[Effects of trabecular metal augments for the reconstruction of Paprosky type Ⅲ acetabulum bone defects].
Objective: To investigate the methods and short-time clinical results of reconstruction of Paprosky type Ⅲ acetabulum bone defects by using tantalum augments. Methods: A total of 17 patients (17 hips) with Paprosky type Ⅲ acetabulum bone defects, treated with tantalum augments in revision of total hip arthroplasty at Department of Orthopedics Surgery in General Hospital of Chinese People's Liberation Army were retrospectively analyzed from March 2014 to May 2016. There were 6 males and 11 females aged from 23 to 74 years with an average of (50.2±16.3) years. ⋯ All the tantalum augments and biological acetabulum cups were stable, there were no infection, dislocation and other complications. Conclusions: The use of tantalum augments could be considered as an effective management of Paprosky type Ⅲ defects providing good clinical and radiographic outcomes in the short term. The cup-on-cup technique which was used in reconstruction of severe superior-invagination acetabular bone defects and restoration relatively normal center of rotation had special application value.

[Influence of patellofemoral joint degeneration on outcome of medial unicompartmental knee arthroplasty].
Objective: To evaluate the influence of patellofemoral joint degeneration and pre-operative pain location on the outcome of medial Oxford unicompartmental knee arthroplasty (UKA). Methods: A total of 58 patients (58 knees) with medial Oxford UKA had been performed for medial osteoarthritis from March 2013 to July 2014 in Department of Orthopaedic Surgery at First Teaching Hospital of Xinjiang Medical University were retrospective reviewed. There were 24 males and 34 females, the age from 43 to 87 years with the mean age was 68.5 years. ⋯ According to Outerbridge scoring system, there were no statistically differences in patients in patellofemoral joint degeneration group and normal group. Conclusions: There is a good evidence that neither mild to moderate degree of patellofemoral joint degeneration nor pre-operative pain location will compromise the short-term outcome of medial Oxford UKA, and should not be considered as contraindications. The situation is less clear for lateral patellofemoral degeneration, and more cautious option is advised.
