stage RSIs include analgesics, myofeedback, biofeedback, physical therapy, relaxation, and ultrasound therapy. Low-grade RSIs can sometimes resolve themselves if treatments begin shortly after the onset of symptoms. However, some RSIs may require more aggressive intervention including surgery and can persist for years.

General exercise has been shown to decrease the risk of developing RSI. Doctors sometimes recommend that RSI sufferers engage in specific strengthening exercises, for example to improve sitting posture, reduce excessive kyphosis, and potentially thoracic outlet syndrome. Modifications of posture and arm use (human factors and ergonomics) are often recommended.

In patients with bursitis who have rheumatoid arthritis, short term improvements are not taken as a sign of resolution and may require long term treatment to ensure recurrence is minimized. Joint contracture of the shoulder has also been found to be at a higher incidence in type two diabetics, which may lead to frozen shoulder (Donatelli, 2004).

In horses tendinitis is called a bowed tendon from the appearance of the affected tendon after it heals without treatment. Mesenchymal stem cells, derived from a horse's bone marrow or fat, are currently being used for tendon repair in horses.

This method should be used within the first 48–72 hours after the injury in order to speed up the recovery process.

Heat: Applying heat to the injured area can cause blood flow and swelling to increase.

Alcohol: Alcohol can inhibit your ability to feel if your injury is becoming more aggravated, as well as increase blood flow and swelling.

Re-injury: Avoid any activities that could aggravate the injury and cause further damage.

Massage: Massaging an injured area can promote blood flow and swelling, and ultimately do more damage if done too early.
