Abstract: | Patellar instability is a common clinical problem affecting a young, active population. A large number of procedures have
been described to treat patellar instability. We present the clinical results in a case series of 25 medial patellofemoral
ligament reconstructions in 21 patients with up to 30 months follow-up (mean: 7.3). Reconstruction was performed using either
the gracilis or semitendinosus tendon autograft. The Tegner activity score improved overall from 3 to 4.4 at follow-up and
the mean follow-up Kujala score was 87 (range: 55–100). No patella redislocations were observed. Five patients (20%) required
a manipulation under anaesthetic but subsequently regained a satisfactory range of motion. Medial patellofemoral reconstruction
with both gracilis and semitendinosus tendon graft using a longitudinal tunnel technique provided good post-operative stability
restoring the primary soft tissue restraint to pathological lateral patellar displacement with no complications of post-operative
patellar fracture. |
