Proximal fibular osteotomy: Alternative approach with medial compartment osteoarthritis knee – Indian context
Abstract
Context: Osteoarthritis knee is a common degenerative disorder for which various treatment modalities are available. Our aim was to evaluate the functional outcome and effectiveness of proximal fibular osteotomy (PFO) in patients who are unwilling to undergo total knee arthroplasty or high tibial osteotomy (HTO). Aims: To evaluate functional outcome of medial compartment osteoarthritis managed with PFO, clinically as well as radiologically in Indian study settings. Settings and Design: Study was done at the Department of Joint Replacement and Orthopedics, Tata Main Hospital, Interventional prospective cohort study. Subjects and Methods: Consecutive samples fulfilling study criteria were evaluated preoperatively with visual analogue scale (VAS) and preoperative functional status was assessed. The functional outcome was measured by pre- and postoperative VAS, Tegner Lysholm Knee score; X rays were used to measure pre- and postoperative “Medial joint space” and “Femoro-tibial angle (FTA).” Statistical Analysis: All the data were tabulated, and then analyzed with appropriate statistical tools “MedCalc. Chi-square test, test of significance and student paired and unpaired T-test were used. Results: There was a significant improvement in VAS score, Tegner Lysholm score postoperatively as compared to the pre-perative scores. FTA and medial joint space were also increased postoperatively. Conclusions: PFO is a good surgical alternative for medial compartmental osteoarthritis of the knee with an excellent functional outcome. A simple surgical procedure, non-requirement of specialized instruments, and low cost of surgery are some of the advantages for patients who do not want to undergo HTO or total knee replacement (TKR).
