“…One study describes a minimally invasive technique to reconstruct the MPFL using an artificial ligament and provides descriptive information about clinical benefits and safety in a broad population of patients with all grades of patellar instability 9 . Reports on FiberTape in MPFL reconstruction demonstrated that it is safe and effective and provides higher initial strength than the hamstring tendon 10, 11 . The major advantage of using synthetic materials for MPFL reconstruction is that the autologous tendon is retained and, thus, donor complications are reduced.…”

Objective To describe a surgical technique using suture tape for reconstruction of the medial patellofemoral ligament (MPFL). This technique restores the stability of the reconstructed ligament and has excellent postoperative outcomes. Method This is a retrospective analysis. From January 2016 to June 2018, 17 patients underwent MPFL reconstruction using high‐strength suture (FiberTape; Arthrex) augmentation, with at least 12 months of follow up. There were 11 female and 6 male patients. The mean age at the time of MPFL reconstruction was 22.1 years (range 13–34 years). Clinical outcomes included pain level, knee range of motion, passive patellar hypermobility, and maltracking at follow‐up. The lateral patellofemoral angles, congruence angles, and patellar tilt angles were measured in a skyline view by CT at 30° of knee flexion at 12 months. Functional outcomes were assessed using the Lysholm knee scoring scale, the SF‐12 score, the Tegner score, and the Crosby and Insall grading system at yearly follow‐up. Result No patients were lost at the last follow up. One patient had recurrence of patellar dislocation and none of the others had serious complications. The success rate of MPFL repair for preventing recurrent dislocations was 94.1% (16 of 17 knees). Fifteen knees had full range of motion of more than 130°. At follow‐up, 2 knees were judged to have mild hypermobility and none had severe hypermobility or maltracking. Using the Crosby and Insall grading system, 12 knees (70.6%) were graded as excellent, 4 knees (23.5%) as good, 1 knee (5.9%) as fair to poor, and none as worse at the last follow‐up assessment. In all patients, the Lysholm knee score (55.12 ± 13.52 vs 79.88 ± 7.50, P < 0.01), the SF‐12 score (47 ± 9.53 vs 65.24 ± 12.82, P < 0.01), and the Tegner score (2.76 ± 1.39 vs 6.53 ± 1.70, P < 0.01) had improved at their 12‐month follow up. Compared with preoperative radiological findings, there was a significant improvement in lateral patellofemoral angle (−10.24 ± 7.10 vs 6 ± 5.43, P < 0.01), patellar tilt angle (26.53 ± 7.23 vs 9.88 ± 4.24, P < 0.01), and congruence angle (29.59 ± 11.95 vs −8.65 ± 4.86, P < 0.01). Conclusion The use of FiberTape in MPFL reconstruction can improve the stability of the knee following surgery and has good midterm clinical results and low complication rates.

“…FiberTape fixed by SwiveLock anchors was stiffer than native MPFL. 7 Therefore, the suture tape should be fixed at >60° of knee flexion to avoid excessive PF joint contact pressure.…”

“…Since the SwiveLock anchor fixation system provides secure initial fixation, 7 patients are allowed full weight-bearing with crutches from the first day after surgery. Early range of motion and muscle control exercises, such as patellar setting and straight leg raising, are also started as soon as possible.…”

“…Recently, the use of polyester suture tape (FiberTape; Arthrex, North Naples, FL) with knotless anchors (SwiveLock; Arthrex) for MPFL reconstruction has been reported. 5 , 6 FiberTape with SwiveLock anchors has stronger ultimate load than a hamstring tendon with soft anchors 7 ; however, it stiffness is significantly different from that of autologous tissue. 7 This is both an advantage and a disadvantage in MPFL reconstruction.…”

One of the possible complications of synthetics is an overconstrained patellofemoral (PF) joint, which may result in prolonged postoperative rehabilitation, anterior knee pain, and degenerative change of the PF joint.…”

Medial patellofemoral ligament (MPFL) reconstruction usually involves hamstring autografts and is associated with donor-site morbidity. Excellent short-term results with MPFL reconstruction using synthetic materials have been reported. Although synthetics do not sacrifice autologous tissues, their material properties are significantly different from those of biological tissues. Therefore, accurate surgical procedures are required to achieve excellent results. The purpose of this report was to describe our surgical method for MPFL reconstruction using FiberTape and knotless SwiveLock anchors.
