Background:
The medial patellofemoral ligament (MPFL) reconstruction is commonly conducted using gracilis, semitendinosus, quadriceps or tensor fascia lata tendon autografts or allografts. This approach, however, can sometimes lead to complications or morbidity at the site from which the graft is harvested. This study reports the clinical outcomes of non-elite competitive athletes who undergone MPFL reconstruction using an ultrahigh-strength 2-mm-wide tape.
Patients And Methods:
This retrospective cohort study included 67 non-elite athletes with acute or recurrent lateral patellar instability who underwent surgical treatment between December 2015 and December 2020. Athletes who underwent tibial tubercle osteotomy due to severe patellofemoral arthritis or severe osteochondral damage (kissing lesions or >2.5cm2) (1), trochlear dysplasia (Dejour type D dysplasia) (5), open physis (19) and revison MPFL reconstruction (8), were excluded. The remaining 34 athletes were followed postoperatively for a minimum of 48 months.
Results:
During the follow-up period, there was only one case and which was revised by adding Fulkerson Osteotomy. Two patients had limited range of motion and joint mobilization was performed under general anesthesia at the end of the second month. The International Knee documentation Committee (IKDC), Kujala, and visual analog scale (VAS) scores showed improvement postoperatively (p < 0.001). Moreover, the mean improvements in IKDC (≈+41), Kujala (≈+33), and VAS (≈-3.8) scores exceeded the established minimal clinically important difference (MCID) thresholds, indicating that the outcomes were not only statistically significant but also clinically meaningful for patients. When comparing the pre- and postoperative radiological measurements, the mean tilt angle and mean congruence angle showed a significant decrease (p < 0.001) CONCLUSION: Suture tape may be a good alternative to autograft, as it does not cause donor site morbidity. However, its most important disadvantage is its higher cost.
