A composite graft made of medial retinaculum and quadriceps tendon can be used instead of hamstring graft for medial patellofemoral reconstruction in recurrent dislocation of patella.
Jithin mohan et al conducted a unicentric, prospective observational study in 60 patients with recurrent dislocation of patella with normal Q angle and without trochlear dysplasia. A composite graft composed of medial patella retinaculum and quadriceps was harvested, one end was sutured at medial superior 2/3rd junction of patella with ethibond. The other end of graft fixed at schottles point with a bio screw. Patients were followed up at 6 weeks, 3 months, 6 months and then yearly. A preoperative and post operative Lysholm score and Kujala score were used for comparison.
The key findings of the study were:
• Most of the study population was between age group 21- 30 years (38.3%) youngest was 14 years of age and oldest with 45 years.
• The average age of study population was 26.83 +/- 9.127.
• 65% of the study population were female.
• There was a significant improvement in Kujala and Lysholm scores.
• Only 3 out of 60 patients developed further instability that was managed non surgically.
• There was no statistically significant association with ligamentous laxity and the outcome.
The authors concluded – “The functional outcome of novel technique of medial patellofemoral reconstruction is comparable with conventional techniques. It has added advantage of medial plication and VMO advancement. In our technique the subluxation rate is low, no incidence of patella fracture as it is an anchorless technique and no donor site morbidity. Since it does not require anchor on the patella it is cost effective also.”
