Joint Disorders Degenerative joint disorders — OA Noninfectious inflammatory disorders-RA etc. Systemic and local metabolic disorders-Gout, AVN etc. Trauma and sequels Congenital and developmental disorders Infection and sequels Neoplasm Miscellaneous
Surgery of the Joint Extra-articular Intra-articular Combined Mini-invasive Arthroscope aided Computer aided
Osteotomy To change the load of the joint
High tibial osteotomy For OA, varus deformity of the knee
Valgus osteotomy of the proximal femur Nonunion of the femoral neck fracture
Supracodylar osteotomy of the femur For valgus deformity of the knee
Innominate bone osteotomy For dysplasia of the hip
Realignment of the soft tissue To change the track of the joint during motion
Habitual dislocation of the patella Proximal and distal realignment
Synovectomy and/or debridement To remove the diseased synovium and/or diseased tissue from the joint Rheumatoid arthritis Pigmented villonodular synovitis etc.
Resectional arthroplasty To remove the diseased joint surface Ulnar head Metatarsal heads Metacarpal heads Radial head
Interpositional arthroplasty To reconstruct the joint surface with either soft tissue membrane or artificial spacer Soft tissue interposition of the elbow Silastic rubber interposition of the MP joint in hand with RA
Artificial joint arthroplasty Hemiarthroplasty Partial arthroplasty Total joint arthroplasty
Hemiarthroplasty Hip Femoral head prosthesis Bipolar prosthesis Shoulder Humeral head prosthesis

Arthrodesis To create solid fusion of the joint to prevent its motion For active infection, salvage of failed total joint arthroplasty, severe neuromascular disorders, severe trauma and some tumors Functional position
Arthrodesis of the hip
Arthrodesis of the knee
Arthrodesis of the ankle
Arthrodesis of the wrist
