General, 21-Day Postoperative Rehabilitation Program Has Beneficial Effect on Oxidative Stress Markers in Patients after Total Hip or Knee Replacement

Table 4

Comparison of oxidative stress markers measured in the serum of patients () with hip or knee endoprosthesis before and after a 21-day general rehabilitation program. Statistical significance was set at .
