Our results suggest that compared with CS , SS may provide superior bone remodelling and similar survival rates and clinical outcomes .
However , the short-term follow-up of the included studies was inadequate to determine the long-term performance of SS
OBJECTIVE Cementless total hip arthroplasty (  THA ) is associated with reliable clinical results and high patient satisfaction .
Short-stem prostheses ( SS ) were design ed to achieve superior preservation of proximal bone stock and stability compared with those of conventional-stem prostheses ( CS ) .
This meta- analysis was conducted to determine the proximal bone remodelling , revision rate , Harris Hip Score , radiolucent line and maximum total point motion values of both SS and CS for primary THA .
Second-generation Extensively Porous-coated THA Stems at Minimum 10-year Followup
The relatively high prevalence of thigh pain and stress shielding associated with the AML porous-coated cementless femoral component led to the development of the Prodigy ® , a femoral component with more extensive porous-coating and a distal polished bullet tip with medial diaphyseal relief to potentially decrease the flexural rigidity . We prospect ively evaluated a cohort of 100 consecutive cementless total hip arthroplasties performed using this device . The minimum followup was 10 years ( mean , 11.4 years ; range , 10–12 years ) . At 10-year followup , 69 of the 86 patients ( 82 hips ) were living , 14 patients with 15 hips were deceased , and three patients with three hips were lost to followup . No hips required a stem revision . Two patients ( two hips ) complained of thigh pain . All hips were bone ingrown . Distal tip radiolucencies and osteolysis occurred in 13 hips ( 17 % ) and none , respectively . Twenty-one hips ( 28 % ) demonstrated moderate or severe stress shielding . Only further followup will determine if this could be a clinical problem or one with revision surgery . These results encourage the authors to continue using second-generation extensively coated stems in their primary total hip arthroplasty constructs .
