Paper 10: Judo After Total Hip and Knee Arthroplasty



      Today there are more and more candidates for arthroplasty among people participating in a regular sport. These patients are demanding a high level of functional performance from their prosthesis.
      Many epidemiological studies have shown that regular participation in a sport after total hip and knee replacement is possible, particularly as far as golf, skiing and tennis are concerned.
      On the other hand no studies have yet been undertaken on judo.
      We wanted to know if continuing judo was compatible with a prosthesis.


      We sent a questionnaire to members of the French Judo Federation to identify sportsmen with total hip and knee replacements. We sent out 212 questionnaires to sportsmen of over 60 who were at least 6th Dan, black belt level. Out of 83 replies, 36 men of a mean 72 years old (60-86 years of age) had at least one prosthesis.


      We found 36 total hip replacements on 27 patients, 10 total knee replacements on 8 patients and 3 total shoulder replacements on 3 patients.
      Out of 27 patients with a total hip replacement, mean age 63 (60 to 82 years) at the time of the operation; Fifteen (55%) said they had been operated so as to continue judo. Twenty two patients (81%) had taken up judo again on a regular mean basis 2.5 times a week (1 to 4) a short time afterwards, 3.9 months (2 to 10). But they had all, apart from one, changed exercises (theme randori or demonstration).
      Finally, their surgeons had recommended that they give up judo in 65% of the cases.
      Twenty five patients (92%) declared they were satisfied with their prosthesis.
      Only 2 patients out of 26 with a hip replacement had had another total hip replacement because of wear. We found no dislocation or fracture.
      Among the 8 patients with a total knee replacement, mean age 72 years old (60 to 77) at the time of the operation; Four patients (50%) said they had had the operation to continue judo.
      Five patients (62%) had taken up judo again on a regular basis, 2.3 times a week (1 to 3) a short time after, 5.2 months (3 to 6). They had all changed exercises; (theme randori or demonstration). Their surgeons had recommended they give up judo in 75% of the cases.
      Only 5 patients (62%) were satisfied with their prosthesis.
      Among the three patients with a total shoulder replacement; Two had take up judo again;


      A total hip replacement does not appear to limit participation in judo. The functional results are satisfactory. A clinical and radiological study appears necessary to confirm these results. The results after total knee replacement are more reserved, it appears that continuing judo might present more difficulties for older sportsmen.
