Background:
The medial patellofemoral ligament (MPFL) is considered the primary restraint to lateral patellar translation. Many of the reconstruction techniques proposed recently for patellar instability require bony procedures and implant use on the patellar or femoral side. The aim of this study was to describe the short-term clinical outcomes of MPFL reconstruction using a partial-thickness quadriceps tendon graft.
Methods:
Seven patients (two men, five women; mean age 23.7±4.1 yr) with chronic patellar instability had MPFL reconstruction using a partial-thickness quadriceps tendon graft. Patients were clinically and radiographically evaluated, and a Tegner-Lysholm score obtained preoperatively and at 6 and 12 mo postoperatively.
Results:
The mean follow-up period was 18.8 mo (range, 12–30 mo). The mean Tegner-Lysholm score improved from 63±7.9 preoperatively to 89.2±6.1 postoperatively (at 12 mo). Apprehension test was negative in all patients. No redislocation, subluxation, or complications were reported during the follow-up period.
Conclusions:
MPFL reconstruction with a partial-thickness quadriceps tendon graft was effective and was associated with good short-term clinical outcomes without the need for patellar bone tunnels and without complications.
Level of Evidence:
Level IV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
