EXAMINATION/TESTING

DROP JUMP TEST: This test is historically used to test for hip stability as a risk factor for ACL injury. It can equally be used for assessing hip stability as a factor in other lower limb conditions, including RPD.

SINGLE LEG DROP JUMP TEST: This test is a progression from the double leg drop jump test above, which allows you to test for functional symmetry of one leg compared to the other. The linked video doesn’t detail how to assess the movement, but it’s similar to what you look for with a double leg drop jump test (knee valgus, etc.). You will collect more accurate data if you have access to force plates (eg AxIT or Vald), and can video the test. NOTE: with this and all the subsequent single leg tests, there should be no more than a 10% difference in the measured outcome. If there is, return-to-play may not be indicated.

HOP TEST CLUSTER: These tests are most commonly used to test for lower limb functional symmetry. They are traditionally utilised in rehab from ACL injury, however are also useful in treating RPD and other knee conditions.

TRIPLE HOP TEST: Another good stability and power exercise, comparing one leg to the other.

TRIPLE HOP CROSSOVER TEST: This test is more challenging regarding stability and control. You may choose to use it near the end of your rehab process as a part of your return-to-play testing.

Y BALANCE TEST: This procedure will test balance, proprioception and strength on each leg, allowing you to compare the injured to the uninjured side. Normative data is easily found online.

TREATMENT

RPD can often require both surgery and rehabilitation to reduce the risk of subsequent dislocation. This table provides some indication of the risks associated with certain factors, as an aid to determining the need for surgery. Note: gender does not appear to be a factor.
