ABSTRACT
Introduction: Osteoarthritis of the knee is a common musculoskeletal diseases affecting a major population in India. It can impact the individual's functions and activities of daily living. Total knee arthroplasty may raise controversy when treating the younger, athletic patient with arthritis. Arthroscopic debridement, high tibial osteotomy, unicondylar knee arthroplasty, and total knee arthroplasty allow younger patients to maintain an active, healthy lifestyle but can take a longer time to rehabilitate. PFO could be used as an alternative procedure. The Proximal Fibular Osteotomy, which provides immediate short term relief in cases with medial compartment osteoarthritis. Resecting a segment of fibula, loosens the lateral side allowing the upper tibia to settle into a more favorable lateral alignment, shifting the mechanical axis towards neutral or valgus. Aims & objectives: Ÿ To assess the functional, clinical and radiological outcome of proximal fibular osteotomy in grade 2 and 3 OA of knee and followed up for 1 year. Ÿ The clinical and functional outcome is accessed by Knee Society Score and VAS observed pre-op , post-op ,3 months ,6 months and 12 months. Ÿ The improvement in radiology is accessed using change in the medial joint space improvements in CP angle, change in the ratio of medial joint space to lateral joint space observed pre-op and post-op Methodology: The patients selected had grade 2 and 3 Osteoarthritis of knee according to Kellgren Lawrence classification between the age groups 20yrs-80yrs and are admitted to RajaRajeswari Medical College and Hospital, Bangalore. The Sample Size is 30 and is calculated based on previous studies as well as approximate availability of number of cases in the above mentioned duration satisfying inclusion and exclusion criteria. Clinical, functional and radiological outcome were used, Results were calculated using Knee Society Scoring Scale score. This study Conclusion: suggested that Proximal Fibular Osteotomy is an alternative procedure that can be used to treat medial compartment knee Osteoarthritis, if the patients are selected carefully. Patients followed up for one year showed a significant improvement in radiological, clinical and functional outcomes and thereby is an effective method of treatment in younger patients with Grade 2 and Grade 3 Osteoarthritis with an average BMI of 26.2.
