Abstract: Background:The author found that arthroscopic debridment and lavage of knee joint together with simpler, safe, effective, affordable, easy to perform, surgical procedure called partial fibular osteotomy (PFO) as compared to high tibial osteotomy and total knee replacement could effectively relieve immediate as well as long term knee pain and also correct the varus deformity for patient with medial compartment knee osteoarthritis kellgren and Lawrence grade I to III.
Methods:40 patients with medial compartment knee osteoarthritis who presented between January 2018 to July 2019 were treated by proximal fibular osteotomy and arthroscopic debridement in author’s hospital, all were followed for 1.5 yrs.
Anteroposterior and lateral weight bearing radiographs, the femorotibial angle (FTA) and lateral joint space and America knee society score (KSS) and visual analog scale (VAS) of knee joint were evaluated preoperatively and at 3month, 6 month and at final follow up respectively.
Results:At final follow mean FTA and lateral knee joint space were (172+_1.8) and (2.18+_0.8), which were significantly smaller than those measured preoperatively (184.27+_2.4) and (5.22+_1.2) respectively; both p< 0.05 Mean KSS at final follow up was (74.66+_12.54), significantly higher than preoperative score of (55.6+_11.54) p< 0.05, mean VAS score at final follow up (2.33+_0.98) significantly lower than preoperative VAS (6.66+_1.24).
Conclusion:The author found that proximal fibular osteotomy with arthroscopic knee joint lavage and debridement is a simple, safe, effective, easy to perform, gives excellent pain relief and can significantly improve both the radiographic apppereance and function of affected knee joint.
This procedure can be alternative treatment option for medial compartment knee osteoarthritis kellgen and Lawrence grade I to III especially in countries with limited health care delivery.
