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.

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.

Trochlear dysplasia is one of the most consistent anatomic factors that can lead to recurrent patellar dislocations. Various trochleoplasty procedures have been described to treat patellar dislocations in high-grade dysplasia by creating a new congruent trochlea. ⋯ Sulcus-deepening trochleoplasty is a valid option for the primary surgical treatment of carefully selected patients with recurrent patellar dislocations with high-grade trochlear dysplasia type B and D. Concomitant etiological factors must be cautiously corrected in an associated procedure. Midterm follow-up showed satisfactory restoration of patellar stability and improvement of knee scores with no complication of subsequent arthritis.

Symptomatic medial collateral ligament (MCL) instability is rare, and it is frequently associated with multiligament injuries. Most clinical investigations have failed to clearly define the specific objective outcome measures assessing the stability of the MCL quantitatively before and after the reconstruction procedure. ⋯ In a small set of patients with multiligament-injured knees, valgus laxity can be effectively restored through surgical management with superficial MCL reconstruction, when the other associated ligament injuries are reconstructed as well. The subjective functional results were significantly improved postoperatively at short-term follow-up.

Randomized Controlled Trial
Optimal dose of intra-articular corticosteroids for adhesive capsulitis: a randomized, triple-blind, placebo-controlled trial.
Intra-articular corticosteroid injection is a commonly used therapy for adhesive capsulitis, but there are only few studies that compare the efficacy of corticosteroids according to different doses. ⋯ We assessed the efficacy of corticosteroid injections according to 2 different doses that are most widely used in intra-articular injections for adhesive capsulitis. This study shows that there were no significant differences between the high- and low-dose corticosteroid groups, indicating the preferred use of a low dose in the initial stage.
