Does TKA improve functional outcome and range of motion in patients with stiff knees?
The main goals of TKA are pain relief and improvement of function and range of motion (ROM). To ascertain whether TKA in patients with stiff knees would relieve pain and improve functional outcome and ROM, we asked four questions: whether (1) Knee Society and WOMAC scores would improve after TKA; (2) poor preoperative ROM would improve after TKA; (3) the revision rate of TKA in stiff knees would be high; and (4) complication rates would be high in these patients after TKA. We retrospectively reviewed 74 patients (86 knees) with stiff knees (mean age, 56.8 years) who underwent TKAs with a condylar constrained or a posterior stabilized prosthesis. The minimum followup was 5 years (mean, 9.1 years; range, 5-12 years). The mean preoperative Hospital for Special Surgery knee score and Knee Society knee and functional scores were 42, 11, and 42 points, respectively, and postoperatively they were 84, 90, and 84 points, respectively. Preoperative and postoperative total WOMAC scores were 73 and 34 points, respectively. One knee (1.2%) had aseptic loosening of the tibial component and 12 knees (14%) had complications. Despite a relatively high rate of complications, most patients had substantial improvement in function. ⋯ Level III, therapeutic study.

Review Case ReportsCase report: reconstruction of a recalcitrant scapular neck nonunion and literature review.
We present the first reported treatment failure of a reconstructed scapula body that proceeded to nonunion. This is a unique case report of an otherwise healthy patient who underwent open reduction and internal fixation of a scapula fracture nonunion, which is very rare. ⋯ Of 159 reported cases of open reduction and internal fixation for treatment of scapula neck and body fractures (with or without intraarticular glenoid fractures), there is not one reported case of a nonunion. Our case is described in detail, including the method of surgical reconstruction, and a review of the literature regarding surgical treatment of scapula nonunions after nonoperative treatment also is presented.
