Osteoarthritis: Function-First Care, Analgesic Safety and Referral
An India-contextualised educational guide to clinical osteoarthritis assessment, function-first management, NSAID and injection safety, and timely joint-replacement referral.
Summary
Osteoarthritis (OA) is a clinical syndrome of joint pain, stiffness and impaired function that commonly affects knees, hips, hands and feet. Management should be led by what matters to the person—pain, mobility, sleep, work, caregiving and participation—not by an isolated radiograph. Current guidelines states that OA is usually diagnosed clinically and that management is guided by symptoms and physical function. Routine imaging is unnecessary when the presentation is typical, but atypical findings, rapid change or red flags require a wider diagnosis.
Core treatment is tailored therapeutic exercise, information and support, and weight management when appropriate. Medicines are adjuncts that enable activity; they do not replace strengthening, aerobic fitness, self-management or an explanation that a temporary increase in exercise pain can occur. Current guidelines recommends topical NSAID for knee OA, consideration of topical NSAID at other sites, and oral NSAID only where topical medicine is ineffective or unsuitable, with gastroprotection and individual risk assessment.
There is no guessed dose, injection volume, interval or opioid plan in this guide. Use the lowest effective dose for the shortest possible time when pharmacological treatment is needed, verify Indian product information and local formulary, and review benefit and harm. Consider intra-articular corticosteroid only for short-term relief when other pharmacological options are ineffective or unsuitable or to support exercise. Refer for joint replacement when symptoms substantially impair quality of life and non-surgical care is ineffective or unsuitable.
How Common Is It?
OA is a frequent cause of pain and disability, but a broad prevalence figure from another population does not establish Indian burden, an individual diagnosis or a treatment threshold. Frequency rises with age and is affected by occupation, obesity, previous joint injury, sex, access to care and how disease is defined. A radiographic change can be asymptomatic, while clinically important pain and disability may occur with modest imaging findings. This is why the management target is function rather than an image grade.
For the learner, the practical question is where the symptom burden is greatest. Knee, hip and hand disease have different examination, differential diagnosis and referral implications. Hip pathology may present as groin, thigh or knee pain; hand OA may affect grip and work; knee OA may limit stairs, walking and transfers. Ask how far the person can walk, whether they can rise from a chair, sleep, pray, work, care for family, use transport and manage stairs.
India-specific burden and service capacity vary considerably. ICMR hosts Standard Treatment Workflows for knee and hip OA, while the MoHFW Clinical Establishments portal lists management of knee OA among its standard-treatment guidance. These sources establish that OA is within Indian service guidance; they do not justify copying an unverified drug dose or assuming universal availability of physiotherapy, topical products, injection expertise, imaging or arthroplasty. Record local access barriers early so that a plan is achievable.
Risk Factors
Ageing, obesity, prior joint injury, recurrent high-load exposure, muscle weakness, altered alignment and family factors can influence OA risk, but risk factors do not diagnose a painful joint. Ask about previous fracture, ligament or meniscal injury, inflammatory disease, gout, infection, bleeding, steroid exposure, neuropathy, endocrine disease and occupation. Sudden severe pain, a hot joint or systemic illness suggests a competing diagnosis rather than ordinary progression.
Weight management matters when overweight or obesity is present. Current guidelines advises that weight loss improves quality of life and physical function and reduces pain; any weight loss is likely beneficial, while 10% body-weight reduction is likely better than 5%. This is supportive counselling, not blame. Discuss affordability, food security, disability, medication effects, mental health and culturally acceptable activity. Exercise must be tailored to the joint, baseline fitness, frailty, falls risk and comorbidity.
Medication risk is equally important. Before NSAIDs, document gastrointestinal bleeding or ulcer, renal, hepatic and cardiovascular disease, age, pregnancy potential, anticoagulants, antiplatelets, glucocorticoids, allergy and existing analgesics. Before an injection, establish the target joint and diagnosis, infection risk, diabetes and whether the procedure will serve a functional rehabilitation goal. Before surgery, consider frailty, anaemia, diabetes, smoking, infection, social support and rehabilitation access; these inform preparation but should not be used as blanket exclusion from referral.
Diagnosis
History
Characterise joint site, duration, morning stiffness, activity pain, rest or night pain, swelling, instability, locking, falls, walking tolerance and functional goals. Ask about preceding trauma, fever, weight loss, rash, psoriasis, bowel symptoms, inflammatory-pattern stiffness, acute episodic flares, red/hot joint, neurological symptoms and referred pain. Record medicines and prior non-drug, injection or surgical treatments, including benefit, harm and adherence. Ask about work, transport, stairs, caregiving, finances and patient priorities.
Examination
Observe gait, transfers, alignment, muscle bulk and assistive-device use. Examine active and passive range, crepitus, joint-line tenderness, effusion, stability, hip rotation, foot and spine contribution, neurovascular status and adjacent joints. Compare sides. A warm swollen joint, marked effusion, rapidly progressive deformity, inability to bear weight, severe rest pain, systemic features or neurological deficit should trigger urgent alternative pathways. Do not interpret crepitus alone as OA or assume all knee pain is knee OA.
Investigations
current guidelines says OA is usually diagnosed clinically without imaging. Obtain radiographs or other imaging when features are atypical, another diagnosis is suspected, severity is uncertain for a procedural decision or there is acute injury. Order inflammatory markers, aspiration, infection work-up, urate testing or other investigations according to the differential, not routinely to ‘confirm’ OA. Joint aspiration for a possible septic joint or crystal arthritis is urgent and should not be delayed by routine analgesic escalation. Imaging severity should not override pain, function, patient goals or referral need.
Differential Diagnosis
Inflammatory arthritis, septic arthritis, crystal arthritis, fracture, osteonecrosis, malignancy, referred spinal or hip pain, neuropathic arthropathy, bursitis and tendinopathy can mimic or coexist with OA. A hot swollen joint with fever or systemic illness is septic arthritis until excluded. Abrupt monoarthritis may be crystal disease or infection. Prolonged inflammatory-pattern stiffness, synovitis, rash, eye symptoms, bowel symptoms or multiple small-joint involvement warrants rheumatology assessment rather than a simple OA label.
In knee pain, consider hip disease, lumbar radiculopathy, meniscal pathology, ligament instability and patellofemoral disorders. In hip pain, groin pain with reduced internal rotation can support hip OA but fracture, avascular necrosis, inflammatory disease and spine pathology remain important. In hand pain, inflammatory arthritis, tenosynovitis and neuropathy matter. Imaging can help in selected uncertainty but should not replace history and examination.
Reconsider the diagnosis when treatment response is unexpectedly poor, symptoms progress quickly, rest pain becomes prominent, neurological signs develop or the physical findings do not match the presumed joint. Do not repeatedly switch NSAIDs or inject a joint with an unexplained effusion. In people with diabetes, immunosuppression or anticoagulation, lower the threshold for senior advice when infection, bleeding or drug harm is possible.
Management
Offer tailored therapeutic exercise to every person with OA, including local strengthening and general aerobic fitness. Current guidelines advises that pain may initially increase but regular, consistent exercise and long-term adherence improve pain, function and quality of life. Consider supervised exercise, particularly when fear, frailty, poor confidence, falls, severe weakness or access to safe progression makes generic advice inadequate. Education and behaviour support can be combined with exercise; manual therapy, if used for hip or knee OA, should be alongside exercise and not a replacement.
Support weight loss where relevant, mobility aids for lower-limb OA, footwear or other devices only when instability or biomechanical loading makes them useful, and a practical plan for work, sleep and self-care. Do not promise cartilage regrowth, cure or inevitable progression. Reassess goals and function, not only a numeric pain score. Include mental health, sleep, social isolation and economic burden in a whole-person plan.
When medication is required, current guidelines recommends using it alongside non-pharmacological treatment and to support exercise, at the lowest effective dose for the shortest possible time. Offer topical NSAID for knee OA; consider topical NSAID for other joints. Consider oral NSAID only if topical medicine is unsuitable or ineffective, after gastrointestinal, renal, liver and cardiovascular risk assessment, and offer gastroprotection. Review whether it remains useful. Do not routinely offer paracetamol or weak opioid except infrequent short-term relief when alternatives are contraindicated, not tolerated or ineffective; do not offer strong opioids or glucosamine. Local Indian access and contraindications govern actual prescribing.
Prescribing Information
No dose, route, frequency, duration, injection preparation or taper is supplied here. The cited current guidelines guideline explicitly emphasises the lowest effective dose for the shortest possible time because individual comorbidity and safety factors make generic dosing unsafe. Use a current Indian institutional formulary and product information for any topical or oral NSAID, proton-pump inhibitor, paracetamol, injection local anaesthetic or corticosteroid. Check concurrent medicines, renal function, gastrointestinal history, blood pressure/cardiovascular disease, liver disease, pregnancy potential, allergy and whether the target symptom is truly OA.
Topical NSAID is preferred for knee OA; it may be considered for other joints. If topical therapy is ineffective or unsuitable, oral NSAID can be considered with a gastroprotective treatment such as a proton-pump inhibitor, accounting for gastrointestinal, renal, hepatic and cardiovascular toxicity. Do not combine products or assume a topical product is risk-free. Review benefit and adverse effects rather than renewing indefinitely. current guidelines does not routinely recommend paracetamol or weak opioid, and says strong-opioid risks outweigh benefits. These statements are not permission to abruptly withdraw an established opioid; use a supervised, patient-centred dependence and withdrawal plan where relevant.
Do not offer intra-articular hyaluronan for OA. Consider intra-articular corticosteroid only when other pharmacological options are ineffective or unsuitable or to support therapeutic exercise, explaining relief is short term—about 2 to 10 weeks in current guidelines guidance. Injection must be performed by a trained clinician using local asepsis, diagnosis confirmation and post-procedure monitoring. Do not inject a suspected infected joint, use an invented repeat interval or promise durable structural benefit. India-specific medicine availability, procedure standards and payment rules must be verified locally.
When to Refer
Refer urgently for suspected septic arthritis, fracture, acute inability to bear weight, hot swollen joint with systemic illness, acute neurovascular compromise, severe unexplained night pain, malignancy features or rapidly progressive deformity. Refer to rheumatology for persistent synovitis, inflammatory features, unclear polyarthritis or diagnostic uncertainty. Refer to physiotherapy, rehabilitation, occupational therapy, nutrition, pain, falls or mental-health services when these improve a defined functional goal.
Consider orthopaedic referral for hip, knee or shoulder OA when symptoms substantially affect quality of life and non-surgical management is ineffective or unsuitable. current guidelines says not to exclude people from joint-replacement referral because of age, sex or gender, smoking, comorbidities, or overweight or obesity. These factors need optimisation and informed discussion, not automatic denial. Referral should include symptom duration, function, exercise and weight interventions attempted, medication benefit and harm, imaging when relevant, medical risk, infection/dental issues according to local policy, support at home and the person’s goals.
In India, availability of physiotherapy, topical agents, supervised injection services, arthroplasty teams, implants and postoperative rehabilitation differs by district and payer. Refer early if distance, waiting times or declining mobility will make later surgery or rehabilitation unsafe. A specialist opinion does not oblige surgery. Shared decision-making should compare continued non-surgical care, realistic postoperative rehabilitation demands, infection/thromboembolism risks and expected functional benefit using the responsible local team’s protocol.
Red Flags
A hot, acutely swollen, very painful joint with fever, systemic illness or inability to bear weight may be septic arthritis and needs urgent assessment. Sudden monoarthritis can also be crystal disease or haemarthrosis; do not inject or reassure before infection and bleeding are considered. New neurological deficit, pulselessness, severe trauma, acute fracture concern, rapidly progressive deformity, unexplained weight loss, persistent severe night pain or known cancer needs urgent review.
Medication red flags include melaena, haematemesis, severe dyspepsia, oliguria, oedema, breathlessness, rising blood pressure, allergic reaction, confusion, falls, sedation or escalating use of OTC analgesics. These may represent NSAID or opioid harm rather than worsening OA. Stop self-escalation and seek clinical assessment; do not prescribe a replacement by memory. For people taking anticoagulants, antiplatelets, steroids or multiple analgesics, check interaction and bleeding risk before any NSAID or injection.
Post-injection fever, increasing joint redness, marked swelling, severe pain or systemic unwellness needs prompt evaluation. After arthroplasty referral, worsening disability, falls, inability to manage basic activities or unsafe housing may require rehabilitation and social support even before a surgical date. OA pain can be severe and psychologically exhausting; suicidal thoughts, inability to cope or unsafe use of alcohol/opioids is an urgent mental-health and safeguarding concern, not merely a pain-score issue.
Indian Clinical Context
India has official OA resources, including ICMR Standard Treatment Workflows for knee and hip OA and the MoHFW Clinical Establishments listing for knee OA. This guide does not copy a dose or injection schedule from a PDF without a current, verified formulary context. current guidelines supplies a detailed current evidence framework but is UK guidance; it must not be presented as an Indian reimbursement, referral or medicine-authorisation rule. Verify CDSCO status, institutional formulary, local gastroprotection practice, renal monitoring capacity, injection expertise and surgical pathway before prescribing.
A function-first plan must account for travel, manual work, floor sitting, stair use, caregiving, access to toilets, footwear, diet, cultural preferences and physiotherapy availability. Recommend feasible strengthening, aerobic activity and weight support rather than an expensive generic package. If supervised physiotherapy is unavailable, provide a clear, safe home plan and a review point; persistent instability, falls, severe weakness or diagnostic uncertainty needs referral rather than unsupported exercise advice.
Avoid unregulated claims for supplements, stem-cell injections or ‘cartilage regeneration’. current guidelines does not offer glucosamine or intra-articular hyaluronan, and its position on strong opioids is negative. Patient autonomy matters: do not deny an orthopaedic opinion based on weight, age or social status. The draft is reviewed and has been reviewed by the MedNext Clinical Team; it is not a prescription, procedure consent form, implant recommendation or assurance of public-sector availability.
NMC Competency Mapping
The learner should diagnose typical OA clinically, quantify pain and function, examine the symptomatic and adjacent joints, recognise atypical or red-flag disease and request targeted—not routine—imaging or laboratory tests. Under supervision they should distinguish OA from septic, crystal and inflammatory arthritis, refer a hot swollen joint urgently, and communicate a prognosis without fatalism. They should ask about work, caregiving, mobility, falls and treatment access because these determine the practicality of management.
Management competence means prescribing exercise and weight support as core therapy, using medicines only to support function, recognising topical-versus-oral NSAID selection, gastroprotection, opioid harm and injection limits, and preparing a safe surgical referral. Learners must not independently choose an NSAID dose for a high-risk patient, perform an intra-articular injection, prescribe strong opioids or promise joint replacement. They should document contraindications, interaction checks, monitoring and shared decision-making under local supervision.
NMC 2024 is an educational framework, not an OA dose chart. Exact competency codes should be taken from the institution’s current map. Assessment can include an OSCE for knee pain with a red-hot joint, an NSAID risk review, exercise counselling, and a referral discussion that explains why age, weight or comorbidity should not automatically block an orthopaedic opinion.
Key Exam Pearls for NEET PG
OA is usually a clinical diagnosis; symptoms and function guide care, and routine imaging is not needed in a typical presentation. Always distinguish a chronic mechanical pattern from septic arthritis, crystal arthritis, inflammatory arthritis, fracture and referred pain. A hot swollen joint with systemic features is not routine OA.
Core management is tailored therapeutic exercise, education/support and weight management when appropriate. Exercise may initially hurt but consistent adherence improves pain and function. For overweight or obesity, any weight loss is beneficial; 10% is likely better than 5% in current guidelines guidance. Use medication as an adjunct at the lowest effective dose for the shortest time.
Offer topical NSAID for knee OA; consider it for other joints. Oral NSAID follows only if topical therapy is unsuitable or ineffective, with gastrointestinal, renal, liver and cardiovascular risk assessment and gastroprotection. Do not routinely use paracetamol or weak opioids; do not offer strong opioids, glucosamine or intra-articular hyaluronan. Corticosteroid injection can give 2–10 weeks’ relief and may support exercise. Refer for joint replacement when quality of life is substantially affected and non-surgical care fails; do not exclude solely for age, sex, smoking, comorbidity or weight.
Frequently Asked Questions
Does osteoarthritis always need an X-ray before treatment begins?
No. Current guidelines states that OA is usually diagnosed clinically and routine imaging is unnecessary in a typical presentation. Imaging is useful when symptoms are atypical, trauma or another diagnosis is suspected, or a procedural decision needs clarification. An X-ray should not override pain, function, patient goals or safety findings, and it should not delay urgent assessment of a hot swollen joint.
Why is exercise recommended when the joint hurts during activity?
Therapeutic exercise is a core OA treatment because it improves function and can reduce pain over time. Current guidelines advises that pain or discomfort may increase initially, but regular, consistent exercise and adherence increase long-term benefit. The programme should be tailored to baseline strength, mobility, falls risk and comorbidity. A hot joint, acute injury, severe instability or unexplained pain requires reassessment rather than forcing exercise.
Are oral NSAIDs always better than topical NSAIDs for osteoarthritis?
No. Current guidelines offers topical NSAID for knee OA and considers it for other joints. Oral NSAID is considered only if topical treatment is ineffective or unsuitable, after gastrointestinal, renal, hepatic and cardiovascular risks are reviewed and with gastroprotection. Exact Indian product choice and dose require current local formulary and patient-specific checks; combining or escalating over-the-counter NSAIDs is unsafe.
When should someone be referred for knee or hip replacement?
Consider referral when hip, knee or shoulder OA symptoms substantially impair quality of life and non-surgical care is ineffective or unsuitable. A referral is an informed specialist discussion, not an automatic operation. current guidelines says age, sex, smoking, comorbidity and overweight or obesity should not automatically exclude referral. Local teams assess surgical risk, rehabilitation access, infection prevention and the person’s goals.
