The first-line treatment for a muscular strain in the acute phase include five steps commonly known as P.R.I.C.E.

- Protection: Apply soft padding to minimize impact with objects.

- Rest: Rest is necessary to accelerate healing and reduce the potential for re-injury.

- Ice: Apply ice to induce vasoconstriction, which will reduce blood flow to the site of injury. Never ice for more than 20 minutes at a time.

- Compression: Wrap the strained area with a soft-wrapped bandage to reduce further diapedesis and promote lymphatic drainage.

- Elevation: Keep the strained area as close to the level of the heart as is possible in order to promote venous blood return to the systemic circulation.

Immediate treatment is usually an adjunctive therapy of NSAID's and Cold compression therapy. Controlling the inflammation is critical to the healing process. Cold compression therapy acts to reduce swelling and pain by reducing leukocyte extravasation into the injured area. NSAID's such as Ibuprofen/paracetamol work to reduce the immediate inflammation by inhibiting Cox-1 & Cox-2 enzymes, which are the enzymes responsible for converting arachidonic acid into prostaglandin. However, NSAIDs, including aspirin and ibuprofen, affect platelet function (this is why they are known as "blood thinners") and should not be taken during the period when tissue is bleeding because they will tend to increase blood flow, inhibit clotting, and thereby increase bleeding and swelling. After the bleeding has stopped, NSAIDs can be used with some effectiveness to reduce inflammation and pain.

A new treatment for acute strains is the use of platelet rich plasma (PRP) injections which have been shown to accelerate recovery from non surgical muscular injuries.

It is recommended that the person injured should consult a medical provider if the injury is accompanied by severe pain, if the limb cannot be used, or if there is noticeable tenderness over an isolated spot. These can be signs of a broken or fractured bone, a sprain, or a complete muscle tear.

Prompt medical treatment should be sought for suspected dislocation.

Usually, the shoulder is kept in its current position by use of a splint or sling. A pillow between the arm and torso may provide support and increase comfort. Strong analgesics are needed to allay the pain of a dislocation and the distress associated with it.

Treatment is generally conservative with rest, ice, and specific exercises being recommended. Simple pain killers may be used if required such as acetaminophen (paracetamol) or ibuprofen. Typically symptoms resolve as the growth plate closes. Physiotherapy is generally recommended once the initial symptoms have improved to prevent recurrence. Surgery may rarely be used in those who have stopped growing yet still have symptoms.

Shoulder reduction may be accomplished with a number of techniques including traction-countertraction, external rotation, scapular manipulation, Stimson technique, Cunningham technique, or Milch technique. Pain can be managed during the procedures either by procedural sedation and analgesia or injected lidocaine into the shoulder joint. Injecting lidocaine into the joint may be less expensive and faster. If a shoulder cannot be relocated in the emergency room, relocation in the operating room maybe required. This situation occurs in about 7% of cases.

If the fracture is small, it is usually sufficient to treat with rest and support bandage, but in more severe cases, surgery may be required. Ice may be used to relieve swelling.

Displaced avulsion fractures are best managed by either open reduction and internal fixation or closed reduction and pinning. Open reduction (using surgical incision) and internal fixation is used when pins, screws, or similar hardware is needed to fix the bone fragment.

Two types of treatment options are typically available:

- Surgery

- Conservative treatment (rehabilitation and physical therapy)

Surgery may impede normal growth of structures in the knee, so doctors generally do not recommend knee operations for young people who are still growing. There are also risks of complications, such as an adverse reaction to anesthesia or an infection.

When designing a rehabilitation program, clinicians consider associated injuries such as chipped bones or soft tissue tears. Clinicians take into account the person's age, activity level, and time needed to return to work and/or athletics. Doctors generally only recommend surgery when other structures in the knee have sustained severe damage, or specifically when there is:

- Concurrent osteochondral injury

- Continued gross instability

- Palpable disruption of the medial patellofemoral ligament and the vastus medialis obliquus

- High-level athletic demands coupled with mechanical risk factors and an initial injury mechanism not related to contact

Supplements like glucosamine and NSAIDs can be used to minimize bothersome symptoms.

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.

An effective rehabilitation program reduces the chances of reinjury and of other knee-related problems such as patellofemoral pain syndrome and osteoarthritis. Rehabilitation focuses on maintaining strength and range of motion to reduce pain and maintain the health of the muscles and tissues around the knee joint.

Treatment options for distal radius fractures include non-operative management, external fixation, and internal fixation. Indications for each depend on a variety of factors such as patient's age, initial fracture displacement, and metaphyseal and articular alignment, with the ultimate goal to maximize strength, and function in the affected upper extremity. Surgeons use these factors combined with radiologic imaging to predict fracture instability, and functional outcome in order to help decide which approach would be most appropriate. Treatment is often directed to restore normal anatomy to avoid the possibility of malunion, which may cause decreased strength in the hand and wrist. The decision to pursue a specific type of management varies greatly by geography, physician specialty (hand surgeons vs. orthopedic surgeons), and advancements in new technology such as the volar locking plating system.

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.

One of the main ways to prevent OSD is to check the participant's flexibility in their quadriceps and hamstrings. Lack of flexibility in these muscles can be direct risk indicator for OSD. Muscles can shorten, which can cause pain but this is not permanent. Stretches can help reduce shortening of the muscles. The main stretches for prevention of OSD focus on the hamstrings and quadriceps.

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.

This condition is usually curable with appropriate treatment, or sometimes it heals spontaneously. If it is painless, there is little cause for concern.

Correcting any contributing biomechanical abnormalities and stretching tightened muscles, such as the iliopsoas muscle or iliotibial band, is the goal of treatment to prevent recurrence.

Referral to an appropriate professional for an accurate diagnosis is necessary if self treatment is not successful or the injury is interfering with normal activities. Medical treatment of the condition requires determination of the underlying pathology and tailoring therapy to the cause. The examiner may check muscle-tendon length and strength, perform joint mobility testing, and palpate the affected hip over the greater trochanter for lateral symptoms during an activity such as walking.

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.

The term for non-surgical treatment for ACL rupture is "conservative management", and it often includes physical therapy and using a knee brace. Instability associated with ACL deficiency increases the risk of other knee injuries such as a torn meniscus, so sports with cutting and twisting motions are problematic and surgery is often recommended in those circumstances.

Patients who have suffered an ACL injury should be evaluated for other injuries that often occur in combination with an ACL tear and include cartilage/meniscus injuries, bone bruises, PCL tears, posterolateral injuries and collateral ligament injuries. When a combination injury occurs, surgical treatment is usually advised.

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.

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.

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.

Treatment of posterolateral corner injuries varies with the location and grade of severity of the injuries. Patients with grade I and II (partial) injuries to the posterolateral corner can usually be managed conservatively. Studies have reported that patients with grade III (complete) injuries do poorly with conservative management and typically will require surgical intervention followed by rehabilitation.

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.

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

Usually treated with a splint placing the proximal interphalangeal joint in extension for 4–6 weeks. Occasionally surgery is needed when splinting is unsuccessful.

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.

Vasodilators improve the blood flow into the vessels of the hoof. Examples include isoxsuprine (currently unavailable in the UK) and pentoxifylline.

Anticoagulants can also improve blood flow. The use of warfarin has been proposed, but the extensive monitoring required makes it unsuitable in most cases.

Anti-inflammatory drugs are used to treat the pain, and can help the lameness resolve sometimes if shoeing and training changes are made. Include Nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and other joint medications. The use of intramuscular glycosaminoglycans has been shown to decrease pain in horses with navicular disease, but this effect wanes after discontinuation of therapy. Oral glycosaminoglycans may have a similar effect.

Bisphosphonates can be useful in cases where bone remodeling is causing pain.

Gallium nitrate (GaN) has been hypothesized as a possible treatment for navicular disease, but its benefits have not been confirmed by formal clinical studies. One pilot study examined horses given gallium nitrate in their feed rations. While it was absorbed slowly, it did stay in the animals' system, providing a baseline dosage for future studies.

Non-surgical treatment is for extra-articular fractures and Sanders Type I intra-articular fractures, provided that the calcaneal weight-bearing surface and foot function are not compromised. Physicians may choose to perform closed reduction with or without fixation (casting), or fixation alone (without reduction), depending on the individual case. Recommendations include no weight-bearing for a few weeks followed by range-of-motion exercises and progressive weight bearing for a period of 2–3 months.

Displaced intra-articular fractures require surgical intervention within 3 weeks of fracture, before bone consolidation has occurred. Conservative surgery consists of closed reduction with percutaneous fixation. This technique is associated with less wound complications, better soft tissue healing (because of less soft tissue manipulati) and decreased intraoperative time. However, this procedure has increased risk of inadequate calcaneal bone fixation, compared to open procedures. Currently, open reduction with internal fixation (ORIF) is usually the preferred surgical approach when dealing with displaced intra-articular fractures. Newer, more innovative surgical techniques and equipment have decreased the incidence of intra- and post-operative complications.
