We present clinical results in a case series of 44 patients with medial patellofemoral ligament (MPFL) reconstruction with 12 to 32 months' follow-up.
Reconstruction was performed via gracilis tendon autograft looped through 2 transverse 4.5-mm drill holes in the patella and fixed at the natural MPFL insertion site on the medial femoral condyle with an interference screw. At follow-up, Kujala scores, Knee Injury and Osteoarthritis Outcome Scores, objective knee function, complications, and reoperations were assessed.
Only 1 patella redislocation was observed. Subluxation occurred in 3 patients, whereas 4 patients had chronic pain at follow-up, all of whom had cartilage injury at surgery. The Kujala knee function score improved overall from 46 points (range, 12 to 67 points) to 84 points (range, 62 to 100 points) at follow-up.
MPFL reconstruction with double transverse patella drill holes and a gracilis tendon graft provides good postoperative patellar stability. Postoperative pain seems to be related to the degree of patellofemoral injury found at surgery.
Level IV, therapeutic case series.
我们展示了44例接受髌股内侧韧带(MPFL)重建患者的临床结果,随访时间为12至32个月。
通过自体股薄肌腱重建,将肌腱穿过髌骨上两个4.5毫米的横向钻孔,并使用挤压螺钉固定于股骨内侧髁的MPFL天然附着点。随访时,评估Kujala评分、膝关节损伤和骨关节炎疗效评分、客观膝关节功能、并发症及再次手术情况。
仅观察到1例髌骨再脱位。3例患者出现半脱位,4例患者在随访时有慢性疼痛,所有这些患者在手术时均有软骨损伤。随访时,Kujala膝关节功能评分总体从46分(范围12至67分)提高到84分(范围62至100分)。
采用双横向髌骨钻孔和股薄肌腱移植进行MPFL重建可提供良好的术后髌骨稳定性。术后疼痛似乎与手术时发现的髌股损伤程度有关。
