Outcomes vary depending on the location of the disease, the degree of damage to the joint, and whether surgical repair was necessary. Average healing times vary from 55–97 days depending on location. Up to 1–2 years may be required for complete healing.

Once the process is recognized, it should be treated via the VIPs — vascular management, infection management and prevention, and pressure relief. Aggressively pursuing these three strategies will progress the healing trajectory of the wound. Pressure relief (off-loading) and immobilization with total contact casting (TCC) are critical to helping ward off further joint destruction.

TCC involves encasing the patient’s complete foot, including toes, and the lower leg in a specialist cast that redistributes weight and pressure in the lower leg and foot during everyday movements. This redistributes pressure from the foot into the leg, which is more able to bear weight, to protect the wound, letting it regenerate tissue and heal. TCC also keeps the ankle from rotating during walking, which prevents shearing and twisting forces that can further damage the wound. TCC aids maintenance of quality of life by helping patients to remain mobile.

There are two scenarios in which the use of TCC is appropriate for managing neuropathic arthropathy (Charcot foot), according to the American Orthopaedic Foot and Ankle Society. First, during the initial treatment, when the breakdown is occurring, and the foot is exhibiting edema and erythema; the patient should not bear weight on the foot, and TCC can be used to control and support the foot. Second, when the foot has become deformed and ulceration has occurred; TCC can be used to stabilize and support the foot, and to help move the wound toward healing.

Walking braces controlled by pneumatics are also used. Surgical correction of a joint is rarely successful in the long-term in these patients. However, off-loading alone does not translate to optimal outcomes without appropriate management of vascular disease and/or infection. Duration and aggressiveness of offloading (non-weight-bearing vs. weight-bearing, non-removable vs. removable device) should be guided by clinical assessment of healing of neuropathic arthropathy based on edema, erythema, and skin temperature changes. It can take 6–9 months for the edema and erythema of the affected joint to recede.

Although a 2011 research article stated that disagreements between hand surgeons and rheumatologists remain regarding the indications, timing and effectiveness of rheumatoid hand surgery, arthritis mutilans may be successfully treated by iliac-bone graft and arthrodesis of the interphalangeal joints and the metacarpophalangeal joint in each finger.

The bone edema in arthitis mutilans can be treated with TNF inhibitors in the short term: a 2007 study found that the bone edema associated with psoriatic arthritis (of which arthitis mutilans is a subtype) responded to TNF inhibitors with "dramatic" improvement, but the study was not determinative of whether TNF inhibitors would prevent new bone formation, bone fusion, or osteolysis (bone resorption).

Two elements are considered: radiology and joint fluid analysis.

Radiology has a large role to play in finding chondrocalcinosis, with radiographs, CT scans, MRIs, US, and nuclear medicine all having a part. CT scans and MRIs show calcific masses (usually within the ligamentum flavum or joint capsule), however radiography is more successful. At ultrasound, chondrocalcinosis may be depicted as echogenic foci with no acoustic shadow within the hyaline cartilage. As with most conditions, CPPD can present with similarity to other diseases such as ankylosing spondylitis and gout.

Arthrocentesis, or removing synovial fluid from the affected joint, is performed to test the synovial fluid for the calcium pyrophosphate crystals that are present in CPPD. When stained with H&E stain, calcium pyrophosphate crystals appears deeply blue ("basophilic"). However, CPP crystals are much better known for their rhomboid shape and weak positive birefringence on polarized light microscopy, and this method remains the most reliable method of identifying the crystals under the microscope. However, even this method suffers from poor sensitivity, specificity, and inter-operator agreement.

These two modalities currently define CPPD disease but lack diagnostic accuracy, and are potentially epiphenomenological.

In order to qualify a patient's condition as BSS, the bending angle must be greater than 45 degrees. While the presence of the condition is very easy to note, the cause of the condition is much more difficult to discern. Conditions not considered to be BSS include vertebral fractures, previously existing conditions, and ankylosing spondylitis. Lower-back CT scans and MRIs can typically be used to visualize the cause of the disease. Further identification of the cause can be done by histochemical or cellular analysis of muscle biopsy.

Camptocormia is becoming progressively found in patients with Parkinson's disease.

The diagnosis of Parkinson's-associated camptocormia includes the use of imaging of the brain and the spinal cord, along with electromyography or muscle biopsies.

Muscle biopsies are also a useful tool to diagnose camptocormia. Muscle biopsies found to have variable muscle fiber sizes and even endomysial fibrosis may be markers of bent spine syndrome. In addition, disorganized internal architecture and little necrosis or regeneration is a marker of camptocormia.

Patients with camptocormia present with reduced strength and stooped posture when standing due to weakened paraspinous muscles (muscles parallel to the spine). Clinically, limb muscles show fatigue with repetitive movements. Paraspinous muscles undergo fat infiltration. Electromyography may be used as well in diagnosis. On average, the paraspinous muscles of affected individuals were found to be 75% myopathic, while limb muscles were 50% percent myopathic. Creatine kinase activity levels in skeletal muscle are a diagnostic indicator that can be identifiable through blood tests.

Hemarthrosis is diagnoised through below methods-

A physical examination is the first step, the joints of the patient are moved and bent to study the functioning.

Synovial Fluid analysis is another method to diagnose Hemarthrosis. It involves a small needle being inserted into the joint to draw the fluid. Reddish-colored hue of the sample is an indication of the blood being present. Imaging tests are normally done. The tests also include MRI, Ultrasound and X-ray test, which give better information about the joint inflammation.

Ultrasonography and magnetic resonance imaging of the hands and/or feet have been proposed as useful diagnostic investigations in RS3PE.

Some studies linked RS3PE to HLA-B27 whereas others have not.

Up to a quarter of all severe ligament or capsular knee injuries leading to a haemarthrosis are associated with cartilage damage that can lead to progressive degenerative arthritis.

An arthropathy is a disease of a joint. Arthritis is a form of arthropathy that involves inflammation of one or more joints, while the term arthropathy may be used regardless of whether there is inflammation or not.

Spondylarthropathy is any form of arthropathy of the vertebral column.

Because any medication that could reduce the inflammation of CPPD bears a risk of causing organ damage, treatment is not advised if the condition is not causing pain.

For acute pseudogout, treatments include intra-articular corticosteroid injection, systemic corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs), or, on occasion, high-dose colchicine. In general, NSAIDs are administered in low doses to help prevent CPPD. However, if an acute attack is already occurring, higher doses are administered. If nothing else works, hydroxychloroquine or methotrexate may provide relief.

Research into surgical removal of calcifications is underway, however this still remains an experimental procedure.

Due to the wide range of causes of camptocormia, there is no one treatment that suits all patients. In addition, there is no specific pharmacological treatment for primary BSS. The use of analgesic drugs depends entirely on the intensity of the back pain. Muscular-origin BSS can be alleviated by positive lifestyle changes, including physical activity, walking with a cane, a nutritious diet, and weight loss. Worsening of symptoms is possible but rare in occurrence.

Treatment of the underlying cause of the disease can alleviate the condition in some individuals with secondary BSS. Other treatment options include drugs, injections of botulinum toxin, electroconvulsive therapy, deep brain stimulation, and surgical correction. Unfortunately, many of the elderly individuals affected by the BSS are not treated surgically due to age-related physical ailments and the long postoperative recovery period.

Arthropathy may also include joint conditions caused by physical trauma to joints, but is traditionally used to describe the following conditions:

- "Reactive arthropathy" (M02-M03) is caused by an infection, but not a direct infection of the synovial space. (See also Reactive arthritis)

- "Enteropathic arthropathy" (M07) is caused by colitis and related conditions.

- "Crystal arthropathy" (also known as "crystal arthritis") (M10-M11) involves the deposition of crystals in the joint.

- In gout, the crystal is uric acid.

- In pseudogout/chondrocalcinosis/calcium pyrophosphate deposition disease, the crystal is calcium pyrophosphate.

- "Diabetic arthropathy" (M14.2, E10-E14) is caused by diabetes.

- "Neuropathic arthropathy" (M14.6) is associated with a loss of .

Jaccoud arthropathy (JA), Jaccoud deformity or Jaccoud's arthopathy is a chronic non-erosive reversible joint disorder that may occur after repeated bouts of arthritis. It is caused by inflammation of the joint capsule and subsequent fibrotic retraction, causing ulnar deviation of the fingers, through metacarpophalangeal joint (MCP) subluxation, primarily of the ring and little-finger. Joints in the feet, knees and shoulders may also get affected. It is commonly associated with systemic lupus erythematosus (SLE), and occurs in roughly 5% of all cases.

When associated with rheumatic fever it is also called chronic post–RF arthropathy.

Originally thought to be associated only with rheumatic fever, it has since been shown to occur also in SLE, Sjögren syndrome, scleroderma, dermatomyositis, psoriatic arthritis, vasculitis, ankylosing spondylitis, mixed connective tissue disease, and pyrophosphate deposition disease. It is distinct from bone erosion which is commonly associated with rheumatic arthritis, and also distinct from mild deforming arthropathy which is associated with SLE. There have also been cases of non-rheumatic JA associated with Lyme disease, HIV-infection and a number of other conditions.

Treatment focuses toward alleviating pain and in maintaining functionality of the affected joints through use of nonsteroidal anti-inflammatory drugs, corticosteroids, antimalarial drugs and physiotherapy. Surgery is also a possibility, with osteotomy or stabilization with Kirschner intramedullary wire. Tendon relocation, however, has been shown to only work in 30% of cases. The condition is named after the French 19th century physician Sigismond Jaccoud.

Remitting seronegative symmetrical synovitis with pitting edema (abbreviated RS3PE or sometimes RSPE) is a rare syndrome identified by symmetric polyarthritis, synovitis, acute pitting edema (swelling) of the back of the hands and/or feet, and a negative serum rheumatoid factor. If no underlying disorder can be identified (idiopathic RS3PE), this entity has an excellent prognosis and responds well to treatment.

RS3PE typically involves the joints of the extremities, specifically the metacarpophalangeal and proximal interphalangeal joints, wrists, shoulders, elbows, knees and ankles.

It is more common in older adults, with the mean age between 70 and 80 years in most studies.

It occurs more often in men than in women with a 2:1 ratio.

It is unknown how common this condition is.

While the clinical picture may point towards the diagnosis of the Roussy–Lévy syndrome, the condition can only be confirmed with absolute certainty by carrying out genetic testing in order to identify the underlying mutations.

Trochleitis is diagnosed based on three criteria: 1) demonstration of inflammation of superior oblique tendon/ trochlea region, 2) periorbital pain and tenderness to palpation in the area of the sore trochlea, and 3) worsening of pain on attempted vertical eye movement, particularly with adduction of the eye. It is important to identify trochleitis because it is a treatable condition and the patient can benefit much from pain relief. Treatment consists of a single injection of corticosteroids to the affected peritrochlear region. A specific "cocktail" consisting of 0.5 ml of depomedrol (80 mg/ml) and 0.5 ml of 2% lidocaine can be injected into the trochlea; immediate relief due to the effects of the local anesthetic indicates successful placement. However, great care must be taken as the injection is in the region of several arteries, veins and nerves. The needle should not be too small (so as not to penetrate tiny structures), the surgeon should draw back on the syringe (to ensure not have pierced a vessel), the lidocaine should not contain epinephrine (which could cause vasospasm), and the pressure of the injection must always be controlled. Only a limited number of injections can be made as they would otherwise lead to muscle atrophy. Diagnosis can be confirmed by response to this treatment; pain and swelling are expected to disappear in 48–72 hours. Some patients experience recurrence of trochleitis.

Inflammatory arthritis can be disabling to the point where people with the diseases can lose their jobs, which can cause psychological distress. Because it is typically progressive, those who lose their jobs are unlikely to re-enter the workforce after leaving due to their diagnosis. Programs now aim to retain those with inflammatory arthritis by preventing work-related injuries and by making necessary accommodations in the workplace. A 2014 Cochrane review found low-quality evidence that work focused interventions, including counseling, education, advocacy, and occupational medicine consultations, were effective in retaining workers with inflammatory arthritis.

In 1989, diagnostic criteria was created for the diagnosing of Winchester syndrome. The typical diagnosis criteria begin with skeletal radiological test results and two of the defining symptoms, such as short stature, coarse facial features, hyperpigmentation, or excessive hair growth. The typical tests that are performed are x-ray and magnetic resonance imaging. It appears that Winchester syndrome is more common in women than men. Winchester syndrome is very rare. There have only been a few individuals worldwide who were reported to have this disorder.

There is no pharmacological treatment for Roussy–Lévy syndrome.

Treatment options focus on palliative care and corrective therapy. Patients tend to benefit greatly from physical therapy (especially water therapy as it does not place excessive pressure on the muscles), while moderate activity is often recommended to maintain movement, flexibility, muscle strength and endurance.

Patients with foot deformities may benefit from corrective surgery, which, however, is usually a last resort. Most such surgeries include straightening and pinning the toes, lowering the arch, and sometimes, fusing the ankle joint to provide stability. Recovering from these surgeries is oftentimes long and difficult. Proper foot care including custom-made shoes and leg braces may minimize discomfort and increase function.

While no medicines are reported to treat the disorder, patients are advised to avoid certain medications as they may aggravate the symptoms.

There is no known cure for Winchester syndrome; however, there are many therapies that can aid in the treatment of symptoms. Such treatments can include medications: anti-inflammatories, muscle relaxants, and antibiotics. Many individuals will require physical therapy to promote movement and use of the limbs affected by the syndrome. Genetic counseling is typically prescribed for families to help aid in the understanding of the disease. There are a few clinical trials available to participate in. The prognosis for patients diagnosed with Winchester syndrome is positive. It has been reported that several affected individuals have lived to middle age; however,the disease is progressive and mobility will become limited towards the end of life. Eventually, the contractures will remain even with medical intervention, such as surgery.

Diagnosis requires a neurological examination and neuroimaging can be helpful.

BVVL can be differentially diagnosed from similar conditions like Fazio-Londe syndrome and amyotrophic lateral sclerosis, in that those two conditions don't involve sensorineural hearing loss, while BVVL, Madras motor neuron disease, Nathalie syndrome, and Boltshauser syndrome do. Nathalie syndrome does not involve lower cranial nerve symptoms, so it can be excluded if those are present. If there is evidence of lower motor neuron involvement, Boltshauser syndrome can be excluded. Finally, if there is a family history of the condition, then BVVL is more likely than MMND, as MMND tends to be sporadic.

Genetic testing is able to identify genetic mutations underying BVVL.

The cause of trochleitis is often unknown (idiopathic trochleitis), but it has been known to occur in patients with rheumatological diseases such as systemic lupus erythematosus, rheumatoid arthritis, enteropathic arthropathy, and psoriasis. In his study, Tychsen and his group evaluated trochleitis patients with echography and CT scan to demonstrate swelling and inflammation. Imaging studies showed inflammation of superior oblique tendon/ trochlear pulley. It was unclear whether the inflammation involved the trochlea itself, or the tissues surrounding the trochlea.

If a contracture is less than 30 degrees, it may not interfere with normal functioning. The common treatment is splinting and occupational therapy. Surgery is the last option for most cases as the result may not be satisfactory.

For children younger than eight weeks of age (and possibly in utero), a tethered cord may be observed using ultrasonography. Ultrasonography may still be useful through age 5 in limited circumstances.

MRI imaging appears to be the gold standard for diagnosing a tethered cord.

A tethered cord is often diagnosed as a "low conus." The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus below the L1-2 disk space may indicate a tethered cord and termination below L3-4 is unmistakably tethered. "Cord tethering is often assumed when the conus is below the normal L2-3 level.

TCS, however, is a clinical diagnosis that should be based on "neurological and musculoskeletal signs and symptoms. Imaging features are in general obtained to support rather than make the diagnosis." Clinical evaluation may include a simple rectal examination and may also include invasive or non-invasive urological examination. "Bladder dysfunction occurs in ~40% of patients affected by tethered cord syndrome. ... [I]t may be the earliest sign of the syndrome."
