摘要:

背景:手术治疗习惯性髌骨脱位可通过平衡髌骨内外侧软组织,改善Q角,达到纠正髌骨脱位。
目的:探讨Q 角测量评估膝关节软组织平衡和骨性手术治疗习惯性髌骨脱位的疗效。
方法:治疗前常规测量18例习惯性髌骨脱位患者Q角,按Q角分为两组:<16°组,行膝关节外侧关节囊松解、内侧关节囊紧缩;>16°组,行膝关节外侧关节囊松解、内侧关节囊紧缩+髌韧带止点内移或膝关节外侧关节囊松解、内侧关节囊紧缩+髌韧带止点内移和股内外侧肌止点位移。
结果与结论:两组术后Q角明显低于术前,术后膝关节评分明显高于术前(P < 0.001),两组间比较差异无显著性意义(P > 0.05)。Q 角测量评估显示平衡膝关节软组织和骨性手术治疗习惯性髌骨脱位具有疗效明确,并发症少,功能恢复好的优点。

Abstract:

BACKGROUND: Surgical treatment of habitual dislocation of the patella can improve the Q angle to correct dislocation of the patella through the lateral patellar soft tissue balance.
OBJECTIVE: To evaluate the clinical effects of surgical treatment of the habitual dislocation of the patella based on knee soft tissue balance by Q angle measurement.
METHODS: Q angles in 18 cases of habitual dislocation of the patella before surgery were measured, according to which, 18 cases were divided into two groups: <16° group, treated by the knee joint capsule lateral release, medial joint capsule tightening; >16° group, treated by the knee joint capsule lateral release, medial joint capsule tightening, tibial tubercle transposition and/or the lateral and medial part of quadriceps displacement.
RESULTS AND CONCLUSION: Postoperative Q angle was significantly improved in the two groups as compared with that before operation as well as the score of Lysholm-Gillquist (P < 0.001). There was no significant difference between the two groups ( > 0.05). Results of Q angle measurement show that based on on knee soft tissue balance, these surgery treatments for of patella dislocation have fewer complications and benefits to the functional recovery of the knee joint.
