Abstract:
OBJECTIVE:To evaluate the clinical efficacy of modified high tibial osteotomy combined with platelet-rich plasma in the treatment of moderate to severe knee osteoarthritis.
METHODS:From January 2021 to March 2022, the clinical data of 60 patients with moderate to severe knee osteoarthritis admitted to the Third Affiliated Hospital of Beijing University of Chinese Medicine were analyzed. Among them, 30 patients were treated with modified tibia high osteotomy combined with platelet-rich plasma as the observation group, including 12 males and 18 females, aged from 51 to 74 years old, with an average age of (64.37±5.72) years old. The course of disease ranged from 1 to 7 years with an average of(3.43±1.41) years. Thirty patients were treated with modified high tibial osteotomy combined with sodium hyaluronate as control group, including 10 males and 20 females, aged from 50 to 78 years, with an average age of (64.33±8.18) years. The course of disease was 1 to 7 years with an average of(3.30±1.39) years. Knee X-rays were taken before surgery and at the last follow-up, and the changes of lower limb bearing-line ratio (WBLR), proximal medial tibial Angle (MPTA), femoro-tibial angle (FTA) and posterior tibial slope (PTS) were compared between the two times. Visual analogue scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Lysholm score were used to evaluate knee pain and functional changes before surgery and at 1, 3, and 6 months after surgery.
RESULTS:The wounds of all patients healed in stage I after surgery. All 60 patients completed treatment and follow-up, with an average follow-up duration of (8.08±1.75) months, ranged from 6 to 12 months. No serious adverse events or complications occurred. At the last follow-up, WBLR, MPTA and FTA were significantly improved in both groups (P<0.05). At the last follow-up, there was no significant difference in PTS between the two groups compared with pre-operation(P>0.05). At the last follow-up, there were no significant differences in WBLR, MPTA, FTA and PTS between the observation group and the control group (P>0.05). The VAS scores, WOMAC scores and Lysholm scores of both groups were significantly Modified with time after operation (P<0.05). At 1, 3 and 6 months after operation, VAS score, WOMAC score and Lysholm score of the observation group were significantly better than those of the control group, with statistical significance (P<0.05).
CONCLUSION:For patients with moderate and severe knee osteoarthritis, modified high tibial osteotomy can significantly correct lower limb alignment, and combined with platelet-rich plasma therapy can further significantly relieve knee pain and improve knee function, the effect is better than combined with sodium hyaluronate.
