To evaluate the radiologic and functional outcomes of medial open wedge high tibial osteotomy (HTO) combined with arthroscopic procedure in patients with medial osteoarthritis.
From June 1996 to March 2010, 26 patients (32 knees) who underwent medial open wedge osteotomy and arthroscopic operation for medial osteoarthritis were retrospectively reviewed. Measurements included hip-knee-ankle (HKA) angle, femorotibial angle, medial proximal tibial angle, posterior tibial slope angle, and Kellgren-Lawrence grade. Clinical evaluation was performed using Lysholm knee scoring scale and knee and function score of the American Knee Society.
Differences between the mean preoperative and postoperative measurements were significant in all angles including the HKA angle (-5.7° and +5.5°), femorotibial angle (-1.9° and +9.8°), and medial proximal tibial angle (82.9° and 90.5°) (p<0.05). Mean Lysholm knee scoring scale was 63.6 preoperatively and 88.7 at the last follow-up, mean Knee Society knee score was 61.2 and 86.6, and mean function score was 59.3 and 87.2, respectively. All differences were significant (p<0.05).
Medial open wedge HTO in combination with arthroscopic procedure is an effective treatment method for medial osteoarthritis to treat varus deformity and an intra-articular lesion.
评估内侧开放性楔形高位胫骨截骨术（HTO）联合关节镜手术治疗内侧骨关节炎患者的放射学和功能结果。
回顾性分析1996年6月至2010年3月期间接受内侧开放性楔形截骨术和关节镜手术治疗内侧骨关节炎的26例患者（32膝）。测量指标包括髋-膝-踝（HKA）角、股胫角、胫骨近端内侧角、胫骨后倾角和Kellgren-Lawrence分级。采用Lysholm膝关节评分量表以及美国膝关节协会的膝关节和功能评分进行临床评估。
术前和术后测量的所有角度差异均有统计学意义，包括HKA角（-5.7°和+5.5°）、股胫角（-1.9°和+9.8°）以及胫骨近端内侧角（82.9°和90.5°）（p<0.05）。术前Lysholm膝关节评分量表的平均分为63.6分，末次随访时为88.7分；美国膝关节协会膝关节评分的平均分分别为61.2分和86.6分，功能评分的平均分分别为59.3分和87.2分。所有差异均有统计学意义（p<0.05）。
内侧开放性楔形HTO联合关节镜手术是治疗内侧骨关节炎内翻畸形和关节内病变的有效治疗方法。
