Playing golf after THR and TKR is discussed controversially by orthopedic surgeons and Data of 16 patients receiving 22 THR (18 m/4f, 12 r/10 l) and of 11 patients receiving 12 TKR (9 m/3f, 6 r/6 l) were analysed using a questionnaire. The mean age of THR-/TKR-sportsmen was 65,7 (58 - 78)/67,8 (61-76) years. In THR-/TKR-patients surgery was done 59 (12-226)/39 (12-105) month ago. The best handicap (hcp) in their carrier/one year before/one year after surgery was in THR 15,7 (2-36)/18,5 (6-36)/17,7 (4-36), in TKR 18,4 (6-24)/22,1 (8-34)/20,3 (8-28). 11/7 sportsmen with THR/TKR could preserve the level of hcp following surgery, in 7/0 hcp became worse and in 4/5 hcp was even better. Patients with 21 THR and 12 TKR had less pain while playing golf in the operated joint one year after compared to one year before surgery, 1 patient with THR suffered more pain. During follow-up 13 THR/10 TKR reported of no problems playing golf, 7 THR/2 TKR had moderate pain, 2 THR/0 TKR had severe pain, no patients was unable playing golf following the joint replacement. Golf can be recommended as sporting activity after successful THR and TKR.
