Symptoms & signs which are associated with defective integrity of articular cartilage, in addition to related changes in the underlying bone at the joint margins. American College of Rheumatology- 2005
Also known as degenerative joint disease, is the most common form of arthritis, and a leading cause of disability worldwide.
OA Knee is one of the five leading causes of physical disability in non- hospitalized elderly men & women. The risk for disability is as great as cardiovascular disease & greater than that due to any other medical condition in elderly.
7.35% of the total population are suffering from osteoarthritis. 7% population in Indian are above the age of 60 years. Out of that 20% are suffering from OA knee & needs some kind of treatment (Physical, medical, Surgical) But only a few get treatment (Surgeries/ joint replacement). Bangladesh data are not available.
Young patients age less than 55 presenting with uni-compartmental symptom. Older patient presenting with symptoms of bi-compartment with patello-femoral arthritis. Patient with inflammatory arthritis- any age group.
Osteoarthritis of the knee increase in prevalence with age & is more common in women than in men.
OA affects all structures within joint. Loss of hyaline articular cartilage. Synovial inflammation. Capsular stretching and weakness of periarticular muscles. Mal-alignmentTibia vara/Genu Varum Genu valgum or knock knee (Lateral compartment arthritis)
Osteitis, synovial inflammation & a stretched joint capsule filled with fluid are to be sources of pain. Bursitis may add. Hyaline Articular cartilage is destroyed & sub-chondral bone is exposed leads to painful knee.
Age & sex Obesity Previous existing deformity Knee injury Repetitive Stress injuries High impact sports Repetitive episodes of TB/gout/septic arthritis hemophilic arthritis/Psoriatic arthritis/ neuropathic arthritis
Gradual destruction of Articular cartilage Mild thickening of synovium & inflammation Thickening of joint capsule.
Gradual destruction of hyaline cartilage
Complete loss of medial joint cartilage with osteophytes formation
Cell stress
Cytokine IL-1, IL-6, TNF-
Cartilage destruction
Synovial destruction
OA.
Sub-chondral bone destruction
Clinical diagnosis Laboratory diagnosis Radiological diagnosis
Pain – Bone angina Restricted joint movement- stiffness Swelling ] Mild joint instability Crepitus (on movement) Effusion Joint deformity & instability
General Examination - Vital Sign - obesity - Neurological status - DM - HTN
Local Examination - Site of pain, tenderness, crepitus - Deformity Varus (OA) Valgus (RA) - Synovitis - Osteophytes - Instability - ROM
General Examination - Vital Sign - obesity - Neurological status - DM - HTN Local Examination - Site of pain, tenderness, crepitus - Deformity Varus (OA) Valgus (RA) - Synovitis - Osteophytes - Instability - ROM - Gait (Wadding/ Trendelenberg)
CBC - For infective/ inflammatory pathology ESR – Inflammatory condition CRP – For differentiate with infection RA Factor – RA. ANA titre – RA. Synovial Fluid examination – D/D Crystal examination – For gout / pseudo gout HLA – B27 – AS.
X- Ray – AP standing, Lateral, stress view sky-line view (Digital X-Ray are preferred)

Prevention Physical treatment Medical treatment Surgical treatment
Pain control Increase mobility Further degeneration prevention Enhance healing process Improve quality of life
Education about the problem & fate Habit change & life style modification - Avoidance of squatting, cross leg sitting Weight reduction Physiotherapy Control of DM. Endocrine disorders.
Physiotherapy - Quadriceps strengthening - Hamstring strengthening Local treatment - SWD - UST - knee cap. Load reduction over knee - Use of support – stick - Valgus brace - wedged insole - weight reduction - gait modification - out toeing - slow walking
Symptom modifying drugs - NSAIDs - Analgesics- tramadol, paracetamol - Safer drug – naproxen. Nutraceuticals - Glucosamine sulfate - chondroitin sulfate Disease modifying anti- OA drugsDiacerein Calcium supplement Muscle relaxant - ?? Visco supplementation
Arthroscopic
debridement HTO Unicondylar knee replacement. Total knee replacement
Joint space narrowing (Grade1)
Obliteration of joint space (Grade-2) HTO + Arthroscopy/UKA
For joint debridement & lavage Abrasion arthroplasty Degenerative meniscal tears Synovectomy in RA Chondrocyte implantation Post traumatic arthrofibrosis
Marrow stimulation techniques Abrasion chondroplasty Microfracture techniques (Steandman JR CORR) 2001; 391 (Suppl): S 362 – S 369
Cartilage restoration procedure - Osteo chondral auto – graft transfer (mosaic plasty) - Autogenous chondrocyte implantation (ACI) - Cartilage transplantation - Osteo chondral allograft trasplantation
Grde 1 – 2 of medial compartment arthritis Relatively young patient < 60 yrs No or minimal deformity Non inflammatory disease pathology.
Arthroplasty Unicondylar knee arthroplasty (UKA) Total knee arthroplasty (TKA)
Almost 70% of arthritic knee are confined to medial compartment (Till death) Replacing only the diseased or affected part of Tibio-Femoral joint - Available since 30 yrs - Popularized in last decade.
Symptomatic uni-compartmental arthritis Varus/ Valgus deformity less than 150 Flexion contracture less than 100 Passive ROM more than 800 Young active patients Intact PCLs
Bi-compartmental / tri-compartmental arthritis Rheumatoid arthritis PCL deficit More than 150 varus/valgus deformity More than 100 flexion contracture Stiff knee Obesity
Considered to be gold standard in treatment of advanced arthritis or inflammatory arthritis (RA)
For patient with advance disease, gross deformity, limited activity in life.
Young patient (age<55) - Cruciate retaining - Bone consenving design - cement less TKR Older patient (age> 55) - High flexion TKR - PS/CR
Current surgical trends
Minimally invasive surgery Use of navigation
OA is very common clinical condition seen in out patient department Conservative management includes drugs & physiotherapy should be first line of management In selected patient uni-condylar knee replacement gives good, long-lasting results.
Set up new isolated upgraded unit for proper clinical, laboratory & radiological examination OT set up with training manpower including OT nurse, stuffs & surgeons. Collaboration between neighboring country & exchange of views & good bilateral technical exchange. Good support & patronization by BOS & Government.
