Objective:
To observe clinical effect and influencing factor of total knee arthroplasty (TKA) for the treatment of stiff knee.
Methods:
From January 2010 to October 2014, 20 patients(25 knees) with stiff knee were treated with TKA. Among them, including 2 males(3 knees) and 18 females(22 knees), aged from 55 to 78 years old with an average of(64.5± 4.9) years old, the courses of disease ranged from 5 to 21 years with an average 8.3 years. Preoperative and postoperative HSS (hospital for special surgery knee score) score, activity range and complications were observed and compared.
Results:
All patients were followed up from 12 to 69 months with an average of 35.3 months. Ten patients occurred complications after operation. HSS score was improved from 32.36±12.31 preoperatively to 80.70±18.52 postoperatively, and had statistical difference between two groups;7 knees obtained excellent results, 15 knees good and 3 knees moderate. Activity range was improved from(39.4±5.3)°preoperatively to (92.5±11.2)° at the latest follow up.
Conclusions:
Total knee arthroplasty for stiffness knees is feasible and could obtain satisfied activity range and function.
