90 degrees rule

Posted , 12 users are following.

Hi everyone, im 38 years old and I had a LTHR JUST OVER 3 weeks ago and I am now walking without crutches but with a bit of a limp, I have been advised about the 90 degree rule from my doctors but was hoping someone would be able to shed a bit more light on this for me? My questions are, how long do I have to adhere to this? If I bring my knee up over 90 degrees will this do any other damage or is it just risking dislocation? Hope this makes sense and look forward to hearing from you all

    Gerard, It’s still so early in your recovery that it’s not unusual to have a slight limp. My PT told me to do all my exercises to strengthen muscles again to avoid the limp. She would always observe my gait and comment and encourage me. You say “or is it just risk of dislocation?). Isn’t that enough of a risk for you ? That’s a huge risk you don’t want to take!  I had posterior THR and had the 90 degree restrictions for 6 weeks. Follow doctor’s advice and PT’s advice and I hope all will go well for you.

      Hi Margot, thank you for your reply and advice it's very much appreciated. Apologies if my dislocation comment sounded a bit flippant, I definitely think that is a massive risk but what I meant is that some times I have sat in a chair where my hip goes slightly out of the 90 degree angle then immediately correct it, but was concerned that I had done some other damage, for example to my recovery. Hope that makes sense.

      I see what you mean Gerard. I was completely paranoid about the 90 degree rule and was often unsure if I was obeying it properly or not, so I understand your questions.  I was constantly asking my PT about it !  Eventually, I suppose I developed a better sense of what it was as time went on. I followed the 90 degree rule way longer than I was told because I wasn't so confident. I have a feeling it would have to be more than a second or two to do any damage and you are clearly conscientious. My best wishes to you.

    A cane will take that limp from you - at least did me... I would have thot you’d need to be on it for some weeks yet - and my doc said no 90 degree angle for 12 weeks... didn’t want to take chance in dislocating...

    Hi I’m 3 months left THR my doctor said 90 degree rule for 6 wks or until your check up. Then he told me ease yourself back to bending,not to force it.i pretty much do all bending now. I had a limb and my surgeon said to lay on bed on unoperated leg with pillow between leg and lift operated leg up and hold 5 seconds,10 repetitions. As you get better hold 10 seconds. Do 3 times daily. Did wonders for my limp. I’m having my 3 month X-ray this week and a surgeon appointment in 2 weeks time,then we are pretty much done but for yearly appointments.

    Lots of times I forget i’ve had this surgery but during the 1st 2 months I thought this day would never come.

    Good Luck

      Hi Faye, thanks for your reply, great to hear you are doing so well, gives me some confidence knowing it does get better so thank you

      The exercise you have described to get rid of the limp, do you know if this can be done now or would i have to wait until 6 weeks after the surgery? Many thanks again

      We here in Nova Scotia receive a booklet and it states not until after 6 wks. I waited until my 6 wk check up and he said to go home and start the exercise right away.

    hi Gerard,

    You want to avoid limping. That will throw your body out of alignment and can impede recovery. A cane or trekking poles can help. My doctor was fine with whatever aids I preferred.

    My doctor has cautioned that I should be careful about the 90 degree rule for life! He did clarify (thankfully) that I can bend past that as I get stronger and regain mobility, but he said not to break the rule with PT or other stressful exercises. Fear that I’ll never be able to use my concept 2 rower again...

    I was given a set of exercises to start using as soon as I got home: marching in place, swinging each leg outwards (not crossing midline), etc. I did these 2-3 times a day along with walking (with aids). I imagine you can do a google search for “exercises after hip replacement”. My physical therapists do not like the leg lift that have been described in other posts; they feel that it puts too much strain on the new joint.

    Take it one day at a time and try not to get impatient with your recovery. Good luck!

      We are all different and of course guided by our surgeon & allied health practitioners but once that prosthesis is embedded then don’t limit yourself & get as strong & mobile as you can. I’m 9 months post revision & psoas release & use my concept rower & spin bike. 

      I walk every day & do strength work. 

      All the best and I hope you get back on your rower soon??

      Thanks for your encouragement! I’m 13 weeks post op, so have to be patient. In the meantime, I can use our elliptical and do laps in our swimming pool.

    It's all a matter of balancing the risk of dislocating.  You should be able to start bending by 12 weeks (but this is not universal, take advice from your surgeon). By 6 months, the risk is very low, there is always a risk, but there always was a risk before your THR.

      Hi Graham, thanks for your reply and the links you have provided they are very useful and I will be adding some of these exercises to my daily routine!

      I'm now finding that the exercises go on for life ..... just to keep the new joint going properly.

      We need to keep those muscles toned.
