Trochlear dysplasia is an important etiological factor for the development of patellofemoral instability. Because a dislocation of the patella as a result of trochlear dysplasia results in a traumatic disruption of the medial patellofemoral ligament (MPFL), a combined trochleoplasty and patellofemoral ligament reconstruction appears to be the most appropriate procedure to treat patients with severe trochlear dysplasia. ⋯ Combined anatomic reconstruction of the MPFL and trochleoplasty reliably improved the stability of the patellofemoral joint in patients with severe trochlear dysplasia and no or mild degenerative changes. In addition, the described procedure showed significant improvement of knee function and good patient satisfaction without any episode of redislocations of the patella.

The efficacy of arthroscopic debridement or lavage for knee osteoarthritis (OA) was cast into doubt after publication of several randomized controlled trials beginning in 2002. ⋯ Evidence of the lack of efficacy of arthroscopy for knee OA, along with changes in reimbursement, preceded a significant decline in the population-based rates of this procedure in both publicly and privately insured patients in Florida.
