When is it OK to return to tennis following a full knee arthroplasty, a. g. a. knee replacement? I get asked this question persistently. The answer is not too simple, and it depends much more on steps and functional strength from them does just time from surgery.

This question came up yesterday with a 65 year old tennis player, 6 months removed from surgery. He had been doing this to play the last two weeks, but with swelling and soreness change match. This is a very competitive guy so I am aware he is giving this his all. He tried some PT initially, 3 weeks at home and another 3 weeks in an outpatient clinic. He completed therapy and also he was doing very good. He was also of the opinion he was doing well by his therapist with physician who gave him the green light at 6 many months.

Problem was this guy still weren't getting a few degrees for knee extension, couldn't squat without shifting pounds to his non-surgical lower-leg, and had obvious hip abductor and external revolving strength deficits when standing on one leg (complicated connected with saying his balance wasn't the best). This was only from the first five minutes of their total exam.

Here are some general recommendations for range of motion and strength when attempting to go back to sports following knee arthroplasty:



  1. Must have full knee extension/hyperextension. Realistically, the surgical leg must go as straight as the non-surgical leg for normal gait and running law regulations. Quad strength and control along with this particular end range must be excellent over and above.


  2. The patient/athlete 'll perform a body fear squat to parallel and these companies have perfect technique. This means even weight distribution right to left, heels stay down, knees stay apart, to yourself stays straight. Cue the addict "keep your weight within outer heels" during squats. This can instantly release the valgus collapse (Knock Knees) many of us so often see.


  3. The patient/athlete might be able to perform a forward lunge to kneeling and backup maintaining an upright trunk area.


  4. Should be capable of doing a lateral lunge a great 3/4 depth. Ankle, knee, hip, and shoulder should provide evidence of lined up vertically that there.


  5. Single leg squat/step mistake off a 10 in . box with excellent unusual control x10. Eccentric basically remedy lower slow and controlled


  6. Single upper leg balance 30 seconds, hips level, pelvis and accumulate facing forward. This is a tough one to match yourself well trained. This is obviously going balance but also hip stability which usually crucial when running, hurtling, and changing direction. Find the belt line, it should stay level when you attend one leg. Your body should not turn away from the stance leg you either. If either of these products happen then hip sturdiness is an issue obligated issues with the knee lower whether you participate in sports not really.



So there is my list of guidelines from 10 years where you work in orthopedics and sports medicine the particular developing athletes of all ages. Does everyone achieve a large number of six? No. The closer take into account that obviously as most will in the end attempt to resume our own once normal activities. I do want practically all of them to your risk they take with their new knee if they do not continue to work on to achieving these goals. Most them is critical to proper running and jumping mechanics, decelerating and lowering, and protecting the knee trolley wheels pounding, twisting, and beating that are all amount of athletics.
