Early Clinical Efficacy Of Arthroscopic Debridement Unites Fibular Osteotomy For Knee Osteoarthritis

Objective To investigate the clinical efficacy of arthroscopic debridement unites fibular osteotomy for osteoarthritis of knee.Methods We retrospectively analyzed 49 patients (55 knees) from May 2015 to January 2016 in our hospital, with the diagnosis and treatment of knee osteoarthritis in patients with clinical data.23 patients (24 knees) underwent the arthroscopic debridement therapy (group A) and 26 patients (31 knees) underwent the arthroscopic debridement unites fibular osteotomy (group B). Every patient was graded according to the cartilage lesion under the arthropic visual observation. In group A, there are 10 cases,11cases and 3 cases belong to grade II, grade III and grade IV, respectively. Under the same conditions, there are 11 cases,13 cases and 7 cases in group B. VAS, Lysholm and HSS score, IL-6, TNF-a level in synovial fluid and complication rate were measured separately and comparsion was done between two groups.Results The mean follow-up in group A and group B was (7.17±2.89) months and (7.00±1.79) months, respectively. Compared to pre-operation, the postoperative VAS score and IL-6, TNF-α level were lower, postoperative Lysholm and HSS score were increased in both groups, the difference was statistically significant (p<0.05). The VAS score and IL-6, TNF-a levels in group B were lower than group A, the Lysholm score and HSS score in group B were greater than group A, the difference was statistically significant (p<0.05). The postoperative Lysholm and HSS score in both groups with the cartilage lesion grade II and III was increased compared to pre-operation, the difference was statistically significant (p<0.05). Then compare to the pre-operation, the difference of postoperative Lysholm and HSS score in both groups with cartilage lesion grade IVwas not statistically significant (p>0.05). No complication was found in group A, one patients (1 knee 3.2%) suffered neurological injury and one (1 knee 3.2%) had local wound infection in group B.Conclusion Arthroscopic debridement unites fibular osteotomy for knee osteoarthritis as a safe, effective and simple surgical procedure. Effective for the pain of knee, reduces the local inflammation and improves the post-operative function for the knee with cartilage lesion grade Ⅱ or Ⅲ.
