After total hip replacement surgery, is it normal for the operated leg to be a little bit longer than the good one?

Can be. While I wouldn't call it normal, leg lengthening is a potential result of total hip replacement and can be no big deal or a significant disability. Leg lengthening has become less common with newer implants and surgical techniques. Significant lengthening can be balanced with a heel lift in the other shoe.
Yes. During hip replacement surgery, the soft tissues around the hip are tightened by varying the length of the prosthesis. Although the restoration of equal length is desired, sometimes, a slight increase in length is necessary for stability. Your body is used to walking with flexed hip prior to the replacement surgery. This plus the loss of cartilage height can lead to a perception of a longer leg.
Normal? No. As arthritis of the hip progresses, the joint collapses and the leg becomes slightly shorter. When hip replacement is performed, it is our goal to re-establish the 'normal' length of the leg, so the joint and muscles work best. If the other leg is 'good', then the lengths of the two legs should be equal after surgery. It may feel initially slightly longer, but should feel normal within 3-6 mos.

Leg swelling after I had a total hip replacement surgery. Did they do wrong?

Not necessarily. Leg swelling is not unusual after hip replacement, however, it can also indicate more serious conditions like blood clots. Make sure you express your concerns with your surgeon so that they can examine your leg to determine if the swelling is normal or not.
Not unusual. It is very common to get leg swelling after total hip or knee replacement. Of course, swelling with pain can be a sign of DVT (deep venous thrombosis). Also described by some as "blood clots". This should be evaluated by your doctor. Painless swelling will often resolve after a few months.

Should do hip re surfacing or total hip replacement for young patient of 26 years of age. Does after surgery there is change in legs length.?

Usually not. Unless there was shorting before, I do not think so.
Both good options. The decision to have either hip resurfacing or total hip replacement is one that you need to discuss with your orthopaedic surgeon. There are advantages and disadvantages for both procedures. The younger the patient at the time of surgery, the more careful the decision should be made- further surgery in 15-20 years may be necessary and needs to be realized before the first surgery.

How is leg length discrepancy measured after total hip replacement? How long should one wait to evaluate?

Let me explain. Limb length discrepancy can be measured by a physician during a physical examination and through x-rays. Usually, the physician measures the level of the hips when the patient is standing barefoot. A series of measured wooden blocks may be placed under the short leg until the hips are leveled. If the physician believes a more precise measurement is needed, he or she may use x-rays. (scanogram).
Exam and x-ray. Surgeons are careful at the time of tha to equalize leg lengths. In some cases the hip will be more stable if slightly longer. Many patients will feel that the operative leg is longer the 1st month after surgery but in fact it is not. An exam and x-ray will show the true leg length and I do this at 6 weeks. Stretching exercises will resolve the feeling of it being longer.

Please tell me how long it takes for to recover from total hip replacement surgery?

6 Months. It takes 3 to 6 months to recover from hip replacement surgery. If you have long standing arthritis you will have immediate pain relief of your arthritis but incision pain and muscle weakness will take longer to resolve.
6-12 weeks. Most patients are about 90% recovered by 6 weeks after primary tha. At this time most patients are walking, driving, and getting around quite well with little or no pain. The soft tissue healing goes on for 3-6 months so there may be ongoing improvement in function over that time.
3 months. The arthritis pain is gone immediately, but it takes about 6 weeks to feel better than you did before surgery. Three months to return to all normal activities. I tell patients that it will be a year before you reach maximal improvement.

I had a total hip replacement in oct. Of 2011 - how long before I can bend my leg past the 90 degree angle, cross my legs, etc.?

Depends on rehab. Total hip replacement is a major procedure that requires rehabilitation exercises. One's mobility after surgery depends on the effectiveness of the rehabilitation. Talk with the surgeon who did the surgery for specific recommendations.
6 weeks. Most surgeons that use these precautions will do so for 6 weeks. Other surgeons may not use these precautions depending on the surgical approach they use or their comfort level with the hip stability at the time of surgery. The reason is to allow the hip capsule and soft tissues to heal adequately to avoid a dislocation which can occur when the hip is flexed and internally rotated.
6 weeks. We recommend posterior hip precaution s for 6 weeks in our patients who had a posterior approach.
