Impingement of infrapatellar fat pad (Hoffa's disease): results of high-portal arthroscopic resection.

Purpose: We performed a retrospective cohort study with prospective data collection to assess clinical and functional outcomes of painful impingement of the infrapatellar fat pad (Hoffa's disease) treated with high-portal arthroscopic resection.

Methods: Hoffa's disease as an isolated lesion was confirmed by arthroscopy in 34 patients with recalcitrant anterior knee pain. The visualization portals were made high in the soft spot above the level of the lower pole of the patella.

Is osteitis pubis associated with the use of bone anchors in urinary continence operations?

We studied 130 patients who underwent either a vaginal needle suspension procedure or a pubofascial sling procedure with Mitek titanium bone anchors to determine the association of osteitis pubis with bone anchoring in these procedures. Fifteen patients complained of postoperative suprapubic pain; five cases were due to wound infections and another five were associated with tying the suspension sutures too tightly. We suggest the use of the term 'periostitis pubis' to describe the remaining five patients who suffered suprapubic pain.

Gait adaptations in patients with chronic posterior instability of the knee.

Objective: A retrospective analysis was performed to assess gait in individuals with a long history of posterior knee instability.

Design: Descriptive study.

Background: There are few studies in the literature concerning evaluation of the biomechanics of the knee in patients with knee posterior instability.

Osteoid osteoma of the pisiform.

Osteoid osteoma of the pisiform seems not to have been previously reported. In both the cases reported in this paper there was diagnostic difficulty and delay. Complete surgical removal of the nidus was curative.
